CC#1 is not a modwheel CC. Rather the modwheel is usually assigned to 
send CC#1 data.

CC#1 controls modulation. Only modulation.If your modwheel is assigned 
to send CC#1 it will send modulation data. Only modulation data. 

The AN200 will respond to modulation data even if everything is zeroed 
out because the modulation data is coming from the controller.Hence 
the AN200 is not generating any modulation data but it is receiving 
modulation data, and therefore modulating.

To have the modwheel control something else, you have to change the 
default CC# for the modwheel.The AN200 should have a MIDI chart 
explaining what each CC# controls.
