If the creation of a Stylophone iPhone app wasn't sacrilege enough for retro purists, noise experimentalist Jason has turned his 'mini organ' into a MIDI controller. Soldering iron, Miduino, Reason, etc…
"The technicals... Soldered wires to Stylophone PCB to use its keypad / resistor ladder… put 5V across it and read voltage at stylus by analog input pin on Arduino clone (Miduino). Found out input value for each note and sent out MIDI note on/off messages thru serial connection when notes are detected. Simple. Used Propellerhead's Reason to make the sounds," hotchk155.
