Yes; the RR uses 2 sets of controls for 4 channels of audio. The hardware all works on a "latch" type control, so when you move the fader when it's assigned to channel 3, it doesn't affect channel 1. But in order to then move channel 1 when you switch back, you need to move the fader to the position where the hardware was last in order to "pick up" the fader value to then make any changes.
