I don't think you guys completely get how IT, XM, and MOD files work. If you realized it I think you would never bother with using another method again (that is if you're on a 56k modem like me and need a way to make your songs take up the least space as possible). In these files you put in pre-existing samples that you create, like the guitars of a song. You make one good catchy melody for your guitar that is about 5 seconds long. Ok, you make a drumbeat that is 5 seconds long. You do a bass tune that is 5 seconds long. You create a loop for them (within the sound file so it's stored data. If you take it to another tracker program it knows where the loop is located). Your actual song is going to be 10 minutes long.

Ok, it's 10 minutes long. Man, file is going to be about 10 megs. That will take almost 30 minutes to upload or download on my internet connection! Yeah, if it was an MP3 but these are MOD files. What a MOD file does is that it stores the samples only and your musical note instructions with its database style interface. What does that mean? There is really only 15 seconds of real sound data in a mod file. Do you catch what I'm saying? That means the file is more like 500k to 1 meg. If you go crazy you can get them up to 2 megs with really long guitar solos added.

It's just more efficient and you can transfer your completed songs faster than you ever could with an MP3 or WAV file. I need to see what Pro Tools is but I'm pretty sure its output is either going to be MP3 or WAV.
