Felt
Before you play

Tune-up

Connect your piano and run a quick sound check. Felt works with any acoustic or digital piano through the microphone, or with a MIDI keyboard over USB.

Tips for the microphone
  • Put your laptop or phone on the music stand, close to the strings.
  • Use headphones if you turn on accompaniment, so Felt doesn't hear its own speakers.
  • Chords are checked against the notes Felt expects — play them firmly and together.
  • Digital piano with USB? Use MIDI. It's perfect every time.
