If Mike's suggestion is correct, there is a way to filter out MIDI input information that is either too short or too soft to matter. I had to do this recording my wind controller, which was sending a storm of MIDI info. The other part of Mike's idea involves the polyphonic limit of a MIDI hardware synth. Mine, for example, coughs at over 64. This doesn't mean 64 simultaneous notes, either; one note might send 4 or 6 or 1 signal toward that 64 limit. Having said all that, I doubt that is the problem here.
