Using Pro Tools 2018.7.0, can't playback through the 24R. I saw a similar post answered by AlexTinsley who said:
"Pro Tools has a limited I/O of 32 In and 32 Out, since the output streams for the 24R (or any Series III Console or Rack Mixer) are outside that range, not all is lost, as of firmware release 1.7 with Universal Control 2.6 released in April 2018, you can repatch your I/O inside the mixer. You would need to repatch your USB (or DAW) outputs be inside the Pro Tools 32 Channel limit so you can hear your audio."
I'm noticing in this latest version of Pro Tools there are 64 outputs showing in the I/O setup (32 stereo pairs), so it seems there should be compatibility for playback, but I can't make it happen.
Any suggestions would be greatly appreciated.
