Drumline

Drumline is a mobile app that lets Batucada bands create and use a shared rhythm library.
Leaders create rhythms (a looping base groove) and breaks using a MIDI-like step editor, map them to drum kits, and export everything as a portable rhythm Pack.
Band members load these packs on their phones and practice by looping the base rhythm while manually or randomly inserting breaks, all with tight timing and offline reliability for rehearsals.
