I’m struggling to get a footswitch to activate ‘next patch’ properly. I’m using an Arturia keylab 88 and have a Boss FS5U connected to the aux input.
I have no problem assigning the physical switch to the screen layout, and mapping the screen controller to ‘next patch’ at concert level. The issue is that it doesn’t work properly. When I press the switch the patch advances, but when I release it (and I can see the midi 0 is transmitted) it advances another 2 patches. I’ve tried all combinations of momentary/latching/reverse polarity etc, but it just won’t work.
What am I missing – something obvious probably.
