Tunody, ComposerFlex and PianoFlex

Three ways to create and play piano songs. Each is best at something different.

Tunody is the quick way in: free to create songs, for now, nothing to install, in your browser.
ComposerFlex is the one to build songs with: your own recipes, tempo, key and scale, songs up to 3 hours long, no limit on how many.
PianoFlex is the one to shape and play the piano: sliders for the sound, your own presets, live playing, and any MIDI file.
