So I added a MIDI file with Kontakt Studio Drummer as a plugin on the MIDI track.
I must say it was hard for me to generate the erroneous behavior, weird since it happened all the time yesterday.
Anyway, you can see any time you're splitting the track the weird 'loop-like' appear (see attached image).
Exactly at the start of the region (11 A - solo 2) the few MIDI notes there do exist but are not sounding at my laptop. I think this might be representing the behavior I dont understand in general.
Thanks for your help!
