  1. I didn't really enjoy this one, and personally I think most professional DAW's will provide much better solutions (or so one may hope ;-)).

    My main gripes with this one is that it looks and feels too plain. Yes, it may have a nice color scheme, that's not what matters. All the basic interface provides is a way to stretch the spectrum both horizontally or vertically. That's fun. But FAR from enough.

    When it comes to important settings, like changing the refresh rate things become a lot more tedious. Instead of providing a dial or something you have to click "settings" which, the horror…, pops up a new window right over your diagram.

    So, move that out of the way, then tweak the knob, then close the settings and you can go on. New signal? Open up settings, move the window out of the way, turn the knob… Yuck.

    The so called extra features do not weigh up against the cumbersome interface in my opinion.
