We all know that SEM V2 and SEM V1 are essentially two individual synthesizers made by entirely different developer teams, each with their own GUI and tone characteristics.
Presets made on the V1 sound absolutely different on the V2
My personal opinion is that the first version of the SEM V was the best Arturia VST of the twenty-tens. It was actually one of the best VSTs of that era, period.
It certainly deserves to be ported to 64-bit Intel processors on the Mac
Arturia, please consider compiling a 64-bit version of the app, and perhaps even a native Apple Silicon edition of the original SEM V compatible with Big Sur
