Drone Meditations vs AumChord

A deep four-oscillator drone synthesizer for meditation, sound healing, and ambient composition. Inspired by Pauline Oliveros, Éliane Radigue, Stars of the Lid, William Basinski, and the long-form drone tradition. Real synthesis, real tuning systems, real cymatics — designed for listeners who want to go deep. Most "drone apps" give you a few sliders and call it ambient. Drone Meditations gives you a real instrument. SOUNDS YOU CAN SIT WITH FOR HOURS • Four oscillators per patch — sine, triangle, sawtooth, square, white / pink noise, granular pink, or loaded sample • Per-voice filter (LP / HP / BP), drive, cross-osc FM, stereo chorus, three-mode delay with musical timing, stereo Schroeder reverb • Twenty multi-target LFOs per patch (five per voice). LFOs 1–4 hit amp / pan / cutoff / Q / pitch / FM / FX-Mix; LFO 5 has its own row of granular + FX targets (grain, delay, reverb). Each LFO's rate can lock to a musical subdivision of the tempo. • Per-voice timing envelopes — fade in over minutes, fade out later, repeat N times or forever. Rotate harmonically across 20 minutes without touching a slider. • Six tuning systems: 12-TET, just intonation, Pythagorean, Lou Harrison Free JI, Wendy Carlos α/β/γ, Harry Partch 43-tone DESIGNED FOR THE DRONE TRADITION • 110+ presets across Drone Artists, Developer Patches, Solfeggio, Natural Resonance, Cymatics, Mystic & Composers, and Binaural categories — plus an INIT preset pinned at the top • 48 Drone Artists tributes — Oliveros, Riley, Radigue, Stars of the Lid, Sunn O))), Basinski, Niblock, Palestine, Budd, Coltrane, and more — capturing each artist's waveforms, FX, and tuning, not just their pitches • 21 Developer Patches showcasing granular sampling, BPM-locked grain density, FX-Mix LFO swells, and the JG hybrid pad/groove series • Modal chord category — the 7 diatonic modes plus Harmonic and Melodic Minor — with quantize-to-scale so pitch-modulated voices arpeggiate across all 7 mode degrees • Auto-morph between any two presets over 30 s to 60 min • 25 scripted meditation journeys (Deep Listening, Heavy Resonance, Minimalist Arc, and 22 more) • Tune to Room — global LISTEN snaps the chord root to a pitch from the mic; per-strip ear icon snaps just one voice LIVE CYMATICS THAT BREATHE WITH THE AUDIO • Physically-calibrated Chladni patterns fit from real plate- vibration footage. The renderer crossfades between two adjacent eigenmodes bracketing each voice's live frequency — vibrato breathes between physical modes, not styled animation. • Pinch to zoom; tap to enter fullscreen Performance mode with a drifting sand-particle simulation along the nodal lines • Cymatic snapshot gallery + spectrum-analyzer alternative GRANULAR + TEMPO • Granular waveform: pink noise chopped into Hann-windowed grains with size, density, jitter, stereo spread, per-voice overlap • Granular sampling: same scheduler on any loaded sample — freeze a bansuri forever, smear a chord into a tape-decay cloud • BPM-quantized density (½ → 1/32T) locks grain spacing to the global tempo. Per-LFO rate sync extends musical subdivisions to LFO speed. Metronome click toggle for an audible reference. RECORD, SHARE, AND COMPOSE • Mastered session recording: 24-bit WAV + AAC M4A sidecar with loudness normalization, automatic fades, embedded metadata • Per-voice mic record captures into a voice's sample slot — normalized, granular-ready, with the current frequency as the sample's reference pitch • 50+ bundled samples: bansuri, organ, piano, storm, tide, forest, urban, cosmic • Cross-device preset sharing via .dronepreset files — AirDrop a patch between web, iPhone, and iPad, samples embedded inline. iCloud auto-syncs samples-free presets across devices.

AumChord is an Ambient Chord Synthesizer with seven pads, a joystick and instant sound. Pick a key and every pad plays a chord that fits, so you can make music without knowing any theory. SEVEN PADS, ONE JOYSTICK Seven chord pads, one for each step of the scale, in all 12 keys, major or minor. Hold a pad and push the joystick to change the chord: add a 7th or a 9th, suspend it, strip it down to a power chord, open up the voicing or jump an octave. Switch to mono for single-note lines, or let the arpeggiator play the notes of a held chord in a shuffled order. AumChord is an instrument. Anyone can play it in a minute, and the more you learn its moves, the more it gives back. SOUND ENGINE 17 built-in sounds from AumChord's own synth engine, each with its own filter, reverb and delay. Switch between them at any time. New sounds arrive with updates, so there is always something new to play with. RECORD, LAYER, KEEP Pick a length of 1, 2, 4 or 8 bars, turn on the metronome and record. Stack up to three loop layers, each with its own volume adjustment. Save loops to your library or share them as WAV files to use in your own projects. PLAY EVERYTHING ELSE AumChord is also a controller. Every chord you play goes out as a MIDI signal, so the same seven pads and joystick can play any synth you own: another app on your iPhone, or a full studio setup on your computer over USB. One finger, full chords, in your own sounds. BUY ONCE, KEEPS GROWING No subscription, no in-app purchases, no account. Improvements and new sounds arrive as free updates.
