Added secondary CC for extra controller and a Level CC control (stored), both with new settings for pinky key. New pinky settings: "EC2" sends on/off (127/0) for extra ctr CC2. "ECS" uses pinky key as switch between sending primary and secondary CC with extra controller. "LVL" lights up breath and portamento LEDs to indicate level (breath LED on full is max level, portamento LED full is min level), and level can be adjusted with K5 (up) and K1 (down). "LVP" is the same as "LVL", but with stored level transmitted at power up.
