i would like to have the pbc connect to an expression pedal and then be able to have the pbc send any midi connected pedal a midi expression cc. This would be a device in the editor and could be set to control a different midi device expression (channel and cc) per preset. There would also be the possibility of assigning any IA button to control a specific pedal with the expression function. Also an IA button (or the same button) that scrolls through the different device expression control like preset up/down does currently. Not grouping but going through the list, I have seven devices that take midi expression. To really make it fun, the pbc could have sine, square, saw, random and more automatic modes to have the expression controlled automatically. This would be assigned per preset and also able to be selected/scrolled independently from another IA button.
