Ableton Forum

Ableton triggers my Roland FA's instruments when booting up. It also makes the same sound when making changes in Link/Tempo/MIDI in Preferences. It doesn't seem to be doing it for other changes. It is definitely related to my Roland FA keyboard because when I change the instrument being played by the Roland, it changes the sound triggered by Ableton booting up.

Is it in my Roland or in my Ableton Lite? I have been doing some experiments trying to get Ableton to play the instruments in my Roland with some success.

Another clue.

This appears to be happening when my MIDI output is set to my Roland FA and the output Control Surface is "Roland FA". If I change that output to "none", this problem does not occur.

Also, the volume of this sudden noise is controlled on the keyboard and sometimes it cycles endlessly.

What is happening?

Late follow through. I factory reset my Ableton according to instructions I got elsewhere and this seemed to cure the problem.
