McDSP 6050 Ultimate Channel Strip Na

On paper, this is an excellent product, providing much of your audio track processing needs in one simple, CPU efficient, easy to set up plugin. I use it in Cubase Pro 9.5 to mix rock and metal music and find that the sound from all of the modules is very good.
However, it does have a few bugs which make its use extremely annoying; firstly, the meters on the compressor module are extremely unstable, showing a violent fluctuation of the gain reduction needle on the GUI's VU meter. I'm pretty sure that this is purely a graphical issue and has no effect on the sound output from the processor. I have tested this issue with a noise generator and against several other types/brands of compressor and can't detect any such rapid fluctuations in the levels.
Secondly, more worryingly, there are occasional glitches where the main input and output levels will clip, engaging the clip warning indicators. In one play-through of a mix, it will not happen, next play-through it will clip the master output. I monitored this very carefully, being meticulous to gain stage the audio levels passing through the plugin, but sadly, it happens at completely random times, almost like it momentarily stops working or adds a loud, undetectable low frequency signal that clips the meters.
Thirdly, there is no side chaining capability for the VST version of the plugin, which limits its usefulness greatly. A promised future update will apparently add this feature, but when this will happen is unclear.
Lastly, the VST version has no presets available, which is another feature the promised update to the plugin will cure.
On the plus side, the modules sound really good, all of them, I especially like the saturation modules which have a rich, highly tweakable convincing tub-like sound and the eq's are easy to dial in, each with a sound of its own! Which is what makes me so frustrated, I really want to like and use this plugin a lot, but the issues are spoiling my enjoyment of it!
I have written an email to the company, but as yet, I have had no response, which is also extremely annoying; this plugin is not cheap and I could do with some reassurance as to when (and IF) the VST version will be fixed. If ever it does and the issues above are cured, it will get a resounding Five Star score.
