Virtual, variable resistors, with saved presets recallable by MIDI

Started mounting it inside the pedal tonight. Got far enough to do a test fit, and it fits great!

Obviously I still have the long wires attached I was using for the breadboard, and I'll shorten them for the final soldering; but I wanted to make sure I didn't need to make any further adjustments to the mounting points and routing inside.

I'll use the battery compartment for the PSU, MIDI serial bypass switch, and I plan to mount a RJ45 jack on the side for connecting to the breakout box. Looks like everything will fit!

The 1/8" jack is for the midi in (you only needs pins 4 and 5 from the midi cable for input), and I made sure the USB was accessible as well, so I can continue improving the code even after it's complete and functional.
