keyboard interaction bug?

[panavrin]

For MUI key rack, note off event is not triggered while command key (Apple keyboard only) is pressed.

For example, press Command + C will make the note sustain forever until C is pressed again.

Cheers!

What should happen when modifier keys are pressed? I thought about the possibility of playing notes with different properties. (velocity or octave, etc.)

Any suggestion?

Well, honestly, I liked the fact that I can sustain the note without having my finger keep pressing the key. :) In which case, it should be explicitly stated somewhere in the document (or let window users have the same feature with another key?)

On the other hand, I think it should not mapped to anything since user may want to use key for some other reasons (for example to copy (command) +c during the performance?). Or exactly opposite: user does not want other effect to happen when playing keys (command + s gives a sustained note and open "save as" popup window at the sam time?)

I see. That's a feature then. Still the behavior should be documented and all the MUI elements are severely undocumented. (like zero documentation.)

On the other hand, I think it should not mapped to anything since user may want to use key for some other reasons (for example to copy (command) +c during the performance?

This is also a valid point. I have not tested how preventDefault() on a keyboard event will apply to the case.
