Re: missing first note during loop playback of midi file
MIDI is not sound. It is a sequence of commands that tell a synthesizer to play notes. Each MIDI note should have (at least) two commands - a "note on" message and a "note off" message.
If the loop does not start before the "note on" message, then the note will not be played.
