    MIDI2DMX

    It is simple, and the DMX side of things could definitely be done on an ATMEGA328. The less simple part would be programming the usb device type to show up as usb-midi (as opposed to simply using an FTDI usb interface). Showing up as a class compliant usb midi device is a critical component to the project - and that makes it worth using a Teensy. (The Teensy has a programmable USB device type.) The HW midi part would work fine - but USB midi is important. That said - the project is on github and I would welcome improvements / collaboration / issues / pull requests etc

    Hmm - you could use it with that, but you would need to do some additional work. This is meant for DMX controlled lights - so you would need to build a dmx controller for the ws2812. It's not a normal analog controlled LED - the ws2812 has a microcontroller attached to each led that needs PWM to control it. Some good details on the ws2812 are here: https://learn.sparkfun.com/tutorials/ws2812-breako...You're also probably better off building a matrix with those (since they're individually addressable) - this project is more geared towards strips of leds that all behave as one, and have a DMX relay driving them.. or commercial lights with DMX interfaces. Per pixel control on a matrix is kind of a different beast.
