Powering the board from just the MIDI cable is really neat!

Arduino based MIDI filter for quartertone keys and octave rounding. Detailed documentation (particularly on how to get the hardware and software to make the filter), and v1.0 release.

This is a midi filter hardware device.  It's just a simple Arduino Uno with a generic MIDI shield stacked on top (no solder setup), and this file uploaded into it:

https://github.com/rfielding/octaveRounder/blob/testable/octaveRounder.ino

It filters incoming MIDI and generates a quartertone flat lower half of the keyboard, does octave rounding, same note trill, and handles all of the bizarre corner cases in MIDI that occur on such a device.  (I have gotten a bit better at playing the quartertone section since this video, but this pedal is zero latency with solid timing.)

Arduino Laser dress.  Has since been redone to use the Mini Pro (a tiny microcontroller board).

Story
Tagline
Developer of: Mugician, Geo Synth, AlephOne, and Xstrument (aka Xtrument) music instrument apps.
Introduction
I used to play (left handed) guitar in a metal band when I was a teenager.  I'm a computer programmer doing user interfaces for security companies.  I create instruments, primarily for iPad/iPhone as my hobby now, looking to fundamentally alter the playability of this format and propel Mugician-like microtonal-capable instruments to replace guitars for a lot of purposes.  Google: Mugician, Geo Synth, Pythagoras, Xstrument, rrr00bb for more info.
