Some musicians break the rules. Circle Guitar was built for them.
A guitar that strums itself. Freeing you
to express yourself in new ways.
A new way to play
“For me, as a musician, it’s about finding new sounds, and it’s about finding new ways of making sounds.”
Ed O’Brien, Radiohead
Circle began with a simple question: what would it sound like if a guitar strum never ended?
The answer changes how you play the guitar.
The wheel
A motor-controlled wheel carries picks, held in place by magnets. As it spins, they strike the strings.
Move the picks or change the speed, and the rhythm changes.
Fits the way you make music.
Circle Guitar sits in the space between an electric guitar and a digitally controlled instrument. At its simplest, the guitar’s own controls drive the wheel, and it plugs into a standard guitar rig.
At its most advanced, it is a guitar you can sequence, and MIDI gives the wheel precise acceleration and deceleration, for new kinds of guitar rhythm. Pedals and plug-ins can process its audio in time with the wheel.
You can, of course, play it like a normal guitar too.

Every Circle Guitar does all of this.
There are four options you can choose to control it.
The player
“I play guitar. I don’t want to program it.”
-
Standalone
- Encoder sets speed, start and stop
- Buttons set the speed, 1× to 6×
- Tap the Home button for a single turn, ending at Home
- A volume fader for each of the six strings
- Standard ¼-inch out, or a multichannel out with each string on its own channel
-
Pedalboard
With a Morningstar MC Pro
- Builds on Standalone
- Presets that change your effects, sweep the speed or set tap tempo
- Expression pedal acceleration
- Time-based effects synced to the wheel
- The guitar’s buttons become yours to map
The producer
“I sequence MIDI and work in a DAW.”
-
MIDI controller
Tested with BeatStep Pro. Others yet to be tested.
