MIDI + Filter Board

Pictures of a MIDI + filter board that I just prototyped are at http://tinyurl.com/yekmm7s The board has a MIDI in, MIDI out and four two-pole filters. The filters inputs connect to the DAC outputs of my NB1A board. I plan to use these to filter the waveforms generated by the NCO sketch (http://tinyurl.com/ydmz2su)
