I have the original B&W unit and I boosted it with the H3500 chips and that's the real value. That made me crazy about this hardware.
I miss these algorithms:
Patch Factory
Stutter
Timesqueeze
Dense Room
Vocoder
Multi-Shift
Band Delay
String Modeler
Phaser
Studio Sampler
Studio Sampler
Modfactory|One
Modfactory|Two
I did't hear much the mk2 so I cant tell about the sounding but anyway it is a very good plugin and i love it more with the new look of the mk2, its more transparent to look. I made comparison between the hardware and the mk1 version of the plugin and i was amazed about the similarity. Also I have a favourite preset on the hw (but I cant remember exactly yet) which is some kind of Haas pan with the ability to not just move the sound source left and right but in front and back too. I really miss that algorith from the plugin but the SP2016 plugin gives something like that, maybe when combined with the H3000 plugin.
P.s: The Omnipressor too, it's near the same as the original hardware. In that case I love the plugin better.
