I’d suggest this is an Ableton question, as CC#0 is a valid thing, it just doesn’t seem to exist in the standard Ableton MIDI clip automation options (which also only goes up to CC#119).
One workaround would be to ‘shift’ all controller numbers by -1, either using max4live or an external MIDI translator (e.g. Bomes MIDI Translator).
If you need more help with this, please feel free to contact us directly using support.allen-heath.com
Thanks,
Keith.
