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

“This is totally for me. I can take ideas that I play on violin, drop them into Captain Plugins, and come out with a super chordal sequence that I couldn’t come up with on my own.

Captain Plugins will take your music production to the next level.”


“I’m loving Captain Plugins and I used it on two tracks. It’s a super cool plugin. I just love that it promotes inspiration. It’s the perfect spot to get ideas going. I’m always looking for that spark of creativity and Captain always provides that!”

Ebonie Smith

“I love the Captain plugins by Mixed In Key. They really help facilitate programming in a streamlined way. I am able to produce quickly and efficiently while on-the-go.”

Chus and Ceballos

Morgan Page

“Captain Chords is an essential tool for modern composing. I love the new strum feature”

Rony Seikaly, Sugar Free Radio

Felix Cartal

“Captain Chords has become really valuable to me when I don’t have a MIDI keyboard handy. It allows me to build out interesting chord progressions quickly wherever I am with just my laptop. I love this tool because it shows me chord options I may have not thought of.”

David from Domino Saints

“For me, it’s all about the song. Finding the right chords and feeling is the most important part to making a smash track. Captain gives you the tools you need to push boundaries in your songwriting.”

Behind the Scenes wih DAVID GUETTA

We’ve done a huge amount of beta-testing on Captain Melody with David Guetta. He provided his comments and helped make the plugin better.

Edit Melodic Tension

You can edit MIDI notes inside the plugin. It’s like a mini-DAW running inside your DAW. You can edit your melody and see how it affects the harmonic tension with your chord progression created in Captain Chords.

Blue notes represent the most consonant chord tones, while green adds a bit more flavor and yellow provides the most tension. This x-ray vision into chord tension is a great way to develop your own musical palate and see what works best for you.

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.
