Can you be more specific? I am not familiar with what the Mash button does. I saw a video where it seemed to do many different things depending on what delay algorithm was being used.
The Hot Switch will always quickly jump to whatever value it is assigned to. For example, if your mix setting is at 100, and you map the mix to Hot Switch 1 to be at 50, when you engage the Hot Switch you will see and hear the mix value immediately jump to 50.
