So, if you have Ableton and M4L and want to do this…there you go
(Ableton settings should be fairly obvious, but to make it crystal clear. Set your Midi From to receive it from the Elektron device. Point it to the same Elektron device and on the channel you have setup for the FX channel.
I’m only asking because I don’t know not because I’m insinuating that I know something you don’t, but won’t this have unpredictable results? I’m assuming you tried this already and you’re reporting on what worked, so when you send like an all notes off command, everything stops? It’s not like internal midi loopback where you may have to pull the plug to stop the ride?
