Try each program first
Each download is the demo and the full program in one. Enter your license key, and the demo becomes the full version, with nothing to download again. The demo never expires.
PianoFlex
A complete piano to play and shape, as a program of its own and as a VST®3 plugin.
System requirements: Windows 10 and 11, 64-bit; a 64-bit processor with 4 cores or more; 4 GB of memory; 100 MB of disk space.
Each download is a Windows Installer (.msi) file. It installs for you alone, with no administrator prompt. If you tried an earlier preview, uninstall it first.
What the demo leaves out
- PianoFlex: 8 keys are silent, whatever plays them, and in what you record, render or export. They're grayed on its keyboard.
- ComposerFlex: songs play in full through PianoFlex Player. What it sends to a MIDI port leaves out the same keys, and songs aren't kept as MIDI files. The Song Library works in full.
- Both: a session lasts 20 minutes. Start the program again, or reload the PianoFlex plugin in your DAW, for another 20.
Everything else works in the demo, saving your own presets included. PianoFlex Player, which comes with ComposerFlex, is free and plays every key.
