This is amazing. Probably the best synth I've ever used. For the first few days, I thought it was great but maybe slow to use, learning concepts/menus. After a couple of weeks (not that many hours, I don't have that much time!) I now find the workflow fast and making great sounds is fun and intuitive.

It is feature rich, hugely powerful and has a superb 'pure' sound. 'Analog' randomness/feel is easy to add with loads of options.

Very CPU efficient and stable.

I'm not quite as impressed with the presets as I don't think they demonstrate the power of this synth and they could be better organised. Due to this I probably wouldn't recommend the 'LE' version (which doesn't allow editing). As Melda updates are frequent, I'm sure this will be improved.

Stick with the interface, configure it to your liking and after a while you'll see why this is such a great VST. Definitely one of the very best available (maybe the best).
