Colorduino HELP

Hello!

Ive managed to get the SetPixel code to work (in a way).
Im ham-fistedly trying to make the thing go bananas with bad mathematics.

I have some questions.

  1. Can I use the Colorduino alongside an Arduino to control the LED matrix according to data from sensors.
    a) one major concern is that, for the program I want to run in paralel, I need the serial comm pins on the arduino for MIDI output.

Thank again for all your help
