Ok, I just committed the libgig changes for writing gig extension files (SVN
r3474). Please review and test them, because most nostably I do not have any
gigs with extension files so I cannot test it, and I am also missing some
knowledge about the new chunks (see below).
No problem. I'll do this this evening.
Also note in DLS.cpp, where it is now automatically creating the 'doxf' chunk
if missing, I was assuming a chunk size of 148 bytes. Is that correct?
Yes that's exactly right. 4 byte int containing '99', string zero padded
to 128 bytes and 16 byte dlsid.
And I also figured out now what this ominous ".gx99" file is about: that's for
writing convolution effect data (a.k.a. GigaPulse). So now that makes more
sense why that is always handled separately as .gx99.
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.
So I would suggest simply adding two checkboxes to gigedit's file format
dialog:
- "Large File Support" (default on)
- "GigaStudio Legacy Extension Files" (default off)
That makes sense. I'll do that.
Thanks for your patch Ivan!
You're more than welcome!

All the best,
