SL Tape 2.0 is an AUv3 cassette-style audio effect for music-making apps. Add saturation, tape hiss, pitch movement and wear to drums, vocals, samples and mixes. Six controls: - Drive: tape saturation - Noise: tape hiss - Wow: slow pitch movement - Flutter: faster pitch movement - Age: tape wear - Mix: blend original and processed audio Choose from 10 factory presets or save your own settings. Preset changes move the controls smoothly. The redesigned cassette interface includes animated reels, a layered mechanism and audio-responsive lighting. Use SL Tape as an AUv3 effect in a compatible host on iPhone or iPad. The standalone app does not automatically monitor the built-in microphone through the speaker.

About

Stochastic Lab

Features
Read full description

Stochastic Lab is a generative composition tool built around the mathematical methods Iannis Xenakis used to compose: probability distributions, stochastic processes, and Markov chains, applied directly to sound. GENERATE • 6 generation modes: melody, rhythm, cluster, cloud, pointillistic, sequence • 6 probability distributions: uniform, Gaussian, exponential, Cauchy, Poisson, linear decay • Full control over density, register, tempo, block length, and Markov-driven contour • Choose a single orchestral section (strings, winds, brass) or let the generator blend all three • Pick exactly which percussion sounds are in play REAL INSTRUMENTS • Real sampled strings (high & low), winds, brass, and an 8-piece percussion kit — not synthesized approximations • Authentic short (pizzicato/staccato) and sustained articulations • Genuine glissando and tremolo, generated as part of the composition itself EDIT & PERFORM • Full piano roll editor: drag notes, edit pitch by semitone, adjust duration and velocity • A live recording keyboard to play your own material into any layer • Freeze a generated block into a fixed, fully editable sequence at any time SCORE • A live, Xenakis-style graphic score (particle-cloud visualization) for every layer • Expand any layer — or the full combined score — to fullscreen, with zoom and a moving playhead • Export the score itself as a printable, shareable image SEQUENCE & ARRANGE • Multi-layer Sequencer for building full compositions from generated or recorded material • Song mode for arranging multiple sections into a complete piece EXPORT • Export audio (WAV) and MIDI, mixed or as separate stems per layer, straight from the Generator, Sequencer, or Song view AUv3 PLUGIN • Stochastic Lab also runs as a real Audio Unit (AUv3) instrument inside GarageBand, Logic, AUM, and other hosts • The actual generative engine runs live inside your DAW — not a static sample player • A dedicated on-plugin control panel (mode, distribution, density, pitch range, tempo, and more), with a Preview button to audition before recording • Full MIDI recording support, including pitch bend and glissando THEORY • A built-in Theory section covering Xenakis's life and stochastic music concepts, with real-instrument audio examples for every distribution Stochastic Lab works entirely on-device — no account, no internet connection required, no data collected.
