Sound quality wise.....no. Ease of use, great fx included in them already, cpu friendly without costing too much, enjoyment of creating sounds with...yes. But in my opinion synths are overpriced if they are more than $50. Something like Kontakt is worth every penny they ask because the people recording those sounds know what they are doing. But synths....especially emulations...are not worth the money some of these companies ask for since so many others can emulate the same hardware synth and offer it free or for a little of nothing. So imagine if you had all of those hardware synths in your studio......would you really even care about virtual instruments? But the flip side of it is you would have to know how to use them.....how they work...becuse there are no presets for them.......(for example).
I think back to when I bought an ESQ from a pawn shop back in 95........those same type of sounds are being used heavy in music today. I spent $400 on the ESQ. Thinking about getting me one this year because I'm used to it plus I wasn't doing the computer thing back then....(hardly anybody else either).
Midi to usb.........is making my imagination run wild right now. Might even get an xr-20 so I feel like my old set up when I had a DR-5.
