/* proposed map
 
button1	picks what the selector switch rotates through. 
selector leds		selects	
--------------------------
0		temp br		voices
1		temp bg		filters
//2		temp bb		key - how do we know which key?

Also assign two midi notes to up key and down key in rotation

The tem led shows its color for 2 seconds then reverts to button 2 setting

button2
pots control as below

Button 2 maps the pots to their function
We do not jump immediatly to the pot value when changed
rather the pot has to move significantly before it takes effect after a switch
The rgb color combo indicates what the pots do

(which pot controls what)
