Pretty good port! I would've used @15 instead of @1 for the BAHs, but it's not major. Not super accurate as MP pointed out, but sounds SMW-ish enough. (Feel free to update the port when you can.)
Not sure why you decided to use #optimized but it doesn't sound weird so thanks for the extra ARAM space!!
changed @6 bass for @4, since it can handle lower notes better.
removed Channel #0 beginning notes, since it sounds bad and isnt even at the original thing,
changed volumes for channel #3 and #4 a bit.
I might change something else in future, but for now that's it
@MercuryPenny: You dont need to worry much about it, since it's to look SMW-ish guess @5 do nice, about the wrong notes, I cant do much since I dont have an accurate midi for it, and also, I tried myself to make it sound like the original by ear, since midi's chords are pretty wrong, nothing is perfect, but can get better with time.
I appreciate the feedback
there's dissonance everywhere and the instrumentation is pretty weak. it could really benefit if those @13 chords could be completely redone because honestly they aren't working, but they're far from the only wrong notes here (the bass in the second half is also pretty bad, and the @14 towards the beginning has a few bad notes too). @5 is not a good acoustic guitar, i'd say that @1 adsr you used for the BAHs would work better for that than @5.
