Thx, I've always run the two blocks in parallel! But always seemed to me that block b fx was not mixing with a they way I wanted. So, I put the routing in series way cooler!!!! it only took me several years to figure it out! I just don't really want to flip the block around!
You could always save it to another program number. Not to sound like a rep, but you're only limited by your imagination and willingness to experiment. Same applies to external routing. All the outputs are permanently active.
