StepLoom
Beat maker & AUv3 groovebox
$4.99 · Designed for iPad. Not verified for macOS.
Build beats and shape complete song ideas with StepLoom: a touch-first groovebox with Timeline, Session, Flow, AUv3 instruments, MIDI, piano roll, and export.
StepLoom is a fast, touch-first electronic music sketchpad for making beats, loops, basslines, and melody ideas on iPhone and iPad. It gives you the focus of a compact groovebox without the weight of a full DAW, so you can start a rhythm, shape a synth line, try an AUv3 instrument, arrange patterns, and keep moving while the idea is fresh.
Create drum patterns with a step sequencer, write melodic parts with piano-roll style editing, stack chords, add legato, adjust BPM, mix tracks, and switch sounds. Turn loops into songs with three complementary arrangement views: shape clips on the Timeline, launch quantized Patterns and Scenes in Session, or build visual paths and probability rules in Flow. When you want to go beyond the built-in sounds, add AUv3 instrument or effect plugins, choose exposed plugin presets, and activate Plugin Sound directly from the sound picker.
StepLoom is built for quick electronic music drafts: open the app, tap a grid, hear the result, and turn a loop into a structured idea.
