Alien Box can also run as a stand alone app adding effect to the audio input so you can play your guitar, bass or synth directly three the app if you have the connector to do so.

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. Add Sample tracks by importing audio or recording directly in the Tracks view, then use the waveform editor to trim, reverse, normalize, tune, and shape One-shot or Loop playback. The project Media Library keeps custom audio available for reuse and arrangement. Turn loops into songs with three complementary arrangement views: shape Patterns and audio clips on the Timeline, launch quantized Patterns and Scenes in Session, or build visual paths and probability rules in Flow. Draw or record automation for mixer controls and supported AUv3 parameters. When you want to go beyond the built-in sounds, add AUv3 instrument or effect plugins, choose exposed plugin presets, open compatible plugin interfaces, and activate Plugin Sound directly from the sound picker. Optional iCloud sync keeps compatible projects and project media available across your Apple devices. StepLoom continues to work locally when sync is disabled. 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. Main features: - Touch-friendly beat and melody workflow - Drum, melody, and custom Sample tracks - Step sequencer with playback highlight and loop control - Piano-roll style melody editing with chords and legato - Audio import and microphone sample recording - Waveform sample editor with trim, reverse, normalize, gain, tuning, One-shot, and Loop controls - Project Media Library for reusable custom audio - Timeline editing with drag, resize, layers, sections, loop ranges, and multi-selection - Quantized Pattern and Scene launching with Session performance recording - Blueprint-style Flow rules with Next, Jump, Random, Stop, and probability - AUv3 instrument and effect plugin slots - Plugin preset reading for AUv3s that expose factory presets - Plugin Sound option for playing tracks through AUv3 instruments - Mixer and AUv3 parameter automation - Mixer controls for volume, pan, EQ, filter, drive, meters, master gain, and limiter - MIDI input and external clock sync options - Optional iCloud project and media synchronization - Export full songs or the current pattern as audio, stems, or MIDI - Adaptive iPhone and iPad layouts StepLoom is for producers, beatmakers, songwriters, and electronic music learners who want a focused place to capture musical ideas before moving into a larger DAW.
