I’ll look into that (and no, de-reverb is not using demucs).
Regarding the question of lack of GPU support at launch, it’s been answered here: SpectraLayers 10 - #63 by Robin_Lobel
Again, the plan is to add GPU support with patch 1 or 2. Even though it’s already working on my side, I really need to be sure it’s stable before releasing it, you can’t imagine the support nightmare and complains otherwise
