That is, if you programmed all the top row encoders to be CC7 on channel 3 then you will get this effect.
It is because of the excellent part of the BCR that allows for external control (ie change Live on the PC and the BC keeps in sync).
To stop it, just reprogram the encoders to a different Midi message (eg CC type or channel)
Glad you sorted it out.
Feel free to pop over to Mark's forum as I am ( and I suspect Mark is ) not here very often.
All the best
