bankable mcu::volume ?

[simoniddqd]

How would you go about making mcu::volume bankable? I'd like to add a "next channel" and "previous channel" button switch to my project containing a PBPotentimeter for mcu::volume and a CCRotaryEncoder for vpot, thank you very much for this brilliant library. Edit: So I've found the mcu bank left and right, but somehow it doesn't work on this particular device I'm testing on. Must be some other command to "flip". Sending "channel_1" does work with volume for 1-8 but not for 9 and onwards.
