CO84 Synth
Our very own 80's analog synthesizer, built into the website. Just start playing: use your mouse, finger, computer keyboard or a MIDI keyboard. Pick a patch, or twist the knobs and make your own.
Sorry, this browser can't run the synth. Try the latest Chrome, Edge, Firefox or Safari.

How to Play
- Mouse or touch: click or tap the keys. Slide across them for a glissando. Click lower on a key to play it harder.
- Computer keyboard: the A to ' row plays the white keys and W E T Y U O P are the black keys. Z and X move the octave down and up.
- Higher and lower keys: hold the slide bar above the keyboard and drag it left or right (or swipe sideways with a trackpad), or use the Oct buttons. The keys settle on the nearest note when you let go.
- MIDI keyboard: plug it in, press Connect MIDI and allow access when your browser asks. (Browsers keep web pages silent until you have clicked or pressed something on them, so touch the page once first.) Keys, pitch bend, mod wheel (CC1), sustain pedal and program changes all work. Chrome, Edge and Opera support this; Safari doesn't yet.
- Wheels: drag the pitch wheel and it springs back to centre. The mod wheel adds vibrato and stays where you leave it.
- Your own sounds: turn the knobs (drag up and down, double-click to reset), then press Save to keep the patch on this device.
- Tempo: set the BPM and choose a note length on the Delay's Sync menu to get echoes that lock to the beat.
