Flowr - MIDI Chord Controller

Baltic Digital

About this app

Flowr transforms your Android device into an expressive MIDI chord controller. Sketch ideas, perform live, or control hardware synths — Flowr puts a complete chord palette at your fingertips.

A smarter, more affordable alternative to hardware chord controllers — instant download, no waiting, no shipping.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
SONGWRITER MODE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Write chord progressions using scale degrees (I–vii). Petal colours shape each chord. Inner petals add voice-led voicings for smooth, professional progressions. Use the quality toggle to flip major and minor instantly.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
THE PETAL WHEEL
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

At Flowr's heart is the Petal Wheel — a circle of fifths that makes key selection intuitive. Tap or slide to change keys instantly. Choose between:

- Classic Circle of Fifths — Outer ring for major keys, inner ring for relative minors
- Parallel Layout — Major and minor versions of the same root

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
9 CHORD PADS WITH XY CONTROL
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Each pad triggers a chord in your selected key. Drag your finger across any pad to send MIDI CC messages — a chord pad and XY expression controller in one.

Chord types include major, minor, 7th, maj7, m7, 9th, sus2, sus4, add9 and m(add9). Change keys while holding a chord — Flowr automatically re-triggers the new voicing.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
GYROSCOPE MIDI
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Tilt your device to send continuous MIDI CC data. Control filter cutoff, reverb depth, or any parameter — just by moving your phone. Three axes, three assignable CCs.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
USB MIDI & INTER-APP MIDI
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

★ USB MIDI — Connect to hardware synths, audio interfaces, DAWs and computers
★ Inter-App MIDI — Control Android music apps like FL Studio Mobile, Caustic and G-Stomper

Flowr appears as a MIDI device automatically. No complex setup required.
