We officially support Ableton Live, Logic and FL Studio on Mac OS X 10.10 and higher.

On Windows, we support Ableton Live and FL Studio.

Studio One and Cubase are not supported yet.

Some other DAWs may work. You're covered by a 30-day money back guarantee if you want to try Captain with another DAW.

Captain Chords and Captain Play are available on both platforms. You'll be able to download them right away.

Captain Melody and Captain Deep are Mac-only at the moment, but the Windows version will come in a free update when they are ready.

There are 100+ custom sounds designed for Captain. You can use built-in Leads, Plucks, Basslines, Drum Kits, Pads, and more. All the sounds were sourced from Spotify Top 100 charts and Beatport Top 100 charts from different genres. It's a quick way to audition how your MIDI notes will sound with different instruments. You're welcome to use the sounds in your own productions.

Yes, you can route MIDI to your favorite VST synths. For example, you can use Captain with Serum, Massive, Sylenth, Kontakt patches, and every other VST installed on your computer.

You can also use your favorite external hardware, like Moog Synthesizers, Prophets, and anything else that supports the MIDI protocol.

You can use Captain plugins offline to play the MIDI you've already written. However, you need to be connected to the Internet to write new MIDI notes inside the plugins themselves. Our generators require Internet access.

So what happens when you're on a laptop, flying on an airplane? You can write MIDI notes inside Live and play them using Captain plugins, but you won't be able to generate a new chord progression using our User Interface. Internet is becoming common everywhere, even in the sky. Most studios have wifi. This requirement is usually not a problem.

The same people created all 3 products.

Mixed In Key was our first product. It's used by the world's top artists to analyze music and find the Key and Energy Level for every track, for perfect harmonic mixing.

Next, we created Odesi to help you sketch musical ideas, and write the core foundation of every track.

Captain Plugins are an evolution of Odesi. We took the technology inside Odesi and broke it apart into "modular" VSTs that you can add to individual MIDI channels. You can put Captain Chords on a new MIDI channel inside Ableton Live, Captain Melody on your Melody channel, and so on. Captain Plugins are like smaller versions of Odesi that run inside your favorite DAW like Ableton Live or Logic.
