New Barton Musical Circuits BMC39 Step Rhythm Demo

Published on Feb 8, 2016 boogdish

"This is a demo for a new DIY synthesizer module design. If you're interested in building it for yourself, there are PCBs and PICs available at http://www.bartonmusicalcircuits.com/..."

"This is a step sequencer module. It has an internal clock with it's own output as well as two programmable output channels. It has EEPROM save/load function (saves patterns after powering down), and a range of 2 to 32 steps.
