I have harmony on all 4 voices(separated!) in a program on my XD3.It was in the factory for repair,I've got new software 2.1a but problem is still there.I have Roland A33 connected (A33OUT to IN2(keybd),A33 transmiting on global channel and I tried all combinations in MIDI setups.XD3 users,any sugestions? I'm sure solution is couple of push buttons away.
