I forgot about NUGEN. I had some serious problems with them. Anything from opening a NUGEN GUI crashing WaveLab, to ISL2 rendering or recalling in it’s default state instead of the way I had it set.
I think some of that was resolved and if you open an old session with the updated version of ISL2, it gives you a warning that it couldn’t recall the old settings.
I’ll have to make sure I have the latest NUGEN updates installed and try again but NUGEN was basically unusable in the recent past.
