-// Clock and drum pattern sketches for the Ardcore Expander
-// Feed a clock in "Clock in" for external beat. Set A1 to more than 0 for internal beat.
-// The clock in toggles between D0 and D1 to open and close.
-// Programs are set with A0. 1, 2, 3... etc from CCW to CW
-// 1. Cycle Program
-// 2. Halves Program
-// 3. Divider Program
-// 4. Drum Program Use A3 to set different drum patterns.
-// A2 controls probablility of output for triggers. Set A2 full CCW for no randomization and turn it CW for increased "drop out" of trig outs.
-// There is a 1 second signal as the program is changed.
