Bc2000 (for the BCF2000 & BCR2000)

I feel dumb asking this... but a newbie's gotta learn somewhere... :)

I am looking to purchase a BCR2000 and polyevolver rack (which I found for a great deal).  But want control.  Thus I found some of the evolver patches here which look great!

But, I was wondering how the LEDs interact with say an evolver patch on the BCR2000.  If I switch or load a new preset on the evolver, do the LED's change to the new evolver preset settings or do the LED lights become 'dead' or return to zero value.

I currently use a monome and this is the case for some patches into DAWs because the DAW doesn't sent information to the monome without a seperate program to send the information (thus the use of python scripts).

If the LED light values return to zero, how does moving the knob work?  Does it cause the evolver's "parallel knob or effect within the synth" to go to zero then move in the direct moved by the BCR2000 knob; or does the "evolver internal effect" start moving from its last point?

Any help answering these basic question would be highly appreciated.  Thanks.
