Play with expression

Everything a chord controller should do, in the device already in your pocket.

Play chords instantly

Select any key on the petal wheel. Nine chord pads give you triads, sevenths, sus chords and more — all perfectly voiced and ready to trigger.

Expressive XY control

Every pad is a canvas. Drag your finger to send continuous MIDI CC data. Modulate filters, control vibrato, shape your sound in real time.

Tilt to modulate

Enable gyroscope mode and your phone becomes a motion controller. Subtle tilts send MIDI data to any parameter you choose.

True circle of fifths

Navigate harmony the way musicians think. Relative minors sit inside their majors. Moving between keys feels natural, not mathematical.

USB MIDI. No latency.

Connect directly to your DAW, hardware synth, or groovebox. No Bluetooth lag. No audio interface needed. Just plug in and play.

“I built Flowr because I wanted to play chords expressively — not just trigger them. Every touch should mean something.”

— Daniel Cotugno-Cregin, creator

In the studio

Sketch chord progressions faster than clicking in a piano roll. Use XY control to automate filter sweeps as you play.

Live performance

Flowr fits in your pocket. Pull it out, plug in, and add expressive chord pads to any setup.

Sound design

Assign gyroscope axes to synth parameters. Move your phone to explore timbres you'd never find with a mouse.
