- I would be very surprised if that were the case. The Kurzweil 1000PX
- had a parameter to turn that behaviour on and off. I tried turning it
- on (re-using the same channel for a repeated note) and many patches
- sounded downright unnatural. Consider a slow string pad with long
- attack and decay times. Pressing the key of a note that is still
- sustaining would cause that note to be cut off and begin its slow
- attack again. Yuck!

- I can't speak for GMIDI but different manufacturers pride themselves
- on their note stealing algorithms. Of current equiment on the market,
- by and large a new note will always steal an already existing note.
- The hard part is to determine which existing note to steal. Perhaps
- the oldest. Perhaps the note whose decay level is the lowest. Perhaps
- the lowest pitched note will *never* be stolen because the bass is
- more noticable. Some synths will steal individual layers from multi-layer
- notes hoping nobody will notice.
-
- I sincerely hope GMIDI doesn't attempt to stifle further progress in
- this area.
