Demo— Watch Piano! in action
A complete walkthrough showing Piano!'s instant acoustic response, smooth note triggering, and clean interface on macOS.
“I built Piano! to have some fun, but also to solve one problem that I've been stumbling into for years: Every simple, easy, and fast Mac piano app never did everything I wanted and usually had problems, was outdated, was too complex, or was just slow and clunky.
Piano! is made to make piano playing on the Mac fun, simple, and instant, and best of all, headache free. Speaking of free: yeah it's free. I hope it makes idea generation easier and more fun.”
