Hex | Free Multi-track MIDI Sequencer

Hex | Free Multi-track MIDI Sequencer by Dynamic Tonality

Hex is a free multi-track MIDI sequencer that facilitates music composition in microtonal tunings. It integrates seamlessly with the DT-enabled synthesizers, or with any standard MIDI synthesizer. Moreover, it can also be used in conjunction with a digital audio workstation such as Pro Tools, Logic, Steinberg Cubase, Cockos Reaper, Ableton Live, Tracktion or Cakewalk SONAR.

Hex uses a lattice roll in place of the traditional piano roll. This enables unfamiliar microtonal scales to be intuitively visualized, and their tuning to be dynamically manipulated. The light buttons/lanes can be thought of as generalized “diatonic” notes, and the dark buttons/lanes as generalized “chromatic” notes.


1 – The hexagonal lattice represents the available notes, similar to a piano roll.
2 – Drag the tuning slider to transform the lattice and change the tuning.
3 – Click the tuning value, which displays the precise tuning in cents, to enter any exact value.
4 – Double-click in the envelope to insert a new node for automating changes to the tuning and lattice shear.
5 – The sequencer displays the notes of a sequence. Click inside a note lane and drag to the right to create a new note. Click and drag on top of a note to adjust its velocity, or on the right of a note to adjust its length.



Hex includes many features found in a standard MIDI sequencer, including:

  • Draw, edit and move notes with the mouse
  • Snap notes to beat lines
  • Multiple time signatures
  • Looping (Alt-click-drag along the timeline)
  • Unlimited undo/redo
  • Cut, copy, and paste commands
  • MIDI CC envelope sequencing
  • A metronome
  • The ability to tweak the colors of the interface
  • MIDI file export

As well as several novel features:

  • The ability to visualize and sequence dynamic tuning changes
  • Over 200 tuning presets
  • Several note layouts
