Introduction Warbler Warbler is at heart a vibrato effect, with additional controls that allow chorus/flange/ delay type effects, as well as quite unusual hybrid sounds that aren’t easily categorised. The vibrato depth ranges from subtle modulations to extreme pitch effects. The vibrato LFO (low frequency oscillator) can be set from 0Hz to 5kHz and is controlled by 3 knobs to allow accurate control over the whole range.
Installation Mac OS X Simply copy the plug-in to the appropriate folder: Library/Audio/Plug-Ins/Components for the Audio Unit version, or Library/Audio/Plug-Ins/VST for the VST version. Windows Simply copy the plug-in to your VST plug-ins folder. System Requirements Mac OS X Warbler requires at least Mac OS X version 10.2.8. Version 10.4 or higher is recommended. The plug-ins are Universal Binaries and so will work on PowerPC or Intel Macs. The Audio Unit version will work in any Audio Unit host.
Registration The downloadable version of Warbler stops working after 15 minutes every time you use it. To stop this happening, you need to buy a registration. You can buy a registration key online using a credit card or PayPal from the Expert Sleepers Licence Manager application. See here for more information. Note that you need at least version 1.0.6 of the Licence Manager. The e-commerce side of things is handled by eSellerate.
Using Warbler Using the controls Knobs Basic use of the knobs is to click on them and drag the mouse up and down. However you can obtain different results by holding keys as follows: • • • Shift : Values change more slowly as you move the mouse. Command1 (Mac OS X)/Alt (Windows) : The knob assumes its default position. Option 2 (Mac OS X)/Control (Windows): The knob assumes integer values only. Value edit boxes These boxes (below each knob) let you enter parameter values directly.
The LFO type is set by the shape knob. Default is ‘sine’ - try turning it fully to the right to select ‘square’. The ‘Mix’ knobs default to 100% wet, 0% dry i.e. you only hear the effected signal. Raising the dry level will mix the two signals, resulting in a familiar ‘ensemble’ effect or thickening of the sound. Chorus/flange effects Turning the ‘Bias’ knob all the way to the right (value of 1.0) configures the plug-in as a traditional delay-line based chorus/flange effect.
The controls in depth Speed The 3 speed knobs together set the main LFO speed. Their values are simply added. The readout above the knobs shows the current speed value being used (NB this also takes into account the Speed LFO - see below). The knob ranges are • Superfine: 0-1Hz, useful for very slow modulations. • Fine: 0.5-20Hz, useful for normal vibrato effects. • Coarse: 10-5000Hz, useful for audio-rate modulation sound effects. Speed LFO The Speed LFO modulates the Speed value set above.
this control method, which might seem odd to those used to chorus/flange effects where you set the delay time in ms directly. Depth LFO The Depth LFO modulates the Depth value set above. It has simple speed and depth controls. This is most useful when bias (see below) is set to 1.0, though you can of course use it whenever you like and it will always do something to the sound. Shape The ‘Shape’ knob changes the shape of the LFO waveform. There are 5 key shapes, and the control blends between them smoothly.
Chorus/Flange The ‘Bias’ control fundamentally reconfigures the effect from being a vibrato to being a traditional modulated delay-line chorus/flange. It does this continuously however so there is a huge range of possibilities between the two extremes. When bias is set to 1.0 (i.e. it’s in chorus/flange mode) using the Depth LFO to modulate the depth often sounds good. The ‘Feedback’ knob introduces feedback into the delay line. This is commonly used in flange effects to create a more ‘resonant’ sound.
Preferences Pressing the ‘Prefs’ button brings up a dialog where various preferences are set. These settings are shared by all instances of Warbler, and are not stored with presets. The top section shows the product version. The central section will show your serial number once you’ve bought a registration. OSC Base Port sets the base port number for OSC. See the section on OSC, below. ‘Constant redraw’ is on by default. If turned off, the GUI is only redrawn when a control changes.
MIDI control All of Warbler’s parameters can be controlled via MIDI CC’s (Continuous Controllers) according to the table below.
OSC Control Warbler can be controlled via the Open Sound Control (OSC) protocol. If you’re new to OSC, start by visiting opensoundcontrol.org. Two settings control what port the plug-in uses to listen on for OSC commands. One is the base OSC port, set in the preferences. The second is the OSC Port Offset control. If the port offset is set to something other than ‘Off’, then the two numbers are added together and the result used as the port number. E.g.
