Sorry - I should have qualified my remarks about the Faderport. It does work - I just find the controls clunky. The transport controls are all click switches. Prior to using it I had the Yamaha 01x which has really nice soft switch transport controls, automated faders and a large jog shuttle. Unfortunately there are no 64bit drivers for it. The Faderport is also quirky if you load a project that was authored on a system with different midi device assignments. The project would freeze half way through loading, and the Faderport fader would stutter rapidly. Once you moved the fader, the project would continue to load, but the motorised fader would no longer function. I would have to correct the midi assignments, save the project, then remove and reinstall the Faderport under control surfaces in order for it to again utilise the motorised fader. It would seem the absent midi devices were causing a midi feedback loop on the Faderport channels. Not an issue if you always work on the one setup. I work on several so it was terribly annoying. I seem to recall that the driver installer was also clunky and convoluted. In my opinion not Presonus' finest hour.
In answer to your question aixmusajo, the Faderport is really just a glorified transport control. I always found it easier to navigate using a mouse rather than the small clunky buttons. Like any controller, it was great to be able to rewind, play etc, even when sonar was not the active window (for example, working on lyrics or a wrapped vsti or audio effect) It seems to have plenty of fans here though, so perhaps I have just been spoilt by the Yamaha 01x. As to whether the Behringer will be compatible, only time will tell. I can tell you that I am using a Behringer X32 on my live rig. It has an embedded control surface function that works just fine with Sonar. Being a secondary function, however, it's layout is not ideal. If it's drivers and build quality are anything to go by though, the xtouch should be rock solid.
