Update:
I think I've cracked the format.
There are still two weird issues with reading & writing it properly
but I believe I now completely understand the header.
I've updated my notes page, and my sox hack.
I also put up a VERY small example sound file:
http://www.slinkp.com/linux/more.zip
That contains an .aif sample which I then imported on the SU and
generated an .ssp sample. Comparing them byte-by-byte in emacs hexl
mode was very instructive.
The remaining issues:
1) given a pair of samples (not bytes - samples!), the SU700 switches
them.
I have no idea why. But it's definitely doing it.
2) Rather than interleaving stereo data, each channel is written to a
separate chunk.
I need to figure out how to get SoX to write that...
But I'm going out of town for a few days and won't have the sampler
with me, so I can't do anything else till next week.
