Chord Organ (black panel)

tiny chord synthesizer (new firmware for radio music)

Chord Organ is a new firmware for the Music Thing Modular Radio Music module.
It gives the module a completely different function. Instead of playing samples from the SD card, it synthesises chords.

It's perfectly possible to create chords on a modular synth, but its a pain - lots of tuning and messing about. I wanted to create something as simple as a home organ with chord buttons. Chord Organ is exactly that; the top knob chooses a chord shape, the bottom a root note.

The full story of Chord Organ, including how it was inspired by a Bontempi Organ found in the street, is in this article over on Medium.

Chord Organ and Radio Music are identical modules; you can convert one to the other by installing new firmware over USB - details on how to install the firmware - and go back just as easily.

The top knob chooses the chord shape (Major, Minor, Drop 3 9th). The bottom knob chooses the root note. Both can be CV controlled.

The latest firmware now includes:
* A choice of 12 waveforms (the original just had four)
* Program chords by uploading MIDI files
* Easy to use configuration page.
* Alternative tuning support by dropping standard Scala files onto the SD card (installation details).
