It's my first mono hardware synth and I love it. Every knob is on the panel, no menu diving here. The keyboard feels exceptionally good to play, I haven't played one that felt as good as these keys. The modulation system is a no brainer; press source button then your source - press destination button then your destination = Done! setting up modulations has never been easier and thats what we want. The unit is very well built and looks and feels amazing. It sounds like a Sequential hardware analog synth and not like anything else. Superb sounding Filters, the cream of the crop. The keys feel like the best I've ever played no joke. Sorry, I have nothing bad to say. I Love it.
