right now, if some dev looks for "obxd source code," this is what they find: https://github.com/2DaT/Obxd

any idea if this is the right basis or not?


The version from discoDSP is here: https://github.com/reales/OB-Xd

and doing a diff between 2DaT git version and reales repository, I can see no change that would alter sounding, it's just skinning and the part of preset browser that change Banks.

Duplicating functionality already available is like the definition of wasting time.

The diference in sound does not come with the DiscoDSP version Vs lastest 2Dat version, but from an earlier 2Dat version to the lastest 2Dat

Yes, that seems the correct repository. Not sure if the old code is still there, and 2Dat seems to not be around anymore.

EDIT: The code there says "2DaT Better HQ mode" but is from 2014, so,. it must be from the version 1.1, which I believe is the one people refer when they say it's "better". Version 1.3 was compiled in 2016 <https://obxd.wordpress.com/category/news/> apparently from a different code ("Compiled using dozius fork and Soshi Studio GUI code"), which doesn't seem to be there in the repository.

I still have the old version from 2014. Will try to bounce the same track with the two versions and see how different they are. A little busy right now but I will try to find the time up to the weekend.

Nice!

So, probably the version with the filter that people talk about is the one before this commit on Oct 19, 2014, with the comment "Better 24db filter"

or before this one, from Oct 27, 2014 (Better HQ mode).

https://github.com/2DaT/Obxd/commit/5f8 ... diff=split

Sonically, the latest version of 2Dat (Better HQ mode) == discoDSP version.

...

or the version before Sep 16, 2014, with commit (Better 12 db filter).

https://github.com/2DaT/Obxd/commit/52a ... 274c2b260b

It's not hard to build it with current Juce Framework on Mac OS X, I build it some months ago (april), but it's needed Xcode installed and I removed Xcode from my computer.

If that's the case, I'm afraid I don't have it anymore, and the code doesn't seem to be available anymore either.

But I believe that the problem was introduced with the changes made to the code by Soshi, not by 2Dat. The last 2Dat version (version 1.1, I believe) don't have problems, AFAIK
