Hi Graham,
that's great.
By the way, just in case you weren't aware,
if you have the "Single Touch" button flashing, your STS's will change with each variation
ie press vari 1 = sts 1
Vari 2 = sts 2.
I have the 5 switch pedal board and I've assigned one of the pedals vari up, another vari down. Haven't quite worked out my optimum settings for each of the pedals yet, but that's a handy one.

best wishes
Rikki
