Nocturne LoFi is an immersive generative LoFi and ambient music studio for focus, reading, rest, sleep, and late-night creativity. Choose a scene and let its beats, melodies, and environmental textures evolve in real time. Nocturne does not simply repeat one short recording, so each session feels familiar without sounding exactly the same. 【11 IMMERSIVE SCENES】 Travel from Rainy Desk, Late Night Study, Midnight Café, and Night Train to VHS Memory, Forest Cabin, Space Radio, Harbor Dawn, Sunday Morning, Thunderstorm, and Rainy Day. Every scene has its own musical structure and atmosphere. Shape mood, BPM, tone, space, motion, stereo width, and ambience, or generate a fresh variation. Save favorite combinations and return directly to their scenes in Immersive Mode. 【BUILD YOUR OWN SCENES】 Import audio into the shared library, stack up to three layers, and adjust each layer’s volume, pan, and playback speed. Blend your sounds with a generated Nocturne bed to create a personal atmosphere. Choose a built-in vector cover or import, crop, and preview your own image. Pick a clock position, then enjoy your custom scene alongside the built-in scenes on the Home screen and in Immersive Mode. 【SHIMMER AND SOUND SHAPING】 Built-in Shimmer adds a bright, floating upper tail to the sound. Control Amount, Pitch, Decay, Tone, and Modulation, then combine it with warmth, drift, reverb, and the rest of Nocturne’s sound controls. 【FOCUS, SLEEP, AND BACKGROUND PLAYBACK】 Choose a 25-minute focus session, 45-minute deep-work session, or 60-minute sleep timer. Timers continue on the Lock Screen and in the background, pause playback when complete, and gently fade the volume near the end of Sleep Mode. Control playback from the Lock Screen, Control Center, headphones, and Now Playing. Supported iPhone models also show playback and timer status in Dynamic Island, while the Home Screen widget keeps the current scene and BPM visible. 【AUv3 FOR MUSIC CREATORS】 Nocturne LoFi includes both an AUv3 instrument and the Nocturne LoFi FX audio effect for compatible hosts such as GarageBand and AUM. The instrument supports built-in scenes and shared user audio, MIDI performance, host sync, a variable-length step sequencer, swing, ties, per-step velocity, triplet rates, and host project state restoration. Nocturne LoFi FX processes host input with tape warmth, Drive, Tone, Tape Age, Wow, Flutter, Dust, stereo width, Shimmer, and a tempo-aware sequencer. It also supports automatable parameters and effect bypass. The standalone app can discover and load compatible third-party AUv3 effects—including their custom interfaces—so you can build an effects chain around Nocturne. 【EXPORT AND SHARE YOUR SOUND】 Render the current scene as a stereo M4A file, or add it directly to the shared AUv3 audio library for continued use in the instrument and your custom scenes. 【ONE PURCHASE, COMPLETE EXPERIENCE】 Nocturne LoFi is a one-time purchase with no subscription. One purchase unlocks every scene, generative music, custom scenes, timers, audio export, iCloud sync, and AUv3 features.

TraceSonic turns pictures into sound. Paint directly on a spectral canvas and hear each mark become part of a playable additive instrument: horizontal position is time, height is pitch, and brightness controls the level of each partial. Start with an empty canvas and draw with solid, soft, textured, tapered, or harmonic brushes. Fill the canvas with generated patterns, or import an image and turn its brightness into sound. Pitch snapping keeps freehand marks on your selected scale. Shape your sound with: • 128 additive oscillators spanning four octaves • Seven classic waveforms and 12 built-in wavetables • Forward, reverse, and ping-pong scanning • Adjustable pass length and tempo-synchronized loops in compatible Audio Unit hosts • MIDI note input for retuning the complete canvas • More than 60 factory patches, including tones, sequences, gestures, textures, drones, and sound effects • User patches that save the canvas and its synthesis settings • Solid, harmonic, soft, textured, and tapered brush families • Undo, redo, erasing, pitch snapping, and scale selection Use TraceSonic as a standalone instrument on iPhone, iPad, and Mac, or load its AUv3 instrument in a compatible host.
