Midi problems

The purpose of this patch is is to run signals from a ewi and let it "count" itself through a number of pre-decided chords. The note of the ewi decides the bottom note of each chord. A it is now, the patch works fine until you start playing legato; if it doesn't detect a note-off before you strike the next note, the previous note will hang. Now, according to the help files there are a few objects that could help out with that: poly, flush of midiflush. However, it seems that whatever i do, it doesn't really do the trick. (There is one weird thing i had to do in order to make it work as it does now: the [pipe 0] should not actually doing anything, but in this case it works for note-offs). As soon as you start playing legato, the notes are hanging.
