TrioSonata transforms MIDI files into printed scores and accompaniments for solo or group performances. Working in conjunction with MIDI Doctor, TrioSonata can grab a MIDI file from the Internet and do the following: 1) separate the musical data into solo and accompaniment parts, 2) change the range and key to match your instrument, 3) create a printed score for the solo part and 4) play the accompaniment on a computer or keyboard with measure synchronization and an optional metronome.

There are thousands of MIDI files available for download on the Internet, and most of them have at least one problem. MIDI Doctor has five main functions: 1) quickly make custom settings like channel voices (instrumentation), 2) delete unwanted or unnecessary information following your specifications, 3) correct the order of MIDI messages and store files in a standard Type 1 format 4) remove selected channels (e.g., delete the solo part to make an accompaniment) and 5) transpose the key signature or note range.
