Piano software for Windows
ComposerFlex writes complete solo-piano songs from its own musical rules and plays them as it writes. PianoFlex is a modeled piano: every note is calculated as you play, with no samples. ComposerFlex plays straight into PianoFlex, and PianoFlex also works on its own.
Pick a style, press Start, and hear a new piece: melody, left hand, chords, form and dynamics. Like it? Its seed brings it back exactly.
No samples to load. Every note is computed as you play, so there are no velocity layers to jump between and no loops to hear.
How they work
No AI model makes the music or the sound. The programs do it themselves, on your computer.
ComposerFlex composes the way a musician does: from rules of harmony, melody, rhythm and form, tuned by ear.
PianoFlex models the hammer striking the strings, the soundboard, the dampers and pedals, the microphones and the room, note by note.
ComposerFlex plays straight into PianoFlex on the same PC, with no driver. PianoFlex also works on its own with any MIDI keyboard or DAW.
Try before you buy
One download is both the demo and the full program. The demo plays fully, with no noise or muted notes, for 20 minutes at a time; restart it for another 20. A license key lifts the 20-minute limit and unlocks saving finished work.
No strings attached
