@lintfresh that's weird. Just checked and all seems to be working well over here. Are you using the standalone or the M4L device? Could have something to do with your MIDI I/O settings.
-> Set up an IAC bus. Go to MIDI Preferences (in Ableton). When using the M4L device, set both 'remote' and 'track' to 'on' for the input and 'track' to 'on' for the output of the created IAC bus. Now choose the IAC bus you just set up in the 'MIDI To' dropdown on the track the 'control' device sits on.
When using the standalone, just put the input's 'track' and 'remote' to 'on' and you should be good to go.
If it doesn't work, try disabling MIDI devices that you're not using.
i did find a bug with autofocus on the m4l device - will fix it later on today, but that shouldn't influence your MIDI mappings
