Title: RailSegmentBrightnessPattern

Maps segments to notes starting at C1. Brightness is set by
velocity.

Hue is set by channel. Each channel has a default
base color set at the top of the sketch.

Notes C-1, C#-1, D-1 set the R, G, B values for the base
color of the channel. The velocity must be set greater
than zero to set the channel so you can't set all black.
