Hello,

The problem is always when two H9 are connected.

I think that you have a bug about Thru parameter MIDI. It is not correct.

Examples connection with MIDI port only :

1 – Output MIDI port PC > Foot Controller MIDI FCB 1010 > H9 (parameter Output on XMT) > Input MIDI port PC = H9 Control works correctly with a H9

2 – Output MIDI port PC > Foot Controller MIDI FCB 1010 > H9 (parameter Output on Merge) > Ventris reverb > Input MIDI port PC = H9 Control works correctly with a H9

3 – Output MIDI port PC > Foot Controller MIDI FCB 1010 > H9 Core > H9 Max  > Input MIDI port PC = Only a H9 is visible in H9 Control (see table below)

4 – Output MIDI port PC > H9 Core > H9 Max > Input MIDI port PC = Only a H9 is visible in H9 Control (see table below)
