larryfraz 9 Posted December 29, 2013 Author Share Posted December 29, 2013 This is a simple algorithmic synthesis MSP430 hack of the little Korg Monotron ribbon synth, using CV and gate from the Launchpad through a prototype board from the 43oh store. It receives midi clock and some controllers through uart and a standard midi input circuit and jack. CV output is boosted to about 5V with an op amp, no lowpass filtering done, the gate comes off the pin directly. Directions on hacking the Monotron itself are available from many sites. bluehash 1 Quote Link to post Share on other sites
bluehash 1,581 Posted December 30, 2013 Share Posted December 30, 2013 Looks pretty neat. I'm dumb on the MIDI side, hopefully @@RobG will appreciate this. Maybe explain like I'm five Also, add a link to this page from the POTM contest thread, so people know you have entered. larryfraz 1 Quote Link to post Share on other sites
abecedarian 330 Posted December 30, 2013 Share Posted December 30, 2013 Hmm... a new band- the B#5? B hash, B five, B hash five. Check out the new album available soon at Empire Records. dubnet, bluehash and spirilis 3 Quote Link to post Share on other sites
larryfraz 9 Posted December 30, 2013 Author Share Posted December 30, 2013 Check NatureTM's synth for the MIDI circuit: http://naturetm.com/?p=111 The opto-isolator is just in the MIDI spec to avoid ground loops... The MIDI hw and sw spec is at midi.org. Here is a good article on using midi clock ( with Arduino, but it seems to mostly focus on the midi) http://makezine.com/2008/06/03/arduino-basics-midi-clock/ Quote Link to post Share on other sites
