Right, I've remade Song 2 and it loads into SynthFont (the VST sequencer system I use) and it looks fine. I've not tried to play it yet, for reasons that will be clear.
The file shows as 11 tracks. Track 1 has very little in, re Tempo etc, this is normal.
The rest is as follows Tr 2 is set to Ch 3, Tr 3 is set to Ch 2, Tr 4 is set to Ch 1. The other tracks are set to Ch 0.
Tr 9, 10 and 11 just have some META (Text) items in, re credits, Dates, etc. No notes. Some of the tracks have a fair qty of Controllers, re sound mode, all look quite notmal.
Tr 4 is set to Celeste, all the rest are set to Acoustic Gnd Pno, but the file does make it clear that the instruments need resetting as you please. Tracks 2 to 5 contain extra PC (Program Change) commands, but these all reset AG Pno at present. I do not know what you were going to set these to? Any suggestions?
At the moment, the sound would prob be a mess. Seems to be orchestral in sound, no percussion, Ch 10 not used.
The music is showing as just under 2 minutes. I think one of the Tracks shows as near 400 notes, the others are less.
The file for Song 1 is a LOG bigger, but with a LOT more garbage, but I think that there is much more musical data as well. But a similar number of tracks.
How does this relate to what you are hoping is there?
