Yeah this does only have 9 banks of 4 if you use it in custom mode. If you use a lot of patches then this will be no good. You could use it as an 8 button footswitch though and have control over stomps A-D on the bottom and X-Reverb on the top?
At home I tend to live in browser mode and use Rig Manager a lot. The KPA sits on a desk next to my PC mouse so tweaking is easy. When I’m practicing for a gig I’ll use the foot controller, but the less stomps I have to make the better - so having control over 9 amps and 4 stomps on each is plenty for me ?
