Sounds cool, but that's obviously not on the table. I think this is the domain 
of DAWs.

Fair point. But two comments:
- To get mp3 the MIDI is first converted to a lossless format anyway.
- I think many people who want audio files want them to *share* them, either on 
some sort of sharing platform or to hand them over to some partner for whatever 
purpose. And for that there may be specific requirements. 

But your comment reinforces my gut-feeling that the proper approach is not to 
provide too many formats but rather a nice, well-defined selection.
