If you're using it in slave mode, those settings are done on the GT. For example, if you want to have specific effects turn on for the verse preset, you need to select the verse preset on the GT, then manually turn on the desired stomps on the GT. Finally, hold the IA Store button until it says "Stored" (3 seconds). It will remember those settings and recall them next time you select the verse preset. You can set up different effect selections for each GT preset that way.
One thing to note: if the button states seem to not be storing, check the following:
- Each button that controls a stomp slot needs to have the Send on Preset Change and Update on Preset Change checkboxes turned on.
- In the Devices tab, Send CCs on Preset Change needs to be turned on.
These should be set automatically, but if you start setting up in normal mode, set up your buttons, then switch to slave mode later, the settings will not all be correct.
