Study Singing

Open Free Tools is a free open-source music tools community. We are starting with MIDI Piano Trainer and an experimental Audio-to-MIDI converter: upload MIDI files, practice with falling notes, test piano audio conversion, and help improve the project with real feedback.

This server is for musicians, piano learners, MIDI users, developers, and open-source builders. Audio-to-MIDI is still beta, so feedback about wrong notes, timing, tempo, and bad conversions is especially welcome.

English-first. Core tools stay free.
