This version avoids the nasty breakup and now hard-locks every lead note to the selected key/mode. The new Human Listening slider makes Auto Solo remember the last phrase, answer the groove, vary little motifs, leave breathing room, and build ideas. New rule: solos do not overlap unless they are intentionally making a harmony line or a chord. The backing groove is protected from slider changes, menu changes, randomize, recording, solo buttons, and solo errors. Only Stop shuts off drums, bass, and keys. Only you can turn Auto Solo off.
