This a CV sequencer i built (with an arduino microcontroller). It Sequences the pulse width of my guitar through the Control Voltage input jack on the Pulsemonger pedal. I got the idea from tracking (composing) in famitracker, LSDJ and Goattracker. When you compose for the NES or the Gameboy, there are tons of effects you can choose from to make square waves more complex and interesting sounding – i always wanted to apply those effects to my guitar. So, once i saw that the Pulsemonger guitar pedal had a CV input for the pulsewidth i had to buy it. Sequencing the pulsewidth is one of the fundamental sounds of chiptune music – the ability to recreate this sound through my guitar was way too exciting. There are a couple reasons i built this with an arduino: I wanted to make it expandable and open source. In the future, I may add some tap tempo functionality or i thought maybe it might be fun to hook the sequencer up to my Gameboy (through the linker port) so the sequencing would happen in relation to the tempo of the song i’m playing.

Thanks to Vblank and Batsly Adams for their help. Vblank gave me some programming lessons and Batsly helped me choose the correct components to use.
