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 sequences. No loops. A generative synth that plays on by your rules. And you can play right along. Key, scale, density, complexity — just set the rules, and five machines (arpeggios, bass, drums and a sampler) keep playing, with a different phrase every time. What you shape is not a song — it is a way of sounding. No AI picks the notes: your rules and probability do. Move a slider and the sound changes shape without ever stopping. Density, contour, filter, tape movement. It is built so that nothing you touch can break it. Then play right along with your own fingers. The on-screen key pad holds only the notes of the current scale, so nothing goes off-key. Play ARP A, ARP B, BASS or DRUMS, or connect a MIDI keyboard. What you play can be captured into the looper. ■ Five machines • ARP A / ARP B — two independent arpeggio engines. Ten arpeggio types, including Phrase (builds melodies) and Fingerpick (fingerstyle guitar) • BASS — a dedicated bass engine (STEP / COMPLEXITY / OMIT / PATTERN) • DRUMS — a drum machine built from probabilities (KICK / SNARE / HIHAT / NOISE) • SAMPLE — record one bar, slice it, rearrange it • Chord progressions (presets / automatic / 16 custom slots), ten time signatures, six LFOs ■ 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 64 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; play ARP A, ARP B, BASS or DRUMS • PEDAL (sustain) and a one-bar looper that records how hard you played and transposes with the chords • MIDI keyboard input (ARP A / ARP B / BASS; damper pedal, pitch bend, standard control changes) • XY pad and performance FX that work only while held ■ Sound (11 voices) • Piano — three velocity layers, stereo, damper release • Electric piano — harmonics shift with how hard you strike • Nylon-string guitar — synthesised with a physical string model • Marimba, kalimba, handpan and chime — struck instruments, measured from the real ones and synthesised • Waveforms (sine / triangle / saw / square) plus an acid filter • Filter, ADSR, five drive types, tremolo — shaped per voice • Delay, reverb, Glitch, Granular • 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, as an effect, and as a MIDI effect • Ableton Link, MIDI Clock, MIDI out (ARP A / ARP B / BASS / DRUMS), LFOs and XY as MIDI CC • External audio input (line / microphone) • Background playback — keeps playing when you switch to another app (iPhone / iPad) • WAV recording and export One-time purchase.
