Hmmm, I own multiple Dave Smith Synthesizers...
I'm pretty darn sure he wouldn't make a "Weak Sounding Synth" whether Digital or Analogue.
Dave Smith is great, he pushes boundaries. He knows what analog can do, he also knows analog has limitations (technology and price) so he creates instruments like the Evolver
that really shine showing how Digital and Analog can come together and showcase both of their strengths.
Anyone who says digital is weak or not as good as analog doesn't understand there really is no comparison. They're different tools for different jobs, they aren't in the perpetual competition so many try to put them in.
Also the Prophet 08's oscillators are all Digitally Controlled Analog Oscillators.
