I am using the latest beta and have a line 6 m5 in a stereo loop in the mod slot. When engaging the loop for the first time in a rig I get a surge in volume which then drops down to the standard level. This does not happen again when engaging the loop unless I change rig where it happens again the first time I activate the loop. This occurs whether the pedal is bypassed or not and on both clean and distorted rigs.
Any help would be appreciated, is this a known issue?
