Looper issue with MIDI Controller

[romanw_85]

Hey there,

so I've searched a bit and found out that this problem exists for quite some time and others have encountered it (viewtopic.php?t=217122 for example), too but so far I didn't find a solution. The problem is as follows:

I have a MIDI foot controller (Morningstar MC3) which I want to assign to the looper.
I can play the first loop just fine. But once I want to clear it and play another one, what happens is that in the middle of the new loop, somehow the "undo" button is being triggered (which I haven't mapped!) so that the old loop is being played again. It doesn't matter what MIDI message is being sent by the MC3, CC, Note, always the same. But I still suspect the controller being the culprit here, because it doesn't appear when I control the Looper with the mouse. Can anyone help? Thanks!

Edit: I solved it. What happens is that Ableton needs a „Note Off“, or in my case, a CC message with the same number but with value „0“. Otherwise it thinks that a note (or a button) is being held, which leads to the „undo“-function of the looper. So I had to program the MC3 such that it sends a CC with 127 value on the pressing, and a value 0 on releasing the button.

Makes sense. Thanks for posting how you solved it.

WOW ! Thank you so much! After years of looping troubles, this finally solved it! Even the ableton support team couldn't help me with this...
