M4L live.object grab_control and Midiout/Ctlout, can't MIDI map on Ableton Live
I'm trying to use live.path, live.object and grab_control to hijack a button in a MIDI controller, to then output MIDI CC to the Ableton Interface. I need to control the stock Looper device using MIDI assignments, as some of the Looper controls are not available vía live.remote~ (undo/clear, x2, etc)
The device sits on a MIDI Channel, and aims to control LOOPER in a separate audio channel.
My patch successfully takes over the button (outputs MIDI to ableton using either midiout/ctlout), the channel actually outputs MIDI, and the remote MIDIlight flashes on the top right, but I'm unable to MIDI map it to any parameter.
I got inspired by the following video, where I understand she is using MAX standalone and the IAC driver.
Is there something I'm missing here to make it work from Max4live?
I forgot to mention I'm using Max 8.6, Ableton live 12 and the IAC driver is the internal mac MIDI driver.
