Neither do we still see what the "upper limit" is - it's a guessing game that I won't play along.
And this boils down to what you said:
You need to see how much work it can do.
If the "Guard Meter" is constantly at it's limit, even already "peaking red", I run into severe issues real soon. The CPU usage might not be high. But what does that help me if I have a suitable CPU (oversized even) if I run out of processing power within a short while and still didn't scratch 30% of my CPU. Should I just continue to "push more"? That's just stupid and totally lazy from sides of Steinberg. "This system is superior - it should work this way".
Not really!
In your case: 14-16 instances of FXpansions Strobe, and with merely 8 Instances of Prologue (which is elder than Strobe(!)). Some people don't even use "only" 4-5 Synths, but more. And on top of that, FX in real time.
You are lucky that your values are so low at 32samples!
The test project I got, with these values at 128 samples, I can add 3 more channels, then my stream shuts off. 4-5 if I use 256 samples. Do you think that is okay?
Again - if you like constantly running in the red, and you think that is correct - fine. But this is not(!!!) how it should work, neither how it should be.
To me, that is unacceptable. No reason to further debate this and "convince" me what I'm doing wrong, and that I need to accept this. Won't happen.
Period!
