free, are under linux, and pro;
damn good though design starts to date, easy to use.
reliable if properly configured,
no graphical user interface (ugly).
requires one of the wings ChamSys to work well because not compatible with generic MIDI controller.
the wings are also ChamSys node 1/2/4 universe, and a trackball (generic) for the positions of cars can be connected by usb only if you use one of the wing ChamSys.
(Otherwise node works with generic usb ENTTEC Pro, in simplified mode)
usable with a free node Enttec, but limited. for the Pro, see the aquisition of a wing ChamSys.
I work with this system for a year and a half! It's very intuitive, and the big advantage is that it's a carbon copy of the console.
Basically it's a mix between Grandma and Wholehog. For me it's more of a console dedicated to automatic! The environment is completely malleable.
We work as he wants.
I find it more intuitive than Grandma and the Wholehog and easier to work on it in live host.
In addition, the price / quality ratio is very good.
