Drone Meditations vs Patchsynth

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. One-time purchase. No subscription, no accounts, no tracking. Free web version: dronemeditations.com

Patchsynth is a Eurorack-style modular synthesizer for iPhone and iPad — and a place to actually learn how modular synthesis works, one patch cable at a time. Instead of a fixed synth engine with knobs, you build your own instrument by dragging cables between modules: oscillators into filters, envelopes into amplifiers, LFOs wobbling anything you point them at. If you've ever wanted to understand what a Eurorack rig actually does, this is the fastest way in. LEARN BY PATCHING, NOT BY READING 28 hands-on Lessons cover every module, from your first oscillator to full generative patches — some just explain, others build a real patch step-by-step in front of you as you tap "Next." No prior synthesis knowledge required. TRAIN YOUR EAR 15 Challenges hide a patch and play it for you — your job is to rebuild it by ear, with hints if you get stuck. A genuinely fun way to internalize how filters, envelopes, and modulation actually sound. 21 REAL MODULES Oscillator · Filter · VCA · ADSR Envelope · LFO · Noise · Delay · Reverb · Mixer · Sequencer · Arpeggiator · Clock · Attenuverter · Quantizer · Slew Limiter · Sample & Hold · Logic · Ring Modulator · Sampler · Keyboard · Output (with a live oscilloscope) Record your own sounds with the Sampler, or use the built-in factory drum kit. Quantize any CV to a musical scale. Chain multiple clocks for polyrhythms. It's a real modular rig, just without the cables costing $30 each. 70+ FACTORY PATCHES From simple bass and pad sounds to sprawling, 20+ module "flagship" patches — browse them, load them, take them apart to see how they're wired, then make them your own. PLAY IT WITH REAL GEAR Full MIDI support over Bluetooth or USB — plug in any MIDI keyboard or controller and play your patch's Keyboard module directly, no setup beyond pairing. BUILT FOR TOUCH, NOT PORTED FROM DESKTOP Every interaction — dragging cables, turning knobs, panning and zooming a big patch — is designed for a phone screen from the ground up. A dedicated Patch Bay view even gives you a spreadsheet-style matrix of every connection when patches get complex. Undo and redo everything. Save as many patches as you like. No ads, no in-app purchases, no internet connection required — just synthesis.
