4n25 arduino midi synth - 644db4de3505c40a0444
I\m using an Arduino Due board with an optocoupler 4N25 midi keyboard Arduino Yun and a synthesiser that can accept midi via usb. The problem is that the synth.

I have since come up with a better idea. Use an optocoupler to detect the negative voltage (say a 4N25). Tie the anode of the diode to.
The new sequencer for my modular synth is controlled by an Arduino (which I knocked up with a 4N25 found The Arduino MEGA is now running a MIDI to CV.
