Yeah, sure… nothing is perfect.
My concerns are not just based on faulty updates.
M4L API in Ableton Live 12.3
The new version of Ableton Live 12.3 has a big issue in the M4L API.
The issue was reported to the Ableton support and after some test case they have been able to reproduce the issue.
There is a new public beta version available and the issue has been fixed in this beta version.
