DRIVE FUNCTION
The DRIVE function is operational only when CHORD MODE is active. It applies a variable amount of gain
(between 1 and 3) to output1, followed by a cubic saturation process. The purpose of this function is to com-
pensate somewhat for the loss of amplitude experienced due to phase cancellation of the multiple waveforms
when in CHORD MODE. The saturation keeps the peak amplitude within limits, and provides a nice soft rolloff
of the peaks for most waveforms. In some cases the result may sound distorted at high DRIVE levels.
To set the nominal value of the DRIVE parameter, press the TILT/DRIVE button. If CHORD MODE is active, the
DRIVE parameter value can then be adjusted with the rotary encoder and will be shown in the bottom row of
the LCD display. The DRIVE parameter can also be modulated by the MOD B input, which is activated with a
second press of the TILT/DRIVE button. When MOD B modulation is active the lower row of the LCD display will
change to show both the nominal setting and the offset provided by the MOD B modulation.
The output of the nonlinear waveform combiner, after going through the envelope amplifier, is passed through
a simple comb resonator/delay line. For short delay times this acts as a resonator, and at long delay times
it provides an echo effect. The DELAY parameter sets the amount of feedback from the output of the delay
line back to its input, and also sets the wet/dry mix of the input and delayed signals. As the DELAY parameter
increases, the resonator depth, or the echo regeneration increases. At the same time the wet/dry ratio in-
creases. This is needed to prevent saturation or clipping at higher feedback levels, and means that the level of
the input signal gets lower and lower as the DELAY parameter increases. At the maximum DELAY setting the
feedback is 100% and the input is 0% and the delayed signal will be infinitely repeated (a hold or freeze effect).
This can be used in performances to provide overdubbing or looping effects. To do this one quickly changes the
DELAY parameter (using the MOD B knob as described in the next paragraph) to 0, plays some material, then
quickly changes the DELAY parameter to 99 to hold and repeat the material just played.
To set the nominal value of the DELAY parameter, press the DELAY button. The DELAY parameter value can then
be adjusted with the rotary encoder and will be shown in the bottom row of the LCD display (on the display it
is labeled as echo rather than delay). The DELAY parameter can also be modulated by the MOD B input, which
is activated with a second press of the DELAY button. When MOD B modulation is active the lower row of the
LCD display will change to show both the nominal setting and the offset provided by the MOD B modulation.
The DELAY parameter does not specify the delay time, however. The delay time is set by the period of oscilla-
tor 2. This permits synchronized LFO echo effects when oscillator 2 is in LFO mode, and produces pitch syn-
chronous resonator effects when oscillator 2’s pitch follows that of oscillator 1 (as when QUANT is turned on).
The signal tracking the period of oscillator 2 is passed through a slew-rate limiter (low pass filter or smoother)
before using it to compute the delay time. This causes a pitch shifting when the pitch of oscillator 2 changes.
At long delay times (oscillator 2 in LFO mode) this produces long gliding pitch shifts, while at short delay times
(resonator effect) this slew produces flanging effects.
