Adjusted default breath cal offset value. Added inverted octave rollers option for NuEVI (EVR in fingering menu). Support for CME WIDI chip connected to Teensy underside pads. Alternate Serial2 TX pad 31 for separate MIDI output, jumper sensing between pads 27 and 28 and power control for WIDI using pad 33. The old "slow midi" function (touching pinky key when pressing enter to toggle on/off) now repurpused for WIDI power control (only available when pads 27 and 28 are bridged).
