Since buying this I've used it a lot for sound design. It fits in nicely with workflowand it's great to have a synth-style filter that's easily usable for non-synth inputs. I've used it on already existing tracks, connected it up to my microbrute and also my electric violin.
It's packed with useful features, the envelope generator works well on either the main sound source (great at detecting peaks) and I especially like the side-chain input where I can feed in an existing track to drive the syntyh output. I got some great synthetic drum sounds from a Doepfer Dark Energy using this. I haven't yet used the CV/Gate input but I imagine that's equally useful. And it has sample-and-hold too, lovely for getting those stranger noises and, in one case, an ostinato!
The quality of sound is excellent, as you would expect, with very low noise levels even on quiet inputs.
The build qulity is good, the dials and switchs feel solid to use and stay where they're put and theo whole box feels good but not over-heavy.
This is my first Vermona unit and I'm seriously looking at getting more in the future.
