Hi. My name is Duwayne I created a script of the A-Series and the M32 works with FL Studio. It's called the Fruity NILA.
By using the Native Instruments Host Integration protocol instead of the limited MIDI mode Native Instruments provides, the controller acts as if it was connected to Ableton or Logic Pro X. The Komplete Kontrol App and/or Plugin does not have to be running for this script to function. FRUITY NILA doesn't interfere with the operation of the Komplete Kontrol Plugin.
You must have Komplete Kontrol v2.3.0 or higher, Firmware 0.3.9 or higher and FL Studio 21 or higher.

I would love to make a script of the S-Series but I don't own one. Would love if Native Instruments could send one my way since I've added a bunch of value to the A-Series and the M32. My script works flawlessly, making the controls a great option of FL Studio (the most popular DAW in the world).
