For CQ, soft key set to either Previous/Stop/start/Pause or Next cannot be controlled via midi.
It’s possible to ‘virtually’ press the SoftKeys using MIDI as described here –

This then means that any of the SoftKey functions can be controlled remotely.
e.g. You could send a note on every beat to control a tap tempo or control the stereo/multitrack recording as you want to here.
If you mean that you’ve tried this and it’s not working for some reason though, please contact us through support.allen-heath.com with example messages and more info on the setup so we can assist.
Cheers!
Keith.
