Shape the way you play.

Shape the attack, colour and sustain of your part with the instrument’s own controls.

The expression key

It articulates level, while ribbon response changes the initial approach to the target pitch.

Tone mixture

Tone settings and keyboard vibrato shape the line before it reaches the diffusers.

Diffuser colour

Diffuser selection and resonance change the colour and persistence of the response.

A countermelody that follows the song.

  1. Begin with one line

    Let a few notes answer the main theme.

  2. Compare the colours

    Keep the phrase unchanged while trying diffuser settings.

  3. Mark a transition

    Extend a note ending across a section change, then return to shorter articulation.

New demos coming soon.

The audio engines have been reworked. The previous recordings have been removed while their replacements are prepared.
