On the new screen you should see several sync options.
Click on the check box of the last one (1) to select LIVE SYNC - PROGRESSION BUILDER
(CHORDS, VOICING, TIMINGS).
Once selected, click on the START LIVE SYNC (2)
After a few moments (the cursor will be turning), you will see your progression copied to Scaler 2.
Ignore LEADER in Scaler Audio and FOLLOW texts displayed inScaler 2. They are used for full live sync. As I did several tests before taking screen shots they were there at the moment of the capture.
The last step: In my case, I needed to press Esc to go out of the Scaler Audio, then reselect it in its track. Button STOP LIVE SYNC - ALL will appear. Click on it.
When this button disappears and SYNC button appers, pres Esc on your keyboard and that’s it.
I am glad that this worked for you. I am Reaper user and my experience with Ableton is limited to about 15 minutes max, years ago, but I was sure that our friends on this forum, Ableton users, would help you. This is a great community.
