still.synth
MIDI chord builder plugin
Two pads play a full chord, always in key. Add a bassline and drums, and it’s the whole band.
One minute, one take
A beat, a chord loop, a bass solo, then a melody on top. Every sound and every screen here is still.synth itself.
Live: play it right here
Two pads, one chord
Pick a shape, switch Rich or Bass, then tap a root to play. This is still.synth's own chord math in A minor, with sound. On a keyboard it’s the plugin’s layout: hold 1–8 for a shape, play roots on D F G H J K L ;
Everything on one panel
The Play tab holds what you touch during a take. Sound, key and mix sit one tab over.
- Layer switches: Rich, Bass, Drums, Smart, Melody
- Inversion and octave
- Looper: record, undo, stop, save
- Chord shapes
- Root pads, always in key
- Drag the take into your DAW as WAV or MIDI

Questions
What exactly is still.synth?
A MIDI instrument plugin and Standalone app for macOS and Windows that turns single-key playing into full chords with a matched bassline and drum pattern, quantized and recordable. Not a sample library: a live playing instrument.
Which formats and platforms?
macOS 11 and later (Universal: Apple Silicon and Intel) as VST3, AU and Standalone. Windows 10/11 (64-bit) as VST3 and Standalone. Your download page links both installers after purchase.
Do I need a MIDI keyboard?
No. Play from your computer keyboard: hold 1–8 for a chord shape and play roots on D F G H J K L ; — in the Standalone app and in the plugin while its window is in focus. A MIDI controller is fully supported too: map any pad, key or knob from the Mapping page.
Which DAWs does it work in?
Any macOS or Windows host that loads VST3 (and Audio Units on macOS): Logic Pro, Ableton Live, Cubase, Studio One, Bitwig, FL Studio, Reaper and others. The Standalone app needs no DAW.
Is it a subscription?
No. One payment, yours to keep. The current price is beta pricing and may change later; anyone who buys during beta keeps their license.
How do I get my license?
Automatically. Checkout runs on Stripe, and your key is generated and emailed within a minute of payment. See Delivery.
How many machines?
Three per license. Deactivating one machine frees its slot for another.
Can I get a refund?
It's a digital product delivered instantly, so sales are final. The Refund Policy covers the exceptions: duplicate charges, or a license that won't activate and support can't fix.
Where do my recordings go?
To your own disk, as a WAV and a Standard MIDI File. Nothing is uploaded; still.synth never sends your music anywhere.
