I recently bought Guitar Rig 7 and love the sounds. What I'm struggling with is how to switch its presets. In most guitar effect plugins there are 4-8 "slots" to hold presets that are then easily mapped to a midi foot controller. Why doesn't Guitar Rig have these? I have found a semi-complicated work around in Ableton building an effects rack, but would love to find a simpler solution in Guitar Rig. How can I identify 4 presents and map them directly to my midi foot controller? Do I have to use macros? If so, how? Thanks in advance for your help!
