Something global btw would be very cool!
stamkorg hasn't replied yet, so not certain if there's more info which could help understand requirements there better - but for sure, there are different cases for global vs. focussed edits.
I'm thinking in hindsight maybe the question may not be so much 'how can I decrease res in some detailed way' but like a general 'maybe it's too resonant overall, so can Pianoteq take that into account and reduce it generally in future updates' or something ? IDK - but for sure, there has been some interest in some top-level global tools for this kind of thing in the past on the forum.
a
in the past, various times, when others were not so keen on the EQ tools supplied, I (and maybe others before/since) suggested a simple 'tilt EQ' slider or knob (dark to bright).. it's something which is easily seen as a 'dumb' kind of thing, but I've mentioned before, you see it on mastering grade tools and it's not a toy thing for entry-level people struggling with more detailed EQ tools.. you get things where you want, then tilt a little to either side for a finishing touch... can be simple as any extra on the front interface (applied to final stage signal chain, nothing internal needs touching).
b
how about an 'applied resonances level' slider? (think of a higher up the tree 'sympathetic resonance' slider.. levelling not just symp res but the total of tools generating res).
To my way of thinking, those 2 things could give quite complete control to the many user issues/ideas which often come down to something like:
"How can I make [less bright] or [less resonant] without having to dig into many individual controls?"
In a way, the defaults are so good now, many don't necessarily wish to do fine edits, but rather some last mile 'negate some res' (instead of learning/tweaking the genuinely brilliant Res EQ and Res Dur tools).. or 'negate some brightness' without having to hone hammers and again facing some learning curves with the main Equalizer or the EQ3 tools.
Just because I love those tools in Pianoteq, doesn't mean that I'm in broad company there.. In my time I've noticed that a lot of users run screaming from anything to do with fussing with EQ - not just a Pianoteq thing, he adds again for old time's sake
