No problem. I'll do this this evening.

Yes that's exactly right. 4 byte int containing '99', string zero padded 
to 128 bytes and 16 byte dlsid.

That's great! I think this means that the string in the 'doxf' chunk 
might actually be an impulse name. I wonder also if the .gx99 file is 
just a RIFF file with a .gsi (Gigastudio Impulse) file embedded in it? I 
have several of both of these types of file to hand so I'll try to 
figure out if this is the case. It would be nice to know the .gsi file 
structure also in order to add reverb at some point in the future.

That makes sense. I'll do that.
