Hi @Paolo
The CQ sends and received MIDI messages as detailed in it’s MIDI Protocol here – https://www.allen-heath.com/content/uploads/2024/10/CQ_MIDI_Protocol_V1_2_0_iss4.pdf
You can also use the A&H MIDI Control Driver to translate between the CQ’s NRPN messaging and CC messaging as per the A&H MIDI Control Help Doc – https://www.allen-heath.com/content/uploads/2024/06/AH-MIDI-Control-V2.10-Help_Iss1.pdf
MIDI messages can be used to control all kinds of things, but a few things that might help you here:
– The CQ uses NRPN messages, which are different to CC messages, so to use these with other equipment/software, that must also work with NRPN messaging. OR you will need to use the CC Translator option in A&H MIDI Control
– Turning knobs or pressing keys and buttons when controlling a CQ audio channel does not send MIDI messaging from the controls. The controls adjust the parameters in the CQ core, and it’s these changes which are sending messages.
Hope this points you in the right direction – you could also get something like MIDI OX or Pocket MIDI to take a look at the MIDI being sent, to then work out how you can apply it in Reaper.
Thanks,
Keith.
