A number of plugin developers seem to struggle getting their plugins to behave well in WaveLab. The fact that WaveLab is the only Steinberg product with Clip FX probably doesn’t help. I don’t think WaveLab is nearly as widely tested as Cubase and Nuendo by plugin developers. Whenever I decide to add a new plugin to my workflow, I put it through a few rendering tests to make sure what I’m hearing on playback is what I’m getting on rendering, and of course to make sure there are no crashes or GUI issues.
NUGEN has known about these WaveLab problems for a few years and it seems they are not doing much or anything about it.
It’s too bad because I like the analytical nature of NUGEN plugins, but I don’t have time to deal with the hassles I see in WaveLab.
