Is there a way that I can use a MIDI software like Reaper to control a 16 channel relay board? I want to be able to control my relays and sync them with music for pneumatic actuation, and I've tried christmas light software, Vixen, and it just doesn't work how I need it. Could I find a way to use a software to output MIDI to control my relays?
The Arduino Uno does not support MIDI over USB natively. You could use an application on your computer that converts MIDI to serial, or you could flash custom firmware to the Uno's USB chip, but both options are cumbersome. If you want to use MIDI over USB, I would recommend a board that supports it natively.
You can find more information on Control Surface: MIDI over USB.
Yes there is of course.
Definitely !
There is of course another option. If you already have a USB-midi device as a part of a soundcard or midi-controller of some kind, (Using a DAW you may have one) then you can receive (true)midi on either the hwSerial or using swSerial, and all you would need is an opto-coupler a few resistors and a diode. The advantage of midi-cables is that you can cover a fair bit of distance.
I'm not looking for low latecny or anything, I'm not even working with sound. I just want to play sequences for all 16 channels of the relay board, using a software like Reaper
