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.
The vibrato LFO shape can be selected from a variety of options and smoothly changed
between them.
The LFO speed and the vibrato depth can themselves be modulated by two extra LFOs.
A ‘bias’ control is provided to change the effect from simple vibrato to something more
like a traditional chorus or flange. Feedback can also be applied to give deeper, more reso-
nant flanges or to produce echo effects.
The plug-in works as a generic
n

processor i.e. it will do mono-to-mono, stereo-to-
stereo, 5-to-5 etc.. Good hosts will also allow its use as a mono-to-stereo effect (e.g. Logic
does this). A ‘spread’ control is provided to offset the LFO phase per channel - giving a re-
sult much like a classic ‘stereo chorus’ effect.
