Hello cassp,
Here's a sample of a midi file that has a .wav file embedded into it. Instructions for inserting a .wav file can be found in the Calkwalk Help section.
It's rather large for dial-up users....Sorry. Almost 2 megs and it's only 5 seconds of sound.
http://genny.lib.umn.edu/sample.bun The extension on the file is .bun which stands for bundle or Calkwalk bundle in this case (midi bundled with audio). I suspect that only Calkwalk or Sonar can open this file but don't quote me on that. If you do have Calkwalk and you do open it you should see something like this:
Tracks 1-9 are midi data, track 11 is a stereo wav file embedded.
This snippet comes from a demo song on the Edirol SD-90 CD.
