Ok I'm not an audiofile..i'm a programmer that's done audio systems before, I am going to present you with a few GIGANTIC problems in what you're asking for since well I've faced them first hand.

1) MP3s don't support needle drop nativeley because of the way that the file is compressed, usualy in order to needledrop in an mp3 you haveto insert multiple headers. (yes i know you can set a time inside of an mp3 player such as winamp)
2) MP3 compression is kind of an iffy thing to work with in the first place if you want to operate on it.

So my first advice is to drop the 'mp3' part of that request, if you can that is, though I guess on the ipod it would be kind'a hard since it doesn't really play anything else (apple propriotary b/s doesn't count jsut like sonys ATRAC doesn't really count on the walkman players).

Anymatter, that's not the important part of this. Now i'mg going to give you some bad news. Real time mixing of files takes one of 3 things. One is a real time stich of the file into a single playable audio format before it is passed onto the audio buffer (which would take a pretty fast machine to do..and flattening sound never really sounds all that 'great'). Second is a multi-channel playing format where the player is playing multiple streams simultaniusly, as far as I know the ipods audio hardware does not support the playing of multiple streams simultaniusly). The third system is to be using multiple output devices/synths/etc and that has nothing to do with this topic lol.

So the short leg of this is, sadly, you can't really do it on the ipod due to its lack of strength...though you could 'fake' it possibly if you try hard enough.

Sorry if i sound so negative ;-)

I found a program that does everything you say heh. Oh well.
