Appreciate that.I'm not measuring any additional gaps.
The next release will only do the slow bypass when bypassing/engaging. During channel/scene changes the bypass/engage will be normal speed. This will prevent any funkiness during channel/scene changes.
I could swear that the Filter blocks could change channels while a chord rings out and have zero gaps. Is this something that changed along the way? I have been using Filter blocks for pre and post volume and EQ tweaks for ever. Maybe I wasn't changing channels?
