I've been using an AKAI APC mini for about 6 months now to control various parameters. I have way more parameters to control than faders that the APC mini has (only nine), so I built a small external to switch between "scenes" of the faders, so I could control as many as I need.
I find that occasionally the controller will update the value of its faders without actually touching it. This wouldn't be a problem if the faders were permanently assigned to one and only one parameter, but since the assignment is constantly changing, the updated value potentially messes up an entire scene, especially since I'm not even touching it.
Has anyone experienced a similar issue? Is it something to do with midi controllers in general? Or with the way Pd interacts with the controller?
