I can easily create 8-bit samples as I have a SBPro in a machine right behind 
me...  I can create 16-bit samples as well since I own a SB16 with ASP, but 
that card is in storage and would take a while to locate, as well as set up a 
386 box with windows, so hopefully there's not immediate demand for that.

If anyone wants samples, just let me know where to upload them.

An interesting principle of Creative's 8-bit ADPCM files is that the DSP on the 
original Sound Blaster was only fast enough to do compression/decompression no 
more than 12KHz.  So while you can artifically create files with higher rates 
(by patching the speed in the .VOC file), they play back at 12KHz.
