SETUP Function
S/HSpeed = 0,...,127
Knob 4
Turn the knob to set the sample & hold speed for the LFO (low-frequency oscillator).
This setting determines how the LFO operates on samples whose LFO Wave parameter
is set to S/H. Specifically, the setting determines the "sample and hold" rate used for
random LFO modulation. (Note that the term "sample" in "sample & hold" refers to
sampling rate, and is unrelated to A3000 sound samples.)
This setting has meaning only if the program uses at least one sample for which
Wave=S/H. If the program uses two or more such samples, then the speed you set here
applies to all of these samples.
