Easy way to create AAC's from midi's

Download midi files from any site, eg. www.ffmusic.net,
Download iTunes from www.iTunes.com for free,
click "file", then click "add file to library" and find the desired clip,
then right click and select "Convert selection to AAC on the file u want to change... It will take a 10-60 seconds usually and then there will be a duplicate file beneath it but the format is changed and the quality is now at 128 Kbps instead of 3...

pretty simple huh?

You're not really raising the bitrate. You cannot get more quality out of something.

But now, you can play your midi in aac players. Congratulations.
