Hey, person above! ^^ thanx a ton for your overview of what I hope will be a fun synth that is not too hard on my cpu. I like some complicated synths that allow you to truly modulate the sounds via envelopes, other waves, and etc., but I also love easy to use synths that actually have GOOD sounding (not too generic) pre-sets, because they really allow one to spend less time programming, and more time being a musician! So, thanks, I'm downloading this now for FL studio.

Even now, after many years, Abakos still stands out. In my top 15 free synths.
