Let me try to explain this.
I bank up or down to my desired Performance.
Performance loads with Slot 3 rig selected.
Stomp (Mouse) is active in slot/rig and Tone setting is at 4.3
Slot 2 is selected.
Back to slot 3 and Stomp Tone setting changes to 8.7
Stomp Tone setting is only correct when performance is first loaded.
Once I change between rigs/slots in the same performance Stomp Tone settings change in every rig and stay that way until I bank up or down.
Does this make sense?
Can anyone help?
