Import/Export MIDI (I can do it; feedback needed)

[Starshine09]

I've coded some functions related to exporting MIDI (and VSQX for vocaloids!). It might make sense for me out also take input and output in Xenpaper script; likewise it might make sense for Xenpaper to be able to import and export as MIDI.

Should be easy to kill two birds with one stone, but I don't know quite how to go about that without rewriting the same code in two languages... is this program in JS? Mine is in Python (right now; I might start over in C because eventually the stuff I'm building on top of this has to be low-latency real-time)

Questions:

1. Is this worthwhile; would people want/use MIDI IO with Xenpaper?
2. How do I do an API such that Xenpaper could do either of two simple calls:
   [pseudocode]
   tunestar.xenpaperIO.MIDItoXPscript( [midi file object] )
   tunestar.xenpaperIO.XPscriptToMIDI( [string of XP script] )
