Separate click and subdivision volumes • Count-in: a voice counts one or two bars before you start • Tap tempo to find the speed of any song • Practice timer: stops at the end of the bar when time is up SONGS (SETLISTS FOR DRUMMERS) • Lay out songs by section — intro, verse, chorus — each with its own bars, tempo, time signature and rhythm • An odd bar with an extra beat? Change the beats of that one bar. Pickups count in correctly • Free-time passage? Stop after a section and tap Continue to go on • Big section and bar display, with early warnings before changes • Chain up to 3 songs seamlessly; share songs with your band • Create: arrange chords and sections with drum and bass accompaniment; Write for Me drafts sections and chords from a key and style (Pro Lv2) • Standard: 3 songs, 12 sections each.
