For example, David Guetta wrote the melody and chords for this remix using Captain Chords and Captain Melody.

With Captain Melody 3.0 you’ll gain access to 6 songwriting tools that are unlike anything else on the market.

Beta-tested by David Guetta

Captain Melody is made by musicians for top artists just like you. We love receiving feedback from everyone.

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.

Melody writing is easier when it fits the harmony. We thought about that, and made these plugins great at getting along with each other.

Smart Pencil and Paintbrush for MIDI

Reshape your Melodies DNA

Now it’s getting really crazy, by using the Lanes tab within the Idea Tool you can reshape the very fabric of your melodies. Focusing on different intervals throughout a melody can emphasizes and highlight different emotions. Find your own personal way of communicating sadness, joy, and happiness.

Melody 3.0 includes a randomization button. You can click it any time to try out a randomly generated version of your current selection. It’s an amazing way to fast-track inspiration.

Yes. Make a rhythm you like, select all notes, and click “Root” magic button inside the “Move” tool. This will reset the pitch of all notes to play along with your chords. This is identical to the old Captain Deep’s “Follow the Chords” tool.

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.
