Just had to power up the unit to check this out...: 1. Bypass is configurable to one of three possible settings: a) when hitting bypass, the effect is turned off and the input is routed through to the output (just like when you set Mix=0%) b) when hitting bypass, the output of the effect engine is interrupted (instantly muting the delay). The dry signal is passed as set with the mix parameter. c) when hitting bypass, the input to the effect engine is interrupted (thus the delay "continues to ring"). There is no or only a very short interruption of the effect signal when switching patches (I didn't do any measurements, but to find this out you would have to record the audio and analyze it, as it's hard to tell when switching between patches which produce different levels to say if there was a minimum interruption. There are no clicks etc., and if there is an interruption, it is so short that it won't hurt except in some very special applications). The dry signal passes uninterrupted.
