My poly synth patch is working as polyphonic when incoming notes events are at different timing, but when they come at exactly at the same timing (by using ‘chord’ message or using Ableton), it sounds monophonic. Does anyone know why this is happening?
I'm not sure I understand why, but the second (not connected) thispoly~ object in the poly patch (km.sine_poly.maxpat) seems to cause the problem. After deleting it everything works fine.
