Hey, that's good, I'd like to do those things as well.

You mean getting it to match the standard, or encapsulating it in the most 
convenient way?

I'd like it to be generic enough that the code could be re-used to 
transform live MIDI streams as well.

I think a few of us are interested, but we may not have the time to 
contribute much.  I did get half way through converting my old C++ code, 
but I don't think it's really good enough for anybody else to work with.  
Unless you want an example of something that can read and write the files 
successfully.

Where?
