Virtual Organ — Hammond Drawbars & Pipe Stops
A free virtual organ with two authentic engines. The Hammond mode is a real tonewheel synth: nine working drawbars (16′–1′) with foldback, a physically-modelled Leslie rotary speaker (slow/fast with realistic spin-up inertia), single-trigger percussion, scanner vibrato and chorus, key-click and tube overdrive. The pipe mode is a church organ with principal, flute, reed and mixture stops by footage, a 16′ bourdon and pedal bass, tremulant and a long cathedral reverb. Play with your mouse, the computer keyboard, touch, or any MIDI keyboard, record your performance, and share a link that restores your exact registration.
How to play the organ
Choose Hammond for the drawbar/Leslie sound or Pipe organ for the church sound. The controls below swap to match.
Pull the drawbars (Hammond) or switch stops (pipe), or just tap a preset like Jazz, Gospel, Plenum or Tutti.
Click, tap, or use your computer keyboard — A–L are the white keys, W–P the sharps. Shift+← → moves an octave, Space holds sustain.
On Hammond, toggle the Leslie between Slow and Fast and listen to the rotor accelerate. Add percussion and a touch of vibrato.
Press “Connect MIDI” and pick your hardware. Notes and the sustain pedal work right away.
Hit Record, play, then download the audio — or press Share to copy a link that recreates your exact organ setup.

⌨️ Play by typing
The home row plays the white keys and the row above plays the black ones, laid out with the same geometry as a piano — A D G really is the shape of a C major chord. Reaches about an octave and a half at a time.
⇧ Black keys
Hold Shift and press a key to get the black key above it. Where there is none — after E and after B — nothing sounds: silence beats a wrong note.
↔ Move the octave
← and → move the part of the manual you type on. The bar under the keys shows how far your typing reaches.
🦶 Pedalboard
Switch on Bass split and the bottom row Z X C V B N M becomes the pedals — a bass line held under both hands. It borrows the last seven letters of the sheet layout.
🎹 MIDI keyboard
Plug one in and press Connect MIDI. Chrome and Edge support Web MIDI; Safari and Firefox do not.
🎚️ No touch dynamics
An organ sounds every note at the same strength however hard you press, so a computer keyboard gives up nothing here. Loudness comes from the Expression slider.
