How do  I get my JVM410H  to recognized channel changes via midi foot controller?

I've noticed that when switching channels, specifically from any other channel to the Clean channel in Green mode, I get an audible pop. Not like a firecracker going off, but definitely bothersome. If I set the Clean channel to Orange mode the pop does not happen. So, the pop only happens when switching to Clean/Green. This pop occurs when switching via the front panel buttons or my midi Voodoo Lab ground Control. 

I've had another JVM410H owner try to reproduce the issue, and they experienced the same pop when switching via the front panel buttons, but did not experience the pop when using the Marshall footswitch.

How can I correct this?

Hi! 

A newbie question here. Just bought the as50d amp and I'm a bit lost with the effects controls on it. So here's the thing that's bothering me, does the switches for channel one and two also control reverb or is reverb always on if the control nob is turned on of course. It is always on my amp if the nob is turned, even when non of the channel switches aren't pressed. Should it be like that that or is it something wrong with the amp? So should the channel switches next to chorus also turn on or off the reverb or not?
