I've never had a problem with this until today. I am using midi to switch presets with a Musicom EFX Mkiii+ and running it out of any loops between the controller and the amp. There is a full second delay between preset changes then the audio switches over. When I click my preset on the controller the display changes at the appropriate rate but there is audible dropout following it now, even when switching between the same presets. Frustrated, I updated the box with no change.
Help!!
