Programmable Parameters
Source 1 (Src1)
This parameter takes its value from a long list of control sources including every MIDI
control number, a host of LFOs, ASRs, envelopes and other programmable sources.
Src1 works in tandem with the parameter beneath it on the page: Depth. Choose a control
source from the list for Src1, then set a value for Depth. When the control source assigned
to Src1 is at its maximum, the pitch will be altered to the full depth you set. For example, if
you set Src1 to MWheel, and set Depth to 1200 ct, the pitch will rise as you push the Mod
Wheel up on your Forte or MIDI controller, reaching a maximum of 1200 ct (12 semitones,
or one octave).
Source 2 (Src2)
This one’s even more programmable. Like Src1, you choose a control source from the list.
But instead of setting a fixed depth, you can set a minimum and maximum depth, then
assign another control source to determine how much depth you get.
