If not Sequential is required then you'd need a fully programmable controller if you want to put the 4 patches in a row on the board. Otherwise you'd have to do a lot of tap dancing switching banks. If you put them in a row a simple dual foot switch could index the 11R up and down utilizing the 1/4 control input. No midi required. I have a fcb1010 with uno firmware but as I understand the last Behringer firmware can do it too. Peak makes a smaller programmable midi controller. I've thought of downsizing a bit to a Rocktron midi mate. I like 2 rows of switches so I can turn fx on and off and have a gain boost programmed too.
