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 a rhythm 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. PROGRAM ON THE CONSOLE Tap any of the 16 step cells across the eight girder lanes to place a striped block. Press and hold a step to dial in its velocity, chance and flam, so repeated bars swing instead of sounding mechanical. Tap tempo, 40–240 BPM, a swing amount, a count-in bar and a click or CoreHaptics metronome keep the groove steady. FINGER-DRUM ON VELOCITY PADS Eight pads read your touch position for accents, with hold-to-choke and a roll gesture — play a fill by hand, then drop it straight into the pattern. FIVE SEEDED CONSTRUCTION KITS Night Shift, Steel Yard, Pile Driver, Demolition and Crane Yard. Each kit holds eight percussion sounds — pile-driver thuds, rivet snaps, girder clangs, siren stabs, gravel shakers and crane-hook clicks — 40 sounds in total. Every one is generated on device with AVAudioEngine oscillators and noise, so nothing is downloaded and no third-party samples are used. SHAPE EVERY LANE IN THE MIXER Level, pan, pitch, decay and tone sliders for each of the eight lanes, plus mute, solo and live level meters, so you can balance a busy tower without leaving the screen. ARRANGE IN BLUEPRINTS Chain patterns A–D into a Blueprint arrangement with per-slot repeat counts, then play the whole multi-bar song from start to finish. BOUNCE OFFLINE TO WAV Render your Blueprint offline to a WAV file and send it through the iOS share sheet or save it straight to Files — ready for a DAW, a lesson or a group chat. LEARN THE CRAFT Six hands-on Site Manual lessons cover step programming, swing, syncopation, dynamics, arrangement and export, with progress kept on your device. PRIVATE BY DESIGN No account, no network, no microphone, no ads and no in-app purchases. Your patterns and kits live in a local library on your device. Add the Tower Beat widget to the Home Screen to see the current pattern name and jump back into the Console with one tap. Whether you are learning rhythm for the first time or sketching an idea between sessions, Tower Beat Builder turns beat-making into something you can see: stack the blocks, watch the tower rise and hear the groove build.
