Yes, there are multiple connections available for MIDI. On your unit, it looks like TRS 1 and TRS 2 use 1/4" TRS to MIDI and the TRS 3 port uses 1/8" TRS to MIDI.
For the Graviton M1 to QC something like this would work.
You can also go with the 1/8" TRS (think smaller headphone jack) if you are using the TRS 3 port. CME and Morningstar usually sell those cables as well.
WOW… I’ll try that, once I get the regular setup working. If I could, via USB both Power the Graviton and Receive MIDI messages… that’s like icing on the MIDI Cake
Midi on Graviton M1 : either DIN or TRS 1/4 or TRS 1/8
Midi on QC : DIN
Midi on QC Mini : TRS 1/8 type A
Best cable for QC : DIN - DIN / Possible : TRS 1/4 - DIN or TRS 1/8 - DIN but always TRS type A !
Best cable for QC Mini : DIN - TRS 1/8 type A
Wireless system : plug a Widi Master in the QC or a Widi Jack in the QCM and use Midi via Bluetooth on M1 - no need to power le the Widi Jack, and you can use it on the QC too.
