Hey Jules -
Any chance you could add an isKeyDown() method for synth voices?
I'm doing a synth that does portamento (slide) from one note to another when a second note gets pressed, and need to distinquish notes that are playing with a key currently down from notes that are playing after the key is released ( isCurentlyPlayingNote() comes back true either way, as you know).
If I could just get get the value of keyIsDown, all would be solved!
