cont_frame(state, density)

assembles the frame for the cont-voice

• mark (special marker (crash, splash, etc))

generate()

high_low_seq()

creates a pattern consisting of the sequence of low-high changes

format to be defined

mark_frame(state, density)

assembles the frame for the mark-voice

push_value(val)

append a value to all keys of the pattern
