Thank You Jos, Yes thats the Idea. A VSL User is in the Situation have one of the best Library, but it also needs alot of Attention and Mixing Skills. To me Its not easy to mix 2 or 3 Flutes and Piccolo, I see this here on the Polkas but also on other Mockups.
I use only MIRx Konzerthaus (and Im happy for this One Slider Solution). Its sound better than what I tried with Vienna Suite Hybrid Reverb, but ofcourse this has Potential too
I now often mix in Mono. The Idea is when all Instruments stacked on each other I hear which Instrument is too loud in Relation to another Instrument.
I often use the Highest Instrument a Flute and Bass , this is my Reference Point to mix the other Instruments in. But this Reference Point also change when different instruments play the Lead Melody.
