Ableton play command from SC

Questions
1

What are the simplest ways to start Ableton with SC?
ie. A command to trigger the play button in the Ableton transport controls…

TIA,
Lewis

I’m not sure but have you tried Ableton Link?
I remember jack had a simple transport panel to use but you have to use JACK as audio interface.
of course you can always use MIDI with Ableton live API.

Simplest is probably to send a midi note or cc from SC and map it to whatever control you want in Ableton

You can also use max4live to receive osc and use the live API but this is more complicated

Thanks I’ll have a look at that

Yeh I’ve used MIDIDef to start logic.
What is the cc number for the transport start button in Ableton?

6

Or is it .noteOn I don’t have my old code to hand…

Just had a look on Grok & it says to send a sysex message using MIDIDef…

I don’t know, but Ableton’s manual says “All manual MIDI, computer keyboard and Macro Control mappings are managed by the Mapping Browser” – which I take to mean that you might be able to define your own CC or note mapping to the transport control.

If you’re using an actual MIDI control surface, you could also have SC receive the play/stop messages and print them out.

IMO RTM would be more trustworthy than an LLM (especially one that’s had some negative press recently). That “sysex” sounds like a guess to me, since Ableton documents a panel where CC and note mappings may be created and removed.
