Tower Beat Builder

Tower Beat Builder is an offline, construction-themed beat studio for hobbyist beatmakers, mobile producers and music teachers who want to sketch rhythms in seconds. Every pattern is drawn as a rising tower: eight girder lanes are the floors, and each active 16th-note step stacks a black-and-yellow striped block onto its lane, so the groove literally builds upward while it plays. Five seeded kits contain 40 construction percussion sounds — pile-driver thuds, rivet snaps, girder clangs, siren stabs, gravel shakers and crane-hook clicks — all generated on device with AVAudioEngine oscillators and noise, so nothing is downloaded and no third-party samples are used. Users program on the Console, finger-drum on velocity pads, shape lanes in the Mixer, chain four patterns into a Blueprint arrangement, bounce the song to a WAV file offline, and learn the craft through six hands-on Site Manual lessons. No account, no network, no microphone, no in-app purchases.
