I bought a P6 on ebay for 400 bucks last week. (nice deal huh? 
) I needed to replace an aging Fatar keyboard, and am addicted to Cubase remote controls. I am also cheap so I only own a BCF2000 and a Korg nanonkontrol .
So far, this thing is really nice. The keyboard is very sensitive and is taking some time getting used to, but it seems more responsive than the Fatar SL880 (apples and oranges possibly since the Fatar has weighted keys and the P6 has sprung). I am able to play more expressively on the P6.
A post earlier in this thread mentioned that the remote did not sync to the the Cubase mixer visibility– this has been sorted and it works now.
edit: Actually I spoke too soon. It does not sync to visibility. All tracks have to be visible in the main console for the device to work properly.
All the insert plugins I have tried so far were already mapped. It has been pretty much working fine with whatever I try to do with it. A very nice experience so far.
Plus, the computer sees the P6 as an alphanumeric keyboard, and you can map buttons on the controller to send key commands to Cubase using the macro editor which you call up from the P6 and opens on the computer.
Another quite cool feature is that using the multiple ports Panorama presents in Cubase you can simultaneously have the dedicated Panorama device and a Generic Remote active. Cubase sees the Internal mode as a completely distinct device.
I like their approach. The only software is the Remote Device for Cubase and their drivers. There is no wrapping of VSTs a la Automap, and you can fall back on the so-called internal mode to send whatever might not be included in the dedicated Cubase modes
As far as support goes, I installed the software on the 24th, and Cubase was crashing with their remote device actve. On Dec. 25 they posted an updater that fixed the problem. (If indeed it wasn’t user error, heh). But they posted an update on Christmas. Can’t complain about that, eh?
