The problem I see with revamping Sonitus is that, it has already been done in many cases. I think the best thing would be to take the best of these devices and try and add all the various features to one device that does it all. A device that has real-time spectrum analysis, side chains, tons of presets, there are so many devices that only have a part of the whole picture. Make one mother of all l reverb units and incorporate the best features. One Reverb, One Eq and One Compressor, One stereo widener with several visualizations, One multi-band compressor, transient editor make them useable on both track and master bus. Rather than redundant products that each do different things, have one product for each that does everything and keep expanding on them with new iterations. I think of Wave brand plugins and they have so much redundancy and talk about old interfaces, most of the devices have no real-time spectrum analysis. Some multi-track visualizations with color taps for each track would be nice too.
The problems seems that just adding a giant reverb app would require adding a CPU and memory hog to each track.
Perhaps if there was a way to shut off main features so you only load the parts resident that you need might be a way of minimizing the load.
It is easy to get lost in a myriad of redundant plugins, we are better served by a focus on making certain plugins as full featured as possible while still keeping them modular.
A prime example are the two compressors in prochannel. Why two? It would be easy to combine all the features of both into one. Make the one switchable for mastering or tracking.
Furthermore, the prochannel EQ, why even have that when there is the LP EQ that is much more full featured? Make the LP EQ modular where you can shut off certain features so it can be used for both tracking or mastering. Then there is only one global EQ to worry about developing. Make it smart so if you insert it into a track it switches to simple mode and if you insert it into a master bus it switches to full-featured mode.
My point is cut out the redundancy.
Waves plugins are a prime example, how many different EQs and compressors do they have (over a thousand)? Do they really each have a different signature and colorization? Or is that just a bunch of hype and bragging rights? In my experience an EQ is an EQ. I might be wrong about this but a cheap EQ in the right hands with the right pair of ears can go a long way. Generally I rely on the spectrum analysis and my ears they all seem to do basically the same thing.
There are some plugins that have neat features so add them to the main plugin of this type. Stop making redundant plugins. Make a well focused and comprehensive suite to rule them all, build them into the prochannel.
