I'm trying to adapt the KBD Arpeggiate Partials sound, so when you play a key you start at the top of the spectrum and gradually descends down to the fundamental, the note you played. Poking around, it looks like the Spectrum Modifier is the place to tinker; specifically the HiTrack field:
(!LowTrack * 15) + ((!KeyDown ramp: (100 * !Sweep s)) * 256)
If I were able to substitute the ramp for an upside down ramp, would that do the trick? I don't see any reverse ramp in the Capytalk reference, which makes me think I'm missing something obvious. Thanks for any help!
