The Full Experience
When a screen piano is enough
Not everything needs weighted keys. Checking a voicing, finding a reference note, or showing a scale to a room all work fine on glass.
Sampled, not synthesized
The piano and harpsichord come from a real soundfont, so a held chord decays like an instrument instead of humming like an oscillator.
Ten fingers, and it follows them
Every touch is tracked separately and slides as you move, so glissandi and full voicings work on a phone.
The same colors as every other tool
Keys light up by pitch class, so a voicing you work out here looks the same on the pitch graph.
