ComposerFlex and PianoFlex

Piano songs composed as you listen, and a piano you can shape.

ComposerFlex composes complete solo-piano songs from its own musical rules and plays each one as it writes it. PianoFlex is a complete, ready-to-play piano, with every part of its sound yours to shape.

ComposerFlex

Composes and plays solo-piano songs

Choose a preset, press Start, and hear a new song, its tune, accompaniment, chords and form composed as it plays. Like it? Its seed, kept with its preset, brings it back note for note in the same version of ComposerFlex.

  • 64 presets in 11 families, from Ragtime to Romantic Nocturne
  • Over 200 musical ingredients to mix presets of your own
  • Plays out of the box through PianoFlex Player, which comes with it

PianoFlex

Standalone piano and VST®3 plugin

Play it from a MIDI keyboard, from ComposerFlex, or in any DAW that hosts VST3 plugins, and shape every part of the sound while you play.

  • 33 built-in presets, from concert grand to upright and experimental
  • About 70 sliders for the hammers, strings, soundboard, mics and room
  • Records what you play and renders MIDI files to audio

How they work

Algorithmic, not AI.

No AI model makes the music or the sound. The programs do it themselves, on your computer.

Music from rules

ComposerFlex works from rules of harmony, melody, rhythm and form, tuned by ear, the way a musician composes.

Sound from modeling

PianoFlex computes each note from a model of the hammer, the strings, the soundboard, the dampers and the pedals, then places it in a room heard through microphones.

Made to work together

ComposerFlex plays straight into the PianoFlex program on the same PC, with nothing to set up. PianoFlex works on its own just as well.
