I have the ********* BCR2000 controller and Novation Launchkey 61, both a which have a specific template in Studio One, but both of which don't function beyond 8 faders either. For live work I've used this with no problem - 8 channels were enough. In the studio though, I want to access all the channells I have. This is just not possible at the moment.
Either an update to the templates, or an allowance for the user to create their own template with a special feature to assign 2 buttons to moving the focus of the faders left or right by 8 would be tremendously useful for a much smoother work flow.
