“A software-sequencer controls 8 solenoids, that knock on different things and therefore produce some rhythmic noise. Made with puredata, an arduino board and a selfmade relayboard to control the solenoids.”
“Solenoid Drum Machine”
“Four “push” solenoids are driven through MIDI. Using a PIC 16F688 to receive MIDI via 6N139 opto-isolator. The solenoids are driven through TIP120 power transistors. The MIDI stream is being sent from REAPER running on a PC.
I will post more details in case you want to try to make one. I also hope to build on this and make it play something more interesting some time.”

“I'm using Ableton Live to send midi messages to Miditron.”
