Got my QC the other week and super happy with it so far. The only trouble I’ve really had is when building some of my own presets I occasionally find that some amp/effect blocks are greyed out when going to add/change a block. I’m sure there’s a good reason for it but I don’t understand why it’s happening or what I’m doing wrong? Anyone know or experienced it before? Cheers!

You’ve maxed out the CPU for that path. Continue the chain on another row.
