I bought Syntronik and it works well.
But it is a sample player with some editing capabilities. Arturia is a set of full synthesizer simulations.
With Syntronik when you open a Minimoog sound you can change some envelope and some filter settings.
With Arturia it is a full Minimoog simulation. So at the end I get more fun editing with Arturia.
I can also add that new synths (Synthmaster, MassiveX, Diva, Pigments) are much more flexible and powerful than a Minimoog.
Up to you, fun is anyway everywhere…
A sarcastic note: for me Rudess videos are totally useless. I cannot hear anything interesting. No music, no sound.
Only some very fast fingers.
