Give it the finger

Choose from 29 key and scale types and trigger chords with just one finger. From traditional triads to 6ths, 7ths or 9ths, right through to borrowed chords, suspended chords and more, Captain Play turbo-charges your MIDI keyboard.

Once you’ve chosen your key and scale, Captain Play fills each octave with the diatonic chords in the scale. That means it removes ‘out of scale’ chords, so you’ll never hit a duff chord. You can then customize the voicings and octave range to suit your playing style or song.

Stand and deliver

Captain Play runs as a standalone plugin and can connect to any software of hardware synth, so you can play chords on your chosen instrument. Alternatively, it comes with dozens of high-quality sounds, from guitars to basses, strings to pianos to awesome sounding synths.

Speed machine

Imagine trying to quickly and accurately perform complex chord progressions the traditional way. It would take years of practice, and at least a few takes to nail each recording.

With Captain Play, that’s no longer a hold-up. You can set your key and scale and get straight to work. Choose your voicing options, run the track and you’ll be jamming out great chord progressions in no time. From the simplest patterns to the most fiendishly complex, Captain Play will speed up your workflow.

David Guetta

“Captain can inspire you. I’m using it every day and showing my friends. Captain Melody is super convenient for songwriting. I love the color feature that tells you how stable the note is in the scale. It’s also cool to see what melodies are suggested when you are looking for a new idea.”

Laura Escudé
