Well...

• knob support for some built-in plugins
• automatic mod wheel and pitch wheel support on plugins that have that function (set range to 12 on Pitch in the Channel Window for Pitch to function correctly)
• volume control in the piano roll for the selected sound
• quick quantize works
• red box around mixers under control

if FL Studio is active (you can tell if Scale & Arp buttons are not lit) press in this order, Instance (Shift+Track), PLUG-IN MIDI. Knob function has now returned to the Komplete Kontrol Plugin.

if you want to assign the eight knobs yourself, go to MIDI Mode. To do this hold shift and press MIDI. Assign the knobs as you wish. You have four pages of knobs to do so. To return to full control mode, Press TRACK

I'm planning on making videos of features this month at https://www.youtube.com/@the.man.from.toronto

I do... but would need to know what version of FL Studio you're using and what version of the firmware you have installed on the keyboard?

I'm guessing you meant 21.0.1. Either way, glad it worked out for you!
