Ardio
Ardio is a MIDI synthesizer. It listens on all MIDI channels for regular MIDI data.
It is a 16 channel Arduino based audio device.
Software and schematics are designed by folkert@vanheusden.com. The PCB design is by Sebastius.
One arduino takes care of the MIDI processing, the other two get commands ("play a note on pin x, this frequency") via i2c.

notes
- Audio-out does not work with a headphone. You need to attach powered speakers to it. note 2026: this schematic needs an voltage following opamp
- You need to bridge the two capacitors in front of the jack-connector or else audio will be very soft. Also the most left resistor under the center arduino must be bridged instead.
