Can I upload the sheet music I already have?

Yes. MusicXML and MIDI open directly; printed PDF scores are converted with music recognition.

Does it listen through the microphone?

No. To check what you play, connect a MIDI keyboard and use Wait mode (Chrome or Edge).

Partly free. The core features and the free pieces are free to use. A few extras, such as the high-quality piano and medley mode, come with Pro — see "Basic vs Pro" above for every difference.

Piano: Soloist

A flowkey alternative: Piano: Soloist

flowkey is a popular subscription app with structured piano courses and a large library of arranged songs, with videos of a pianist's hands, a synced score and a Wait mode that listens through the microphone or a MIDI keyboard. Piano: Soloist is not a lesson course. It is a tool for playing any score you already have — your own MusicXML, MIDI or PDF — with falling notes, the highlighted score, slow-down, one-hand view and MIDI-keyboard Wait mode, with no subscription.
