LoFi Jazz Generator vs ARPJAM Studio

Lofi Jazz Generator creates original smooth jazz, on demand. Every track is freshly composed — not streamed, not looped from a library. Just pure, procedurally generated music that breathes like the real thing. Inspired by the intimate warmth of Norah Jones, the soulful groove of Walter Wolfman Washington, and the modal elegance of David Gilmour, every session produces something genuinely new. WHAT MAKES IT DIFFERENT No two plays are identical. The generator composes original melodies, walking bass lines, jazz chord voicings, and brushed drum patterns in real time — drawn from jazz theory, not audio samples. Nine distinct chord progressions keep things harmonically interesting: - Classic ii–V–I and I–vi–ii–V turnarounds - iii–VI–ii–V and IV–iii–vi–V for soul and gospel flavor - A hypnotic Dorian modal vamp - The dark minor ii°–V–i - A bebop-flavored tritone substitution - And more CONTROLS THAT FEEL NATURAL - BPM slider — dial in anything from a slow late-night 60 to a brisk daytime 100 - Density slider — pull the music back to a few sparse, breathing notes, or push it forward into a fuller, busier texture - Mix sliders for Piano, Guitar, Bass, and Drums — shape the sound to your room and your mood - 8, 16, or 32-bar loops SAVE WHAT YOU LOVE When a seed catches your ear, star it. Your favorites are saved locally and ready to replay anytime — perfect for sharing a mood with family or rediscovering a session days later. SEED SYSTEM Every piece of music has a unique seed — a short code that recreates the exact same composition every time. Enter a word, a name, or any text to generate a specific piece, or go fully random and see where it lands. A Half-Eaten Toast creation. What's New: 1.0 - Initial release

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.
