I have had HEX for a while now. I initially had problems with it 'not playing well' with the Control Switcher when both HEX and CS are in MIDI mode. But then I bypassed the problem by using the CS in GCX mode using my old DMC Ground Control. (orig thread here: viewtopic.php?f=9&t=6876&p=23428)
But now, I added another MIDI device to my pedal board (Source Audio Ventris reverb), and the garbled MIDI messages coming out of the HEX are problematic once more.
The problem was never with the Control Switcher, but with the MIDI output of the HEX.
It seems I am not the only one with this problem. Here are a few threads describing the same bug:
- HEX MIDI OUT flakey viewtopic.php?t=12414
- Problem with Voodoo Labs Hex + Control Switcher: viewtopic.php?t=7576
- Voodoo Hex MIDI Out "ghost" PC Messages: viewtopic.php?f=9&t=12523&p=34798
- Hex problems: viewtopic.php?f=9&t=9200&p=29041
- https://www.morningstarfx.com/forum-2-1 ... thru-issue
None of these threads provided a solution.
My MIDI chain is as follows: DMC Ground Control -> HEX -> Ventris -> Control Switcher
I put a midi monitor right before and after the HEX.
I can see that the Ground Control properly sends 3 Program Change messages to the appropriate MIDI channels. Normally, I should get the same 3 messages coming out of the HEX but that is not always the case.
Usualy, the MIDI output from the HEX is ok, the same 3 messages are re-sent as-is from the HEX.
But sometimes, way too often to ignore, the HEX outputs around 15 messages. Among these are the 3 original Program Change messages, the rest being other Program Changes that make no sense. I never sent these from the Ground Control, they are being generated by the HEX and affecting every MIDI device downstream with wrong Program numbers.
I can provide screenshots if needed, but that gear is at my rehearsal space, it would take a few days.
Has anyone resolved that issue yet?
