Use Music Templates

Hexachords propose 4 «basic» music templates to help you to pre-select a musical environment:

  • Orchestral
  • Piano
  • Pop-Rock
  • Strings
  • Electro
  • Ambient

The templates provide a list of default instruments and select the AI engine accordingly.

Experiment with New Music Ideas Quickly

Drag and drop the music blocks along the timeline of each sequence of your song (introduction, theme, variations, transitions, end, etc.) to create the complete structure of your composition. You can include as many blocks as you want without restriction. Each block can be independent from the others. Orb Composer also provides blocks variations implementation.

This allows to resume a main theme in different possible ways:

  • In a more intense or less intense version.
  • With an instrument with a different melody.
  • By integrating a variation.
  • By simply copying the theme.

Block Scheme

The complete structure of the song is permanently visible in the top menu. To add a block, just click a + button or drag and drop a block from the Blocks tab. To navigate in this structure, click on the block on which you want to work, the interface of Orb Composer will then refocus on this block.

Create a Musical Structure Precisely

Attach a structure type to each music block with a simple drag and drop. Orb composer embeds a list of possible structures, containing sentences such as:

  • Standard
  • Answer
  • Question
  • Answer Prime
  • Answer based on question.

Use Chord Progressions

Orb composer also embeds a library of chord progressions that you can enrich. You can create new chord progressions by modifying the existing ones and saving them. Any type of chord progressions can be created. Try and experiment new ones as much as you want. Find quickly the chord progression you need with a simple search tool. Chord progressions can be filtered by specifying a key, a number of chords or both. You can associate the chord progressions to different moods so that they can be filtered by mood.

Use the Huge Chords Database

Highlighted keys remind you notes of the chord you have selected.

Friendly Workspace

Orb Composer has been made to allow you to use it easily, the interface is clear, simple and all main functionalities are reachable from here. In one window, you can see the clips, the options and all the main features without going on fastidious submenus.

What you can do in the block area:

  • Draw curves
  • Manually create your instrument clips
  • Import Midi Melody
  • Create own Chords
  • Create Chord Progressions
  • BPM

Different Bar Items

For each music block, pick a bar item, representing the block’s structure with the musical phrases and the bars symmetry. It can be set very easily in order to create complex or simple music structures.


You can draw curves of “momentum” and “intensity”. For orchestration, you have an additional “Space” parameter. Momentum is related to the horizontal density of notes. Space is related to the number of instruments playing at the same time. Intensity is a complex high-level parameter which depends on each instrument/articulation combination, dynamics, register and polyphony.

As Density increases or decreases the number of notes per bar. Higher density results in more notes per bar. Lower density results in fewer notes per bar.

Time Signature

You can use the following time signatures: 4/4, 3/4, 2/4, 5/4, 6/4, 5/8, 6/8, 7/8, 9/8, 12/8.

Import Melody

For block item, you can import your own melody (MIDI format).

Chord Progressions

Create as many chord progressions as you want or use the chord progressions library, organized in moods.


Each clip represents a little music segment played by a unique combination instrument/articulation. All the fine-tuning parameters are available per clip, which gives you an infinite amount of tuning.


  • Creation of instrument clips: Create, delete and edit easily your clips. 
  • BPM: Pick the BPM you want. 
  • Tonality/Mode: Set the tonality you want, with full mode control, including music modes.

  • Magic Chords: creates new block’s chords 
  • Magic Notes: recreates the notes with the exact same clip parameters 
  • Magic All in One: recreates everything above in 1 click

  • Articulation
  • Role

  • Rhythm
  • Register
  • Polyphony
  • Different chord notes

Clips can be locked for safety, and can be moved on other instrument or theme structure.
