    Interesting, shows you what I know:) I would like to know though how much overhead this creates. This won't matter in the context of a normal midi controller but it might matter when timing is critical like with a...

    I must confess that I actually don't know what is considered best practise in this regard, using multiplexers, shift registers or other approaches. You'll probably have to take care of the debouncing yourself as simple...

    How to use the multiplexer is explained here: Analog Multiplexer/Demultiplexer - 4051. Personally, I like using shift registers for adding digital inputs and/or outputs, see SN74HC165 shift register revisited....

    Typical you would use arrays to store the note numbers and buttons (state), then you loop through the button array and if the button is pressed send the note stored in the note array. There's an example of how this...

    As I understand it these motorised pots are intended for use with a simple 'up and 'down' remote control and not for use as a servo like with motorised faders. They are also quite slow as it takes several seconds to go...

    As the position of the pots will not match the plugin settings when switching channels you might want to add a button to send the current position of all pots to the plugin.

    There's an example of a 3 x 3 midi interface that does what you want (Interface_3x3). Look in the Arduino IDE under File > Examples > Teensy > USB_MIDI.

    Yes it does, and no you don't need to have the IDE open. The mode mode you specify on programming is kept as long as you don't change it through the IDE.

    Good to hear you're making progress. I would be interested to know what kind of precision and repeatability you're getting with the motorfaders.
