Course pitch modulation

Is there a limit to how much you can modulate Course Pitch of an oscillator?

Using an EG, I can get an octave+third of pitch change, but no more. I tried making two modulations with the same source and destination to increase the result (like an Oberheim Xpander will) but that didn’t make any difference.

I also tried several modifiers without sucess. Maybe I’m using them incorrectly? Any hints?


The coarse modulation is plus/minus 16 MIDI notes (1 octave + major third) by design.

The only way to go beyond this is by modifying the voicecard code (changing the shift value here)

Got it - thanks :slight_smile:

Hmm… with an offset & bipolar source I should be able to get a total of ~2 1/2 octaves of pitch change. Will that out when I get home!


It doesn’t work this way… All modulations are summed together and clipped into a single value - so adding an offset will not allow you to go outside of this range.
