Short version: Could anyone please use either a MIDI keyboard or the Kontakt 8 keyboard and hit A4 with Modular Icons (any patch) and see if that note hangs for them?
Long version: I think I found a bug but I want to see if it's just me. I'm in Logic Pro 11.1.2 on a Mac mini M2Pro. I have Kontakt 8 instantiated as a multi-out 16x stereo. I went into the Logic environment and created a 16 channel 'multi-instrument' and connected it to Kontakt (yes I removed the previous assignments) and assigned new midi channels to Logic to map different MIDI tracks to Kontakt instruments assigned to those respective MIDI tracks.
I tried to load myriad other instruments and only Modular Icons seems to do it.
