Ableton Forum

Currently (Ableton 11) while recording loops, if you hold the sustain pedal past the end of a loop, the sustain disappears completely on playback. Currently, this requires you to release it right before the end of your loop if you want sustain to work at all on playback. (This is different than the issue of pressing the sustain pedal before the recording starts, which is less of an issue for me).

Yes, you can edit the sustain automation or note lengths after the fact, but this cannot be done during a live performance, which is where Ableton is supposed to shine.

As a keyboard-heavy user, this is nearly a deal-breaking problem for me. I can't reliably time my release of the sustain pedal to the exact end of a loop without either releasing it too soon and cutting off the sustain early, or releasing it too late and completely breaking the sustain on the loop's playback. There have been complaints about this issue for over a decade according to my extensive searching, without any real solution that I can find that would work during live performance.

If anyone already knows of a fix that works for live performance, please let me know. Otherwise, this definitely needs some attention, as it is likely a big turnoff to keyboard users.

Could you solve this? I have the same concern!

It’s a common issue, that’s because of how MIDI works unfortunately. I can’t think of a solution that would work on every situation.
That said, I just had an idea involving m4l :
What if a M4L device would automatically switch the sustain off when a clip loops or reaches its end ? Would it work for you ?
