I had difficulty getting the .midi to work as far as sounding like your mix.
This is most likely my fault, I can’t seem to match any sounds to your .midi files on my end.
Long story short, would you be able to break the different sections into separate .flac files?
I can see potential for different video uses, one of which might require re-balancing the levels of each channel.
Anyway, something to consider, thank you :)
