Try setting Ableton Live up like this screenshot. This is using Overbridge to get the audio from each Digitone track on a separate track in Live, and also to control midi on each track in the Digitone via midi.
First go to settings > Audio Routing on the Digitone, and leave the menu highlighted on “Route to Main”.
Press the 4 track buttons on the Digitone so they turn red. You’ll see the screen says Route to Main 3/7 - this stops the audio going to the Digitone Master, so you can have them on separate tracks in Ableton.
Then go to Ableton and create 4 audio tracks, and 6 midi tracks.
Add the Overbridge VST to the first midi track. For this example, name that midi track “Digi Master” -set the midi input to none.
Go to the first audio track you just created and choose “Digi Master” as the input source, then select Track 1 L/Digitone in the next box. click the “in” button below it. Then go to track 2, do the same, but select Track 2 L/Digitone in the second box, then do the same for 3 and 4 - selecting Track 3 L/Digitone and Track 4 L/Digitone.
Audio from the Digitone tracks will now play on separate tracks in Ableton, and the effects will play in the “Digi Master” track.
Now go to the 2nd midi track you created, the one after the Digitone VST track. Name it “Digitone Auto Channel” and select “Elektron Digitone” (or whatever your Ableton named the midi input form the Digi) as the destination, and set it to midi channel 10.
If you want to use Push 2 or a keyboard to record into the Digitone’s sequencer, use this track - it will send the midi to whatever track you have selected on the Digitone.
Now go to the 3rd midi channel you created, Set the output to “Digi Master”, and set the midi channel to 1. Do the same to the remaining 3 channels, and set them to midi channel 2, 3, and 4 respectively.
These tracks will now send midi to each of the 4 Digitone tracks. You can use these to record midi in Ableton for each track if you don’t want to use the Digitone sequencer, or if you want to send extra midi data to each channel from Ableton as well as using the Digitone sequencer.
