Interfacing Arduino with Logic Mixer

...and how to do so...

I've been playing around the the Arduino and the motorised faders from the Yamaha DM2000 (https://www.thomann.de/gb/yamaha_ls_901 ... _fader.htm). So far I'm able to read the input value and touch sensitivity from the slider, and tell the motor to slide to particular values supplied over the serial interface.

Now I'd like to be able to use the fader to read from/write to a volume fader in Logic. What would I need write to make this happen? Would the software be in the form of a MIDI effect that sends/receives values over the serial port to the Arduino? Are there any standardised interfaces for this kind of thing?

Not that I actually knew much about this, but I think many 2-way DAW controllers use the Mackie HUI protocol.

Generic control surfaces often just use MIDI CCs, and most DAWs support that, so you possibly only need to be able to pack/unpack MIDI messages over serial/serial-over-USB.

As an option, you can also hack the other Atmel processor on a proper Arduino, the one that handles USB, so that it behaves like a standard USB MIDI device, which is a trick I found out is used on the miniAtmegatron synth.

That wont work for certain cheap clone Arduinos, eg those using CH340 serial controllers, though.
my other modular synth is a bugbrand

Thanks guys, some good info there! I'll try the HIDuino method, and update this thread with my findings.
