7 things to know about Chord Organ
- 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.
- This video shows what you can do with a Chord Organ in a simple little case. Here the chord shape and root note are sequenced by an expanded Turing Machine and filtered through a God's Box Humpback Filter.
- 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:
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).
- A choice of 12 waveforms (the original just had four)
- There’s a long history of press-button-to-get-chord instruments; accordions, the Suzuki Omnichord, the Autoharp, or all those auto-accompaniment electronic keyboards that you used to see.
