Also worth noting, at least on the rack version (cant comment on the stage) if you enabled/disable an FX then move to another slot using the cursor keys on the rack it retains the state of that FX slot (on/off) if you got back to it using the cursor keys. All without rig manager not being connected.
I forgot about this when i experienced this again the other day, whereas recalling another slot using the remote (or an external midi command) will restore its saved state and ignore those FX on/off alterations you made (unless of course you saved it as such)
