Always great to see someone pick up music porting! Your ports aren't that bad at all considering how long you've been porting, either. I haven't heard the original for the first and last of those songs, but I do like the @3 scaling up and down in the background of the last song, and think that aside from percussion being a little weird, it's probably the most complete (err if that's the word) of all your ports here.

Seeing Airman ga Taosenai as one of your "first ports" and having what's there turn out decent is rather impressive. I hope you can add in the missing parts (I don't think I hear percussion, for instance) when you shrink down the insert size. I love that song.

Here are a few tips to help you improve them:

- For ones where you have notes at very high octaves like your third port here, I would recommend lowering the volume for those notes so they don't become dominating, or at worst, ear-burning to listen to.

- For longer songs like Airman ga Taosenai, if you find that the song is extremely large even when it is looped the best it can be, and would rather have a reasonable insert size for use in the hack over the whole song, listen closely for an appropriate point where you can refer it back to an earlier part of the song without there being noticable difference for that connection so that you can abridge it smoothly.

- When dealing with percussion, try swapping instrument between drums. For example, you may find that all the f+ are hi-hats in the midi, so stick @22 before f+, and all the e notes may be powerful, loud drums, so @29 for those.

You can host the text files on a freewebs or put them on pastebin. I might help you loop some stuff if you need it. I hope to see you continue porting and become exceptional in it, and congratulations on making these. You are off to a good start. :>
