I use some analog gear on about 80% of projects but even on those, it would be nice to do things like automate the threshold of a limiter, de-esser, or maybe automate a few EQ frequency or gain changes. Maybe this is part of why I do my analog processing in REAPER and not WaveLab but even with projects heavy on analog processing, I will still do the final limiting in WaveLab where automation of limiter threshold would be nice. Then of course, projects that are all “in the box” in WaveLab it would be very nice to have some parameter automation instead of just a wet/dry blend.
That being said, not a lot of plugin developers support WaveLab officially. Many just test Cubase and assume it’s good enough for WaveLab too (which it’s not), so it’s hard to say how reliable the automation will be during playback and rendering in WaveLab. I’ve finally got all the plugins I normally use to be stable on WaveLab 9.5, no GUI issues, no crashes during rendering, or absent processing on rendering. I’m not sure if I have it in me to go through another round of testing all of them for plugin automation accuracy in all scenarios.
