I don't know about the BCF2000 , but to record the slider movements you have to enable WRITE LATCH as well as depress the TOUCH Button ( the same one with the drop down for write latch, etc)

Then you get a crosshairs in the sliders.

Eventually found on the web a suggestion that worked and in case its useful for others

After Starting BCF2000 whilst holding the 4th top row button and then Exit on BCF,
Launch Vegas preferences and Start the set-up within VP Midi and External control Tabs
Yes use latch etc...
The last trick i found is what makes it write ( you may have to press "V" first
Is on the BCF 2000 Press Lower left on Encoder Groups
Along with Edit and it should work
