Bugs

Examples of behavior that appear to be bugs:

- Layers are sometimes delayed by about 2ms with respect to each other. One way to hear this by creating a program with two identical layers, one panned hard right, one hard left, then playing repeated notes. It is likely that the sound will occasionally appear to be panned hard to one side. What's happening is not panning, it's actually just your brain interpreting the delay as a sign the sound is coming from the other side. Creating a stereo keymap is the preferred way to do this kind of thing, and isn't subject to this behavior. (Not sure if this has been reported to Kurzweil.)

- The Roland DP-10 half-damper capable sustain pedal occasionally seems to switch polarity, so that it sustains when it's up and vice versa. Apparently it's known not to be fully compatible with the PC4. (Reported to Kurzweil.)
