Sound Parameters Sound Parameters Overview of Functions Waldorf Iridium consists of numerous sound-shaping components. The following pages describe all parameters in detail. Note that Iridium consists of two different types of components for sound generation and sound shaping: • Sound synthesis: Oscillator models, Filters, Digital Former, Amplifier, Effects. These modules represent the audio signal flow. Sound generation actually occurs within the oscillators.
Sound Parameters Iridium offers three oscillators with different capacities: Wavetable Oscillator, Waveform Oscillator, Particle Generator, Resonator, and Kernel synthesis. Oscillator Section The most important oscillator controls can be found in the Oscillator section on the Iridium’s user panel. Choose the desired oscillator model by pressing the corresponding button. To enter the Kernel mode, press Wavetable and Waveform buttons simultaneously. The button of the chosen model lights up.
Sound Parameters The Wavetable Oscillator Wavetable Oscillator Panel Parameters A wavetable is a table consisting of single waveforms. Each waveform is classified by its own special sound character. The main difference of wavetable synthesis in comparison with other sound-generation principles is the ability to not only to play one waveform per oscillator but also to step through the wavetable via different modulations, thereby creating wavetable sweeps.
Sound Parameters Noisy higher values speed it up. Cyclic means, that a wavetable starts automatically again from the beginning when the end is reached. If you don’t want a cyclic modulation, use the Position parameter modulated with an envelope, an LFO, or any other modulation source. You can also set up different Travel Modes. Please refer to the corresponding section below. This parameter adds a noisy sound character to the wavetable oscillator.
Sound Parameters • Set Default: sets Semitones to its default value 0. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Modulations: opens the Mod menu to sets up a modulation for this parameter. How to set up a modulation can be read in ‘The Modulation Mode’ chapter. In contrast to the stepped nature of the semitone control, the pitch modulation is changing the pitch continuously according to the modulation source shape.
Sound Parameters • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter. • MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter.
Sound Parameters • Osc 1/2/3 Dest MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter. Here you can determine the routing of the corresponding wavetable oscillator signal. The following routing options are available: Osc 1/2/3 Pan Determines the stereo panning position of the corresponding oscillator. Tap on Osc 1/2/3 Pan to open a pop-up menu for further settings: • Normal: Oscillator panning change is about 2 %.
Sound Parameters • MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter. • RingMod (only available for Osc 2 and 3) PB Range Osc 1, 2 or 3 Controls the volume of the ring modulation between Osc 1 and 2 (for Osc 2) or 1 and 3 (for Osc 3). r Determines the intensity of the pitch wheel in semitones for the selected oscillator from -24 to +24. Negative values inverse the direction of the pitch bend.
Sound Parameters meter. The higher the value, the stronger the variation. Setting this parameter to 0 will disable this variation. While each oscillator of each voice has an individual out-oftune coefficient, the PitchVar parameter is global to all oscillators of all voices. Timbre Mode Tab Here you find specific parameters for the wavetable generators. Tap on PitchVar to open a pop-up menu for further settings: • Set Default: sets Pitchvar to its default value 0.17.
Sound Parameters Position Tap on Wavetable to open a pop-up menu for further settings: • Set Default: sets the wavetable to its default Resonant. Same functionality as for the corresponding panel parameter. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. Tap on Position to open a pop-up menu for further settings: • Modulations: opens the Mod menu to sets up a modulation for this parameter.
Sound Parameters wanted. Turning Phase to maximum value will result in a “Free Running” phase much you would expect from an hardware oscillator. • Super Fine: Spectrum change is about 0.02 %. • Set Default: sets Spectrum to its default value + 0.0 %. Tap on Phase to open a pop-up menu for further settings: • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Modulations: opens the Mod menu to sets up a modulation for this parameter.
Sound Parameters • Set Default: sets Brilliance to its default value 0.0 %. • Super Fine: Keytrack change is about 0.01 %. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Set Default: sets Keytrack to its default value 100.0 %. Modulations: opens the Mod menu to sets up a modulation for this parameter. How to set up a modulation can be read in ‘The Modulation Mode’ chapter.
Sound Parameters Mode up Travel in musical values. The highest amount is 1024, where one turn needs 1024 beats. • One Shot: a wavetable stops when the last wave is reached. The last wavetable position is played and held. Every played note starts its own travel cycle. • Ping Pong: a wavetable automatically starts a reverse playback when the end is reached and vice versa. Every played note starts its on travel ping pong cycle. • Global P. P.
Sound Parameters • Wrap: uses a smooth interpolation when Travel reaches the end of the wavetable and blends back to the start wave position. This setting is useful when the Travel Mode is set to Cycle. • Limit: uses no interpolation as in older Waldorf wavetable synthesizers (e.g. Microwave) when Travel reaches the end of the wavetable and blends back to the start wave position. • 2/4/8 Steps: only every second, fourth, or eighth wave is interpolated. This creates a harsher sound for some wavetables.
Sound Parameters • Set Default: sets FX Type to its default setting Drive. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter. single cycle of a wave. Good sizes are from 200 to 1024 samples. The size can be odd. You could use longer files but waveform will be averaged to a maximum of 1024 samples in case.
Sound Parameters Presets Button can be configured in import dialogue window from 64 to 4096, many popular synths use 2048. • • r Tap on the Presets button to open a pop-up window for loading, saving, and managing Wavetable oscillator settings. Here, the following options are available: Load Wavetable: imports a wavetable from the internal Flash memory or a connected MicroSD Card/USB storage device. This enables you to exchange user wavetables with other Iridium users.
Sound Parameters The Waveform Oscillator Waveform Oscillator Panel Parameters Iridium offers a standard oscillator model to create typical analog synthesizer waveforms (sawtooth, triangle etc.) plus other classic waveforms like square (which is the father of the pulse waveform) and the sine wave (also part of every other waveform). Also, different noise signals can be choosen. Semitone / Octave Sets the pitch of the oscillator in semitone steps.
Sound Parameters Detune • Detunes the multi oscillator when Count is set to any kernel value greater than 1.0. White Noise is a fundamental source for any kind of analog-type percussion. It offers the same level over the complete frequency range. Wind and other sound effects can also be created by using noise. Shape Warp Use this knob to select the desired waveform. The following waveforms are available: Depending on the selected Shape, the Warp function alters the basic shape of a waveform.
Sound Parameters • for the Wavetable oscillator. Please refer to the corresponding chapter. If Pink Noise or White Noise is selected, the Warp parameter blends from a filtered noise (lowest setting) into the corresponding selected noise (middle setting) to a pitched noise (highest setting). Timbre Mode Tab Here you find specific parameters for the Waveform oscillators. Sync Adds a typical oscillator synchronisation to the selected oscillator shape (except Noise types).

Sound Parameters Semitone 1 - 4 you want to create drum-like sounds where every played note sounds similar during its attack phase. Here you can individually transpose the first four oscillator kernels in semitones. If more than four kernels are selected then kernels 5 to 8 use the same pitch settings as kernels 1 to 4. Tap on the corresponding Semitone button to open a pop-up menu with semitone settings from -12 up to +12. • Set Default: sets Phase to its default setting Running.
Sound Parameters MicroSD card/USB storage device into Iridium’s internal Flash memory and load it from there into the Particle generator. The Particle Generator This generator creates its sound by playing back audio samples. There are two different ways of sample playback: normal playback and granular playback. Read more about the sample playback in the following chapters. • From audio recordings done with Iridium. The Global page features an audio recorder.
Sound Parameters Particle Generator Panel Parameters Detune/Pitch Spread (only in Granular Mode) Semitone / Octave Determines the amount the grains that are displaced from center pitch, when Count/Grain Poly is set to any kernel value higher than 1.0. Sets the pitch of the particle generator in semitone steps. The standard setting for this parameter is 0, but there are cases where different values are interesting as well.

Sound Parameters The Resonator Resonator Panel Parameters The basic concept of the Resonator is sound creation by using an initial exciter signal (mostly a short noise impulse) which goes through a bandpass filter bank, where its resonating filters finally produce a ringing sine-like sound. Based on different Timbre modes, the partials of this signal can be adjusted in many ways. Semitone / Octave Sets the pitch of the Resonator in semitone steps.
Sound Parameters Spread Q Extends or compresses the partials of the resonator, which leads to massive timbre changes. There are two Spread modes that can be set at the Resonator display page. Determines the resonance of the created partials. The higher the setting, the longer the duration of the created sounds.

Sound Parameters ons for velocity, various key tracking possibilities, plus presenting feedback, level, pitch, and wavetable position as modulation targets in the Iridium’s Modulation Matrix. The Kernel Synthesis Mode = Press Wave- table and Waveform buttons simultaneously to activate the Kernel mode for the corresponding oscillator 1, 2, or 3. The whole oscillator section lights up in pink.
Sound Parameters Kernel Mode Panel Parameters Kernel Mode Display Page Semitone / Octave To access the Kernel Mode display page, press the corresponding OSC 1, 2 or 3 button above the touchscreen display. Sets the pitch of the kernel in semitone steps. The standard setting for this parameter is 0, but there are cases where different values are interesting as well. Press and hold the Semitone dial while turning it enables you to select the pitch in octave steps.
Sound Parameters else than read-only presets. So, you could create a new template by doing some deep edits on the Kernel level and then going back to the template screen and save it as an Oscillator preset. Then you can use this preset in another oscillator or in another sound design session as your own starting point. You can also save a preset without deep editing just to save the 5 pot settings for a particular template for later re-use.
Sound Parameters r In Kernel mode, each oscillator consists of 6 kernels. You can view these kernels as oscillators in itself which can be freely connected by various modes. You select between editing each kernel by the row of K 1…6 buttons. Each Kernel has then 4 sub-pages: Wave, Mod, Env and Level. To the left there is also an overview section (Patch button) which is then initial screen when getting first into Edit Mode and you can also switch by tapping on the Patch button.
Sound Parameters The Kernel Display Pages This page is an overall control page with no additional functionality for the kernels. Tap on the kernel button on the top of the page or withion the algorithm graphic (K1 to K6) to open the corresponding kernel. Kernels are abbreviated by K1, K2 etc. and “Out” means the output of the oscillator. Tap on one of the K1...K6 buttons in the first row to switch to the corresponding Kernel display page. This page is identical for all of the six kernels.
Sound Parameters On the right you will find the Out button which determines if the kernel’s output is send and mixed into the oscillator’s output. If output is activated, there is a Solo button shown, which is handy for layered algorithms with multiple kernels sending to the output. With Solo you can quickly experience each kernels sonic component to the overall sound. and such. For these and take use of user wavetables, talk, spectrum etc. you have to use the main Wavetable mode.
Sound Parameters tial or overtone relationships (in whole numbers) For fractions use Fine or Super Fine modes. • Sub-Ratio Mode: Like Ratio mode, just using dividers instead of multipliers for getting undertones. K1...6 Detune adds an additional detuning interval up to +/-50 cents (100 cents is one semitone). • Ratio + Offset: Like Ratio mode but having a parameter K1...6 Offset which detunes by a fixed value in Hertz instead of an interval.
Sound Parameters The Mod Page and such). In case of multiple modulation sources their signals will be simply summed. Tap on one the Mod button to switch to the corresponding Kernel display page. This page is identical for all of the six kernels. r Please keep in mind that the amount of modulation is determined by the level of the modulating kernels. This is a central and important fact for these kind of synthesis. K1...
Sound Parameters The Envelope Page up both levels to get a strong sound. Ring modulation is also a typical scenario where you could set the modulating kernel to a fixed frequency. • • Tap on one the Env button to switch to the corresponding Kernel display page. This page is identical for all of the six kernels. AM is similar to Ring with the main sonic difference that lowering the level of the modulating kernel would keep more and more of the sound of the target kernel.
Sound Parameters K1...6 Level and K1...6 Sustain stage, that are nontimebased parameters. Both can be set in percent (%). K1...6 VeloDepth determines if extend lower velocities should lower the overall signal. This parameter is identical to the corresponding parameter on the Level page. The Level Page K1...6 Level controls the overall level of the kernel signal. This parameter is identical to the corresponding parameter on the Level page.
Sound Parameters In addition the level can be adjusted in accordance to the played key. If you have set a low and a high key split point., you can rise or lower the curve depending on the K1...6 Low and HighBias parameter. Split points and bias can also be graphically edited by tapping and moving your finger up or down. K1...6 LowSplit defines a low key split point for level scaling. K1...6 HighSplit defines a high key split point for level scaling. K1...
Sound Parameters made something interesting, just save it as a oscillator preset and re-use your template in other sounds. That is what Kernel synthesis makes a true oscillator construction kit. Macro selects one of the five knobs for further editing. The follwing display graphic shows the assignment. For example, the Top-L (top left) knb is Ratio, the Bottom-R (bottom right) is Decay.
Sound Parameters With the top right parameter you can set the value for the selected knob. This can also be done in the center of the display, where you can edit the name of the knob thta is shown in the display. Step-by-Step Tutorial for setting up a simple 2 Operator FM without using a template: • Tap on Load and INIT the sound. Macro Dest determines the parameter that should be assigned to the selected knob. • Press Wavetable and Waveform buttons of OSC1 simultaneously to enter the Kernel mode.
Sound Parameters • Tap on Env and change the K2 envelope to some interesting curve. • Congrats: You’ve constructed your first kernel oscillator template! You can stop here and play around, or you like to set up a custom template with these steps from here: • Select K1 again to edit kernel 1. • Goto Wave, set K1 Type to Wavetable, choose a wavetable as you like but leave position at 0. • Goto Patch -> Controls. • Select Macro to Center from top left encoder. • Keep Slot at 1.
Sound Parameters Oscillator Mixer (OSC MIX) Section In the Oscillator Mixer section you control the volumes of the three oscillators. If an oscillator volume dial is turned fully counterclockwise, no signal is passed. Level Osc 1 / Osc 2 / Osc 3 Determines the volume of the corresponding oscillator. Routing Button Press the Routing button to enter the Routing display page. Read more about signal routing in the Filter chapter in the corresponding section.
Sound Parameters Dual Filter Section r Iridium offers two filters with different types and additional settings (e.g. 12 dB/24 dB Lowpass with resonance clean, saturated or dirty). With the Link parameter different filter routings can be realized (e.g. Boost, Twin Peaks, Escaping, Opposition and many more). The Dual Filter section can be bypassed by setting all Osc Dest parameter on the corresponding Oscillator Control display pages to DF 100 Fil 0.
Sound Parameters necessary signal adaption is done by a saturation stage. This leads to a harsh driven audio signal. cussion-like electronic toms, kicks, zaps, etc. The functionality of these knobs depends on the Type setting. Type 1 / 2 Selects the filter slope for the corresponding filter: • 12dB LP / 24dB LP removes frequencies above the cutoff point with a 12dB/24dB slope. • 12dB sat. LP / 24dB sat. LP removes frequencies above the cutoff point with a 12dB/24 dB slope.
Sound Parameters tomatic cutoff value depending on the settings of Cutoff 1. This leads to a boosted signal. Resonance 2 has no influence here. • Twin Peaks: both filter cutoff values are set to a constant frequency distance where Cutoff 1 is higher than Cutoff 2. Cutoff 2 and Resonance 2 have no influence here. • Escaping: both filter cutoff values are set to a constant frequency distance where Cutoff 2 is higher than Cutoff 1. Cutoff 2 and Resonance 2 have no influence here.

Mod Targets Button Read more in the ‘Modulation’ chapter. Single Trigger All envelopes offer a single trigger function.
Sound Parameters LFO Section Speed In addition to the main oscillators, Iridium is equipped with six low frequency oscillators (LFOs) that can be used for modulation purposes. Each LFO generates a periodic waveform with adjustable frequency and shape. Determines the frequency of the selected LFO. At low values it might take four minutes for the LFO to perform a complete cycle while higher values are in the audible range.
Sound Parameters • The Square shape can be interesting for hard pan modulations or special effects. • The Saw (down) shape can generate interesting filter or volume changes. It creates a falling sawtooth wave. • The Saw (up) shape can generate interesting filter or volume changes. It creates a rising sawtooth wave. • S&H (Sample & Hold) samples a random value and holds it until the next value is generated. If Speed is set to 0, a random value is generated on each new note.
Sound Parameters • Fine: Speed change is about 0.28 Hz. • Super Fine: Speed change is about 0.028 Hz. • Set Default: sets Speed to its default value of 6.25 Hz. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Modulations: opens the Mod menu to sets up a modulation for this parameter. How to set up a modulation can be read in ‘The Modulation Mode’ chapter. • If Saw (down or up) is selected, the waveform is folded. Settings below 0.
Sound Parameters • Normal: All Amounts change is about 2.0 %. Decay • Fine: All Amounts change is about 0.2 %. • Super Fine: All Amounts change is about 0.02 %. Controls the speed with which the LFO is faded out. With this parameter you can create slowly falling modulations that might create interest when routed to pitch or volume. Attack Tap on Decay to open a pop-up menu for further settings: Controls the speed with which the LFO is faded in.

Tap on the desired name to select it and load it immediately. Already made effect settings will be overwritten. 3) Select the desired effect from the effect list. • 4) All effect types can only be used once.
Sound Parameters The Effect Types of Iridium Phaser Phase shifting is a sweeping effect that was first popularized in the 1960s. It adds motion and a swirling character to the sound. It works by splitting the incoming signal, changing the phase of one side, and recombining it with the unaffected signal. This creates a notch-comb filter that can be swept through the frequency spectrum, causing the signature ‘whooshing’ sound of the phase shifter.
Sound Parameters Spread Model Controls the phase position of the Phaser signal. Lower settings produce a more resonant Phaser effect. Determines the Phaser model that is used. You can select between the Phaser from Waldorf’s Nave and PPG Wave 3.V. Feedback Tap on the corresponding effect parameter to open a popup menu for further settings (not all settings are available for all effect parameters): Controls the feedback amount of the signal.
Sound Parameters Chorus Dry/Wet A Chorus effect is generated by using comb filters that generate slightly detuned copies of the input signal and mix it into the output signal. The result sounds like an ensemble of several simultaneous sounds, like a choir as opposed to a single voice – hence being called Chorus. The detuning is generated by an internal LFO that can be controlled in speed and depth. This parameter controls the volume ratio between the original signal and the effect output.
Sound Parameters Shape • Set Default: sets the parameter to its default value. Determines the shape of the LFO waveform, which is used for the chorus modulation. You can select between a sine and a triangle waveform. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Modulations: opens the Mod menu to sets up a modulation for this parameter. How to set up a modulation can be read in ‘The Modulation Mode’ chapter.
Sound Parameters Flanger Dry/Wet The flanger effect is very similar to the chorus effect, but features feedback circuitry to feed the generated signal back into the comb filter. This generates a deeper detuning and colorizes the signal. With extreme settings you can hear a whistling sound which is very characteristic of a flanger effect. This parameter controls the volume ratio between the original signal and the effect output.
Sound Parameters Shape Delay Determines the shape of the LFO waveform, which is used for the flanger modulation. You can select between a sine and a triangle waveform. A Delay is an effect that produces echoes of the input signal. Tap on the corresponding effect parameter to open a popup menu for further settings (not all settings are available for all effect parameters): • Normal: parameter change is about 1%. • Fine: parameter change is about 0.1%. • Super Fine: parameter change is about 0.01%.
Sound Parameters Feedback Sync Controls the amount of signal that is routed back into the Delay line. Lower values, therefore, produce fewer echoes than higher values. Synchronizes the delay to the internal tempo of the Iridium. If activated, you can set up Delay-L and Delay-R in musical values. Delay-L LR Linked Sets the length of the Delay tap for the left channel in milliseconds or rather seconds. If Sync is activated, the delay length can be entered in musical values.
Sound Parameters • Normal: parameter change is about 1%. Reverb • Fine: parameter change is about 0.1%. • Super Fine: parameter change is about 0.01%. • Set Default: sets the parameter to its default value. The Reverb effect is probably the most widely used effect in music production. Iridium’s reverb effect is an addition to the sound to make it more expressive with a threedimensional feel. • Set Last Loaded: resets the parameter to the last loaded value from the current sound patch.
Sound Parameters Time • Determines the reverb time. Lower settings simulate a normal room while higher settings simulate a big hall or church. Set Last Loaded: resets the parameter to the last loaded value from the current sound patch. • Modulations: opens the Mod menu to sets up a modulation for this parameter. How to set up a modulation can be read in ‘The Modulation Mode’ chapter. • MIDI Learn CC: activates MIDI Learn, which maps an incoming MIDI control change to this parameter.
Sound Parameters EQ (Equalizer) EQ Dry/Wet Iridium offers a parametric equalizer to adjust the sound frequencies to your needs. This parameter controls the volume ratio between the original signal and the effect output. If set to 0%, the dry signal is sent to the output only so that no effect can be heard. Higher values will increase the effect signal. At maximum setting of 100% the pure effect signal will be heard. Low Freq Controls the cutoff frequency of the low band.
Sound Parameters High Freq Master Gain Controls the cutoff frequency of the high band. This shelf filter type looks like a normal or an inverted ‘S’ and it works and sounds similar to a hi-pass filter with adjustable stop band attenuation or boost. Working with an equalizer mostly affects the level of the output signal. Use Master Gain to adjust the overall gain to suit your needs.
Sound Parameters maximum setting of 100% the pure effect signal will be heard. Drive Adds gain to a signal causing it to clip and distort. It introduces new harmonics that add a harsh edge to sounds. Amount Determines the amount of saturation that is added to the signal. If set to 0.00%, no saturation will be added or, in other words, the signal will remain clean. Lower values will add some harmonics to the signal, resulting in a warm character.
Sound Parameters • Compressor PickUp simulates an electrostatic pickup. This drive type sounds very interesting, when the audio signal level is modulated. • Diode generates a typical diode distortion. • Crunch is a sinusoidal waveshaper. It generates FM-like sounds that can be extremely distorted. An Compressor reduces signals which exceed a certain Threshold level in volume by an adjustable Ratio.
Sound Parameters Threshold Look Ahead Determines to which signal level the compressor will be working. Only signal levels above threshold are processed. Higher Look Ahead values produce more accurate processing, but adds a certain amount of latency. Input Gain r Determines the input gain of the incoming audio signal. Attack Determines how fast the compressor responds to audio signals above the set Threshold.
Sound Parameters The display shows the Modulation Assignment window. The basic concept is to select a modulation destination first (a parameter or function to be modulated), then select a modulation source (a function, such as an LFO or a wheel, that will modulate the destination) and finally determine the amount of modulation. This is also called modulation depth or intensity. The Modulations of Iridium Modulation can be described as a signal-generating unit’s influence upon a sound parameter.
Sound Parameters 3) You can also select one of the six modulation sources in the display. Turn the corresponding dial (e.g. wheel) to select the desired modulation amount. 4) You can add other modulation assignments by repeating step 2.

Appendix *+,./0121/3 If Attack is 0 and Decay set to a medium value you get a percussive sound; if you turn up the attack, you get a softsounding start.
Appendix overtones. The following picture shows the sine wave and its frequency representation: Waveform Oscillators Introduction The oscillator is the first building block of a synthesizer. It delivers the signal that is transformed by all other components of the synthesizer. In the early days of electronic synthesis, Robert A. Moog found out that most real acoustic instrument waveforms could be reproduced by using abstracted electronic versions of these waveforms.
Appendix Cyclic waveforms such as the waveforms in the Iridium only feature sine waves in integer frequency ratios to the fundamental like double frequency, triple frequency and so on. Those partials are called harmonics because their frequency is a harmonic multiple of the fundamental. !;2<=/'5>+1, ./0+12*3(+1, ./0+12*3(
Appendix pulling the string slightly into one direction. At one point, the string abruptly comes off the bow and swings back to its original position. The bow is still moved and so it catches the string again and the procedure is repeated. The result is a waveform that looks like a sawtooth. The same is true for a brass instrument. In this case the ‘string’ are the lips while the bow is the air. The lips are moved by the air to a certain extent and abruptly move back to their original position.
Appendix blows air through the tube in such a way that the air starts to vibrate. This vibration is almost completely symmetrical, resulting in a hollow timbre. #&'()*+,./0*12-(314-5 ! The Square Wave " # $ % !! !" !# ""'()*+,- The Square wave is the most versatile wave in a classic synthesizer because its shape and therefore its harmonic content can be changed in realtime. This is done by changing the width of the upper and lower portion of the waveform cycle.
Appendix symmetrical harmonic content while all other pulse widths create peaks or troughs at certain frequencies. Another special case is a pulse wave with a very narrow pulse width – labelled as < 1% in the previous image. An infinitely thin pulse creates a spectrum that has all harmonics with equal magnitudes. In a digital synthesizer, ‘infinitely’ necessarily means one sample. The Triangle Wave The Triangle Wave is very similar to the square wave.
Appendix The triangle wave sounds like a woodwind instrument – i.e. a clarinet. It can also be used for mallet instruments like vibraphone and xylophone, etc. !;2<=/'5>+1, ./0+12*3(+1, ./0+12*3(+1, ./0+12*3(+1, ./0+12*3(
Appendix A Short Introduction to Granular Synthesis Filter Introduction Granular synthesis is based on a simple idea: instead of playing back an entire sample, only short portions of the sample – the so-called grains – are played. These grains can be played back in any order. Each time a grain ends, a new one starts. To avoid discontinuities in the playback, and to minimize artefacts, envelopes are applied to the grains.
Appendix effect of the resonance parameter on the filter’s frequency curve: )#*#+ )#*#+ 0#1.&2&'# !"#$%#&'( ,%-.// !"#$%#&'( To give you an idea of the extent of damping, consider this example of a lowpass filter: a reduction of 24dB reduces the original level one octave above the cutoff point by approx. 94%. The damping factor two octaves above the cutoff point reduces the original level by more than 99%, which in most cases means this portion of the signal is no longer audible. ,%-.

Appendix Arpeggiator Glossary An arpeggiator is a device that splits an incoming chord into its individual notes and repeats them rhythmically. Most arpeggiators feature different sequence modes to cover a wide range of applications. Typical controls for an arpeggiator are the octave range, the direction, the speed and the clock, which means the repetition interval. Some arpeggiators also feature preset or programmable rhythm patterns.
Appendix Coffee Filter Envelope A coffee filter is a coffee-brewing utensil, usually made of disposable paper. It is part of an essential toolkit for survival when working with the Waldorf Iridium. An envelope is used to modulate a sound-shaping component within a given time frame so that the sound is changed in some manner. For instance, an envelope that modulates the cutoff frequency of a filter opens and closes this filter so that some of the signal's frequencies are filtered out.
Appendix Filter Cutoff Frequency significant advance. It made it possible to link any MIDIequipped device with another through simple, uniform connections. The filter cutoff frequency is a significant factor for filters. A lowpass filter dampens the portion of the signal that lies above this frequency. Frequencies below this value are allowed to pass through without being processed. Essentially, this is how MIDI works: One sender is connected to one or several receivers.
Appendix channel is set to the same channel as the one the sender is using to transmit data. Consequently, the sender can address specific receivers individually. MIDI Channels 1 through 16 are available for this purpose. Panning MIDI Clock Pitchbend The MIDI Clock message determines the tempo of a piece of music. It serves to synchronize processes based on time. Pitchbend is a MIDI message.
Appendix Sustain lope’s current status. For instance, the Release phase may be initiated during the Attack phase. An envelope parameter. The term ‘Sustain’ describes the level of an envelope that remains constant after it has run through the Attack and Decay phases. Sustain lasts until the trigger is terminated. Resonance Resonance is an important filter parameter. It emphasizes a narrow bandwidth around the filter cutoff frequency by amplifying these frequencies.
Appendix Volume will probably sound smooth and pleasant. If they have a completely different structure then this will result in wild spectral changes. The term describes a sound's output level USB The Universal Serial Bus (USB) is a serial bus system to connect a computer with an external device. USB equipped devices can be plugged together while active. The recognition is made automatically.
