Arranger Organ Keyboard

A real organ and a full arranger, in your hands

OrganKey turns your phone or tablet into an arranger organ. A tonewheel organ modelled in real time — drawbars, percussion, vibrato, a rotary speaker that speeds up and slows down like the real thing — with accompaniment styles that follow the chords you play.

Free to play. No account. iPhone, iPad and Android, in landscape.

OrganKey Home screen: voice Warm Drawbar, style Pop Ballad 1 at 80 BPM, arranger buttons Intro, Var A, Var B, Fill, Break and Ending, Auto Chord on, and a split on-screen keyboard with a chord zone and a melody zone

The organ

Not a piano with an organ sample

The tonewheel voice is synthesised note by note in a native audio engine, so every control changes the sound the way it does on a console organ — while you play.

9 drawbars from 16′ to 1′, each 0–8, for the classic registrations and your own.
Percussion — 2nd or 3rd harmonic, soft or normal, fast or slow decay.
Vibrato and chorus — V1, V2, V3 and C1, C2, C3.
Rotary speaker with slow, fast and stop — horn and drum ramp up and coast down with real inertia.
Drive, key click, leakage and reverb for anything from a clean jazz tone to a growling rock organ.

Organ Editor: nine drawbar sliders from 16 feet to 1 foot, percussion, vibrato and chorus selectors, rotary speaker set to slow, and drive, key click, leakage and reverb knobs

Organ voices

Every kind of organ, and only organs

The voice browser is organ-only by design. Pick a registration, try it in place, then shape it in the editor and save it as your own preset.

Tonewheel / Drawbar Pipe / Church Theatre Reed Combo / Transistor Electronic

Search, favourites, recents and My Presets keep the sounds you use most one tap away.

Organ Voice browser with categories Tonewheel, Combo, Pipe and Church, Theatre, Reed and Electronic, a grid of organ presets, and the details of Warm Drawbar

The arranger

A band that follows your left hand

Play a chord in the chord zone and drums, bass and harmony follow. Section changes land on the beat or the bar, the way an arranger keyboard player expects.

Intro, Variation A and B, Fill, Break and Ending — every style has all six.
21 styles across Pop, Ballad, Bolero, Rock, Jazz, Soul/Gospel, Dance, Latin, Worship and Asian.
Auto Chord with an adjustable split point, Sync Start and tempo control.

Style browser with categories from Pop to Asian, style cards such as Pop Ballad, Bolero Slow and Jazz Swing with tempo and time signature, and the six pattern parts of the selected style

Map sustain, expression, start/stop, fill, rotary slow/fast and variation switching to your foot pedals.

MIDI Learn

Move a knob or press a button on your controller and assign it to a control in the app. No mapping tables to type in.
