Pitch Drop When Using Sustain 1

2011-05-12 by lucidsound

Has anyone else come across the quirk whereby if using long release times in Sustain Mode 1, the oscillator pitch drops slowly when the notes are released?  Switching to Sustain II brings the notes back to the correct pitch.

I figure this is something to do with the Keyboard SH card, and voltages leaking away from the capacitors.

Any suggestions or previous experiences of this problem welcome!

Thanks,

Lucid.
