Watch the video: Create and modify chord progressions using Captain Chords

Write chord progressions in any Key and Scale. Captain Chords will help you build your own chord progression from scratch, and discover the sound of different chords.

You can automatically Minimize the Leap, choose inversions, add 7th, 9th or suspended chords. You can add passing chords, and add more complexity to each chord by adding more notes.

Build a groove

Instead of playing basic chords, you can apply rhythm to your chord progressions. There are 100+ rhythms in Captain Chords. Some are basic (like "play on the Offbeats"), and some are super hard to play for experienced musicians. We included both types so you can compare simple rhythms with complex ones.

To create our exclusive rhythms, we analyzed hundreds of famous tracks. There are some rhythms that were used in numerous #1 hits because they sound great. We aren't going to tell you what they are, but we included them in Captain Chords. Try to find them. The goal is to get you inspired and help you play a better chord progression.


Use built-in sounds

There are Leads, Keys, Basslines, Pads, Guitars, and so much more. It helps you work faster when you can hear your Chord Progression played using different instruments.


Jam live on your computer keyboard

The "Clip Jam" mode is amazing. Press the "A" key on your keyboard and you'll hear the first chord of the scale. Press the "S" key, and you'll hear the 2nd chord of the scale. Your entire keyboard becomes musical.

Captain Chords is intelligent enough to use correct voice leading, and minimize the leap between the chords.

If you come from an MPC background and you like playing drums, this is going to feel amazing. Every time you hit a button, you'll hear a perfect chord.


Route your MIDI notes to Serum, Kontakt, Massive, Sylenth, and more

You can route the MIDI output from Captain Chords into Serum, Sylenth, Massive, Kontakt, Spire, Atmosphere, and all other VSTs and AUs.

You’ll see the notes inside Captain Chords, but you’ll hear the audio coming from your favorite synth.

Connect your analog gear

Route the output from Captain Chords into your hardware. That way, you can focus on sound design while Captain Chords is playing your custom chord progression.

Buy Odesi + Captain Plugins for Mac


You can use Ableton Live, Logic, and other DAWs that support VST and AU plugins.

Yes, we are working on it. Our Mac code is written in Objective-C and Cocoa, and our Windows code is written using WPF and C#. Those are different programming languages, and it takes extra time to make a "native" version of the plugin for Windows. We plan to release it sometime in 2018.

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 Hook 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.
