Ucannily interesting

A nice experiment in a more ambient kind of song. I think of it as a long dungeon-type of theme. Is that what you were going for? If so, i'd say you got it. If not, then it'd be great as a kind of cinematic song as well. The Melody is a bit simple and repetitive, but your mixing of various other instruments and beats in there helps to quell that slight annoyance. Overall, a good experimentation piece. If you can take the good from this song and apply it to other songs, you'll have a great track.

Well done! ^_^

Sweet

It sounds very nice. It's pretty ambient-like, what isn't my forte... Keeps repeating over time, what is sorta tiring. Even though, very good!
Looks like it would fit in an Ice Cave level on a platform Mario-ish game. Cool! ^_^

Haha, I suffer with that very same dilemma too... I've found that I'm able to save and load .MID files, though. All I have to do is convert the channels for MIDI and save. Later, I'll just need to load and change the channels back to whatever it were before!

Its alright

Try find yourself a full fruity loops or buy one =) Its seems jumbled, like ur, just as you say experimenting, and it doesn't really belong on here i dnt think.. but practice makes perfect yeah =) it sounds like the stuff that plays along with movies or somthing. Try listening to songs thinking about their song structures and seeing how stuff fits together. goodluck but theres alot of practice ahead of you =)
