It's the MIDI Tonio builds when you skip importing a Source MIDI/KAR: no musical arrangement of its own, just your synchronized lyrics, chords and tempo, built to drive your keyboard's display while you play the song's real audio (MP3/WAV) alongside it โ including the SysEx command that starts both together on supported hardware.
None, if you choose WAV+CDG (or FLAC+CDG): Tonio imports your audio as WAV and never re-encodes it, so the exported file keeps exactly the quality you hear on SoundCloud. Only the MP3+CDG option applies standard MP3 compression to the final file.
