act imperative

Call and response. Takes the phrase the person just played or selected on the Melody track and writes an answering phrase in the following bars: same rhythm, moved through the key (echo, sequence, invert or contrast), landing on chord tones. Defaults to the last recorded take, then the selection. Returns a draft the person can hear and accept.
