# MUSIC SEQUENCER by Darryl Sloan (30/11/2017)

# Step 1: press A to toggle the first note of the desired scale, then B to select.
# Step 2: press A to toggle the time signature (3/4, 4/4 or 5/4), then B to select.
# Step 3: press A to toggle the desired number of patterns (1 to 4), then B to select.
# Press A to move the range of notes selected. Press B to randomise the selected notes.
# The direction of tilt determines which scale the random notes conform to:
# Left = minor; right = major; forward = minor pentatonic; backward = major pentatonic.
# While holding A during the first note of the sequence, tilting up/down increases/decreases the tempo,
# tilting left/right selects a lower/higher octave.
