[QUOTE="AudioApe, post: 1625241, member: 321801"] As Dave stated, MIDI data is not audio data. MIDI data is a set of instructions which tells each synth module, or software synth, what note to play, for how long, how loudly, and on what instrument (among other things.) Your app probably saves in either it's own format or as a General MIDI file, which is readable by any sequencing app. The General MIDI format includes the specification that all GM modules map the same instrument (sound) to the same location. Thus, a note on command to patch #1 will play an acoustic grand piano note on any synth. I can only guess that converting a GM file to compressed audio relies upon "playing" the sequence and converting the audio data created by the synth module to the chosen format. I'm afraid that doing this in reverse would be like trying to create a multi-track recording from a two-track master. [/QUOTE]
