The ports are well made in general, so good job with them! I found a couple oddities that would be cool if you fixed them, however:
- In the castle theme, the sitar should have a fast release (around $F3 should suffice), since it sounds quite weird to be all sustained.
- In the overworld theme, at the 1:02 mark, the trumpets are playing an extra note that should be played by the 'bah' voices, as Motament pointed out. You can just move the sample call a note back and lower the octave so it doesn't sound higher than it should.
Also, can you tone down the volume of the guitars in the star theme a bit? I feel like they're quite loud if you compare them with all the other channels.
While it's pretty faithful to the the actual music tracks in the game, although from the name, I was thinking that it would include all the tracks in the game, not just the basic songs. Do you plan to do more of them, actually?
If anything sounds missing it's bc I couldn't add anymore to it bc all channels were already playing something. This is especially potent in Overworld as it had a lot of percussion tracks, I couldn't put in the whole woodblock and tambourine track and had sacrificed the tambourine track to keep the kick and snare, even then I put the snare and kick together as a sample for that track as the 2 play together. Star theme same thing, etc. There's simply too much that'd play at times and I had to sacrifice, that's why those bahs are missing on Overworld.
