Is the TCP protocol available?

[JB_J]

I’d like to build a remote control based on an ESP32 to start/stop multirack recording, and display the status.

These command are not available via MIDI, but are via the TCP protocol used by MixPad.

Is the TCP protocol documented somewhere?

Allen and Heath do not reveal their in house protocol. One way round this is to program your soft keys as motor control functions, then remote trigger over midi. I have done this for SQ. I know there are far more soft keys on SQ so it may not be a solution in your case.

Given the requirement to match the same version number for the app and firmware, I expect the implication is that the network protocol isn’t documented because it’s not guaranteed to stay the same. You can always inspect network packets to reverse engineer but there’s no guarantee that it won’t be broken at some point.

I have developed this prototype that surfaces the recording and playback control as MIDI:

Emellan MIDI extender app for CQ

I’m creating an independent iOS utility app that will allow us to extend the MIDI implementation of the CQ mixers. This will eventually include controlling absolute FX delay time, SD playback and file navigation, FX in/out, Listen, Phantom power, gain, custom midi channels and other things that are currently missing in the CQ. All midi mappings will be configurable by the user. The app will be free. [IMG_1713] [IMG_1715] I will soon be looking for enthusiastic beta testers. Will you join?

However I stopped that project while developing this:

MiniDucq - a ducker for the CQ mixer

The CQ finally gets a ducker! MiniDucq is here and you can test it today by following the link: Join the MiniDucq beta - TestFlight - Apple [Ducking on the A&H CQ using MiniDucq] This is an early beta version that has only been tested with the CQ20B with the latest FW version as of writing.
