I know, other synths like Serum, like Twin 3, like Dune 3 a.s.o. need also high CPU if you use many voices, it is common, but there is also a very nice sounding synthesizer which sounds very good, even comparable with The Legend or Diva in its sound quality (comparing videos on youtube are available), but maybe 10 times lower on CPU (or even more) with a unisono mode which doesnt need much CPU.
So why they get it done, but not other synths?
This is my questions and maybe also a feature request for Vita to improve the CPU usage.
