Ownerʻ‘s Manual
Owner's Manual VERMONA PERfourMER MKII Introduction In a choir, a string- or brass section, every voice has its own character, its sonic individuality, its proprietary modulation and its specific decay. Is this not possible for a polyphonic synthesizer? It is with the PerFourMer MKII! Each of its four voices are totally independent.

Owner's Manual VERMONA PERfourMER MKII Getting Started To ensure top quality we carefully inspected the PerFourMer MKII before packaging. Nevertheless, the unit could have been damaged during transportation. Therefore, we ask you to take a serious look at the instrument when unpacking. Do not hesitate to contact us, should there be anything unusual with the PerFourMer MKII itself or its packaging.
Owner's Manual VERMONA PERfourMER MKII Oscillator Section Oscillators form the base of every synthesized sound. They offer different waveform shapes to create various audio spectra. Each PerFourMer MKII voice offers a voltage controlled analogue oscillator (VCO), four VCOs in total. Every VCO generates sine, triangle, square and saw tooth waveforms with octave positions 32’, 16’, 8’ and 4’. Alternatively, white noise or an external audio input can be selected for each synthesizer channel.
Owner's Manual VERMONA PERfourMER MKII OCTAVE sets this oscillator's base octave to 32', 16', 8' or 4'. In setting "HI" and "LO" the oscillator doesn't respond to incoming pitch information. The oscillator constantly oscillates with a fixed frequency. GLIDE sets the duration of the glide-effect. This defines the time period for the pitch to travel from one note to the next played note. This function is also referred to as portamento or slide. It is well suited for solo work.
Owner's Manual VERMONA PERfourMER MKII dysfunctional with any other selected waveform. Using a sine waveform to modulate the pulse width results in a sound-thickening-effect, comparable to a slight detuning. With higher modulation intensities (70 % and higher), the oscillator will temporarily be muted depending on the LFO speed. Here, there pulse width is so narrow and the sound therefore partially inaudible.
Owner's Manual VERMONA PERfourMER MKII NOTE To achieve a classical sync-sound, set the coupled oscillator at least two octaves higher than the master oscillator or make sure, it heavily modulated by an envelope generator. It is also recommended to use a square waveform for the master-oscillator. However, other settings will also lead to good results. Frequency modulation of oscillators The PerFourMer MKII offers frequency modulation for the oscillators in synthesizer channels 2, 3 and 4.
Owner's Manual VERMONA PERfourMER MKII NOTE The PerFourMer MKII's FM-function is static in principle. To create dynamically developing FM-sounds, comparable to the famous DX-series synthesizers, make use of the envelope generator of the modulating synthesizer channel (modulator). For example, by applying a short decay to the VCA with sustain set to zero, the carrier-modulation takes only place for the defined decay-time, specified for the modulator.
Owner's Manual VERMONA PERfourMER MKII Filter Section (VCF) The filter shapes the oscillator's output signals, either one of the available waveforms, the noise generator's output or an external audio signal. Certain frequencies will be suppressed, resulting in subtle to significant sound changes. Dynamic control of the filter will create progressive sound changes over time.
Owner's Manual VERMONA PERfourMER MKII RESONANCE Resonance is a feedback circuit within the filter that emphasizes the cutoff frequency. Higher values can color the sound significantly, which is regularly used for resonant bass sounds in Acid-House and Techno. With values higher than 3 o' clock, the filter will start to self-oscillate, generating a sine wave with the cutoff frequency. This sound can even be played chromatically over a range of approx.
Owner's Manual VERMONA PERfourMER MKII Amplifier Section (VCA) A voltage controlled amplifier (VCA) controls each synthesizer channel's output. This allows manual control over the output volume as well as dynamic volume progressions. Available modulation sources are the envelope generator and a fixed gate-envelope, the latter offering minimal attack- and release-phases to avoid unwanted clicks caused by disadvantageous phase cuts during sound reproduction.
Owner's Manual VERMONA PERfourMER MKII PAN The PAN control places the synthesizer channel's sound within the stereo image. At its center position, the PerFourMer MKII's left and right outputs are fed with the same level. This control offers a center catch. Turning the control to the left shifts the level towards the left output until the synthesizer channel will only be audible from the left output. The same applies to the right output when turning the control clockwise.
Owner's Manual VERMONA PERfourMER MKII Modulation Generator (LFO) The LFOs (Low Frequency Oscillators) allow creating cyclic repeating modulations of the oscillators and filter. The PerFourMer MKII's LFOs offer a choice of functions that might not be seen at first glance: Its LFOs can be synchronized to each other and/or to a MIDI-clock. Also, they can be shifted against each other in phase.
Owner's Manual VERMONA PERfourMER MKII Extended LFO Settings Selecting between saw tooth and square waveforms EDIT-Parameter 7 allows changing of the LFO's first waveform. Edit function LFO WAVE 1: SQUARE can select between square or descending saw tooth. This selection is available for each synthesizer channel. The default setting as well as the reset default (see "RESET", page 30) for the first LFO-waveform is saw tooth. To switch to a square waveform, follow these steps: 1. Press the EDIT-button. 2.
Owner's Manual VERMONA PERfourMER MKII LFO > MIDI-clock-synchronization All of the PerFourMer MKII's LFOs can be beat-synced to a MIDI-clock. MIDIclock-synchronization can be enabled/disabled for each synthesizer channel independently using EDIT-parameter 8: LFO MIDI CLOCK SYNC. To do so, follow these steps: 1. Press the EDIT-button. 2. Select parameter 8: LFO MIDI CLOCK SYNC using the SELECT/SEQ control. 3. Press TRIG to enable synchronization for one or several synthesizer channels.
Owner's Manual VERMONA PERfourMER MKII NOTE Changes from one scaling factor to another will take place after a waveform cycle has been completed. Do not worry about a possible delay after switching at slower tempos - this is intended. Internal MIDI-CLOCK The PerFourMer MKII can also generate an internal clock to synchronize the LFOs. Its tempo can be adjusted using a TAP function. To use the internal clock as LFO clock-reference, follow these steps: 1. Press the EDIT-button. 2.
Owner's Manual VERMONA PERfourMER MKII Envelope Generator (ADSR) The envelope generator (EG) generates a control voltage that can modulate the VCO and VCF as well as the VCA. The envelope generator is restarted by each incoming MIDI-note. (Exception: With LEGATO enabled, overlapping notes will not retrigger the envelope generator.) The envelope contour is separated into four sections: Picture 5: The Envelope Generator ATTACK adjusts the rising time from zero to maximum level.
Owner's Manual VERMONA PERfourMER MKII Legato Each of the PerFourMer MKII's synthesizer channels allows its legato-mode to be enabled independently. In legato-mode, the envelope generator will not be restarted when note are played overlapping. To enable/disable legato-mode, carry out the following steps: 1. Press the EDIT-button. 2. Select parameter 6: LEGATO using the SELECT/SEQ control. 3. Press one or several TRIG buttons to enable/disable legato-mode for one or several synthesizer channels.
Owner's Manual VERMONA PERfourMER MKII Additional Control Elements TRIG The TRIG-button starts a single note or a sequence to play the PerFourMer MKII's sounds without any keyboard or sequencer attached. Whether a single note or sequence is played, depends on the setting of the SELECT/SEQ control. Set to positions 1 to 4, single notes are played in different octaves. Set to positions 5 to 16, different sequences are played in varying complexity.
Owner's Manual VERMONA PERfourMER MKII MASTER VOLUME This control sets the overall output volume. It affects the rear-outputs as well as the headphone output but it doesn't affect the individual synthesizer channel outputs. SELECT/SEQ During playmodes, SELECT/SEQ will select the single notes and sequences that will be triggered by the TRIG-buttons. Positions 1 to 4 will select single notes in different octaves, positions 5 to 16 select different sequences.
Owner's Manual VERMONA PERfourMER MKII 1V/OCTAVE CV INPUT/GATE INPUT (optional) The PerFourMer MKII can optionally be equipped with CV/Gate-inputs. With this option installed, all four synthesizer channels can be addressed by analogue sequencers and CV/Gate-keyboards. Each synthesizer channel is accessed thru its individual CV/Gate jacks. Polyphony is only possible, if the controlling sequencers and keyboards support polyphonic note output.
Owner's Manual VERMONA PERfourMER MKII Programming Section The rightmost section of the PerFourMer MKII's panel serves to adjust the MIDI-channels, EDIT-parameters and PLAYMODES with the addition of global controls for MASTER TUNE and MASTER VOLUME. Combining Multiple Synthesizer Channels The four PerFourMer MKII's synthesizer channels can be combined in different ways. Depending on the selected PLAYMODE, the synthesizer channels can be played monophic, duophonic or polyphonic.
Owner's Manual VERMONA PERfourMER MKII played independently PLAYMODE setting. NOTE in Mono-1-mode, disregarding the selected Mono-1-mode allows stacking of synthesizer channels. Here, you may use identical or different settings for oscillators, filters and modulators. With waveform, octave, filter etc. being adjusted roughly identical, the PerFourMer MKII will react like a common synthesizer with multiple oscillators.
Owner's Manual VERMONA PERfourMER MKII With oscillators, filters and modulators being set differently on all four channels and spread across the stereo image, a sequence can drastically change its sound when changing between Mono-1- and Mono-2-modes. Although, the same notes arrive at the input, the Mono-2-mode will give the impression of (up to) four new sequences, due to our ear separating the different sounds from each other. Using an odd number of notes per beat will increase this effect further.
Owner's Manual VERMONA PERfourMER MKII DUO 2 (D2) This PLAYMODE allows the two voice units to be played duophonically.
Owner's Manual VERMONA PERfourMER MKII Edit-Mode The edit-mode allows adjusting different settings for the individual synthesizer channels as well as global settings for the PerFourMer MKII. For easy handling, a list of all available parameters is printed to the unit's top-surface above the SELECT/SEQ control. To change a parameter, perform the following steps: 1. Press the EDIT-button to enter edit-mode. 2. Use the SELECT/SEQ control to select the desired parameter (1..10). 3.
Owner's Manual VERMONA PERfourMER MKII 6 - LEGATO This parameter enables/disables the legato-mode. With legato enabled, the envelope will not be retriggered with adjacent notes played overlapping. 7 - LFO WAVE 1: SQUARE This parameter enables/disables the alternative LFO square waveform shape. With this function enabled, a square waveform will replace the saw tooth waveform in the LFO. 8 - LFO MIDI CLOCK SYNC This parameter enables/disables LFO-synchronization to MIDI-clock.
