ARPJAM Studio vs Nocturne LoFi

No sequence. No play button needed. An instrument that keeps going without you programming anything. Two generative engines invent phrases endlessly inside the scale and chord you choose. What you shape is not a song — it is a way of sounding. Move a control and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. And you can play it. On the key pad or from a MIDI keyboard, right on top of the stream it is generating. What you play can be captured into the looper. Now your own sound can go in too. Record a bar into SAMPLE, the fifth machine, and chopping it up and rearranging it is the app's job. ■ Generate • Two independent arpeggio engines (waveform, filter, envelope, effects) • Eight arpeggio types, chord progressions, ten time signatures • BASS — a bass machine of its own (STEP / COMPLEXITY / OMIT / PATTERN) • Drum machine • Six LFOs, XY pad, performance FX ■ Slice (SAMPLE) • Record one bar from a mic or line input, with count-in and click • Record the app itself (ARP A / ARP B / drums), and overdub onto it • Load audio files — and the audio from a video file • Up to 32 slices, ordered by the same rules as the arps: direction, reverse, octave, probability, groove • STRETCH (on by default) — change tempo without changing pitch • Its own filter, envelope and delay / reverb sends ■ Play • On-screen key pad — always in scale • MIDI keyboard input (damper pedal, pitch bend, standard control changes) • One-bar looper that records how hard you played ■ Sound • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Kalimba, handpan and chime — struck metal, measured from the real instruments and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Delay, reverb, Glitch, Granular, overdrive • DRIFT / FLUTTER — tape movement on the synth voices and the live input alike • Concert pitch A=415–444 Hz ■ Connect • AUv3 plug-in — as an instrument and as an effect • Ableton Link, MIDI Clock, MIDI out • External audio input (line / microphone) • WAV recording and export One-time purchase.

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.
