Converting a MIDI file to text (csv, tab-delimited, etc.) and back again?

[madscijr]

I could see these being a couple useful routines, and I even had (have? somewhere?) a couple ancient DOS EXEs that do it, but no source code and they may not work under modern Windows. If anyone has done this in QuickBasic or VB or a non-OO language like C, and would share your code, or even any experience with this, I would be willing to give it the old college try! :-D
