I have an MC6 Controller which outputs MIDI to a Voodoo Lab Hex Audio Loop Switcher (MIDI Channel 1) and then to a Disaster Area Designs NNB Neunaber Expanse MIDI Bridge (MIDI Channel 2). The NNB is setup to have the MultiJack function as MIDI output to a Chase Bliss Tonal Recall (MIDI Channel 3). I connected the required MultiJack Cable for Chase Bliss Audio which has TS on one end and TRS on the other. USB power is provided to the NNB to support the demands of the MultiJack MIDI output functionality.
PC messages to the Tonal Recall work as expected. I can recall presets without an issue. CC messages have partial functionality. If I send a CC message of number 102 with a value of 127 the pedal does engage however, if I send a CC message of number 102 with value 0 the pedal doesn't disengage. Tap tempo works with a CC message of number 93 and any value. The issue seems to be when a specific CC value is required.
If I disconnect the NNB and use a MIDI Box in it's place (changing no settings on the MC6) everything works as expected. I've tried this with 2 seperate Tonal Recall pedals and different cables and the behavior is the same. The issue seems isolated to the NNB however, I'm wondering if there are any additional settings on the MC6 which could be tried to resolve the CC value issue. I'm also wondering if the Disaster Area Designs controllers work differently when sending CC MIDI messages to devices over a MultiJack. They do say "PLEASE NOTE we do not support the use of these cables with any other types of MIDI controllers". It's possible this is just an incompatibility but I wanted to exhaust all options before trying to figure out how to cram a much larger MIDI box on my board.
