I've run in to a bit of problem designing a MIDI controller with lots of knobs. There is code to forward incoming MIDI messages from other controllers to the MIDI Out in the main loop, and that should run as fast as possible. This means it's better to not poll all the knobs (there are about 40 of them) in the main loop unless it's absolutely necessary.
So what I'd like to do is get an interrupt signal from the multiplexer whenever a knob is changed and an update is necessary. Is there an elegant way of doing this, or perhaps even a multiplexer that provides such a function?
