I was thinking about this as well. I was also searching if I could leverage my FBV Shortboard MkII (via .fbv preset) to control/switch effects and access all 12 presets for live performance. Maybe an FBV preset already exists for the Catalyst and I haven't found it yet. So far, an iPad can be leveraged to call up one of the 12 presets via midi connection using an app that lets you call up patches via midi message but I would like to use my feet.
Thank you in advance!
