With its set of novel features, however, JAWS has no real world counterpart: Firstly, it
includes an envelope to modulate the number of folds and an LFO to modulate the
bias out-of-phase per audio channel (which results in a unique stereo effect). Secondly,
JAWS can serve as a simple distortion unit by setting TEETH (the number of available
folds) to zero. Here is a typical wavefolder setting:
6 TEETH, about 25% FOLDS (the solid line) with some positive BIAS (shifted to the right)
FOLDS knob: How much of the wavefolder curve is being used. This is effectively an
input volume control, so setting FOLDS and F-MOD both to zero will result in silence.
TEETH rotary switch: Sets the total number of folds in the wavefolder. Zero here
means simple distortion, while 2 to 6 deliver more typical wavefolder effects.
BIAS knob: If B-MOD is OFF , this knob shifts the part of the wavefolder curve being
used. If B-MOD is either MIN, MED or MAX, it adjusts the depth of modulation from
the wavefolder’s own LFO – in opposite directions for each stereo channel, hence the
stereo effect. Note that the stereo effect is not monosum-compatible, and that extreme
BIAS settings can result in silence anyway, especially if FOLDS is set relatively low.
B-MOD switch: Bias modulation LFO rate. Setting this to OFF disables the LFO.
F-MOD knob: The depth of folds modulation from the wavefolder’s own envelope…
A and R knobs: A ttack and R elease times for the wavefolder envelope.
TRIGGER switch: Determines how the envelope reacts, with the following 3 options:
ASR stands for attack-sustain-release – the envelope proceeds through the attack stage
and stays at maximum as long as a note is held, after which it releases. AR is a
one-shot attack-release envelope with no sustain. Finally, the LFO option is similar to
AR but is triggered by Repro-1’s main LFO instead of the gate.
Tip: In general, wavefolders deliver more interesting effects when applied to relatively
simple waveforms e.g. a pure triangle from oscillator B, a sine wave from the filter
when self-resonating, or any other mellow sound.
Note: The sound of the Wavefolder is sensitive to minuscule differences in signal level
and phase between the various sample rates. If you notice that your JAWS-based
preset sounds very different when you switch sample rates, try adjusting the FOLDS
settings to compensate, then save as “name-of-preset (96k)” or similar.
