Ok little update:
I got a used Launchpad Mini MkI today and it's the same problem here. Sending Midi from Ableton works, from Axoloti not.
I tried to do a test run with the Launchpad since it's only Midi Notes I have to check with that one but I get the Buffer overflow all the time, also when I set the Lfo really slow.
This is my test patch:
how can I turn of note off messages? I think I have to go really slooooow when testing so it indeed it seems more practical to get rid of note offs. I don't want to sitting here staring at that thing all night waiting for lights...
Furthernmore: Here is an example of the LCXL in use with something other than a pc:
The creator mentions that for the Novation launch series devices have "special support". Maybe a hint that they react differently on Midi input then other controllers?
P.S. this is what I Axoloti tells when connecting the LP mini:
