No OB and the latest OS. I Hade the same issue with the earlier OS.
The “faulty” sounds are always transposed a perfect fifth up.
Started erasing sounds because I thought that they where corrupted in some way, then I realized that there where to many and often really nice sounds.
I’ve seen this a lot with some of the presets (probably from sound packs).
I’m guessing it’s something to do with the operator ratios essentially transposing the patch. Easily fixed by transposing the track you’ve used that sound on to bring it to concert pitch. Although I tend to leave them as they are and see what happens when I layer on top with concert tuning can make for some interesting harmonies that I wouldn’t necessarily have come with myself…
Okey, wierd. It has been the same with the official sounds and soundpacks.
Can you save the tuning with a sound?
It´s a nice idea but then I need to transpose in my head when using other synths,
but it is easy to get stuck in common keys if something doesn´t force you to do otherwise.
I had this problem with some sounds too (from purchased sound packs). Really strange and kind of annoying. Obviously I can transpose the track, but had to remember which ones do that and which don’t.
