So I'm wanting to build a project that will let me control a series of switches from my computer. I've managed similar things before but the new things in this project that I'm unsure about are:
-
MIDI over USB
I know the newer Arduinos have a programmable interface that can 'pretend' to be things. Can this be used to be a class compliant MIDI device? As in, I plug the USB cable in and it gets auto recognized as a MIDI device (rather than needing to use serial I/O). -
Relay/Transistor switching
My technical knowledge isn't great when it comes to this. Basically I want to bridge connections in an audio circuit. Not audio signals but sort of repatching the guts of it. It's this circuit:

All the funny plus/cross things are the contact points that I'd be repatching.
It does this:
So what I want to do is make those connections, but from my computer.
What I'm unsure about is wether it can happen with transistor switching, or an IC switch, or relay.
Any input/thoughts would be appreciated.
