New: record your knob moves as MOTION, and play the DroneSynth plugin in Logic or GarageBand wirelessly from your iPhone or iPad.
As both a musician and a software engineer, I've always found drones incredibly useful for my musical creativity, supporting my practice with singing, flute, didgeridoo, and other instruments like synthesiser and guitar. That passion for music and technology led me to bring DroneSynth to iOS, built from the ground up for the Apple ecosystem. Including AU support for supported DAWs
DroneSynth turns your iPhone and iPad or Mac into a hands-on, analog-style drone synthesiser built for ambient textures, evolving pads, and hypnotic soundscapes — no menus to dig through, knobs you can hear. It now includes AU Support on all platforms.
Layer three independent oscillators — sine, triangle, square, saw, and pink noise — each with its own volume, octave, semitone, and fine-tune. Shape the blend with a full ADSR envelope and two independent LFOs modulating filter cutoff and pitch, each with sine, triangle, or random shapes and drift.
STEREO-CAPABLE MOOG LADDER FILTER
Sculpt your tone with a classic Moog Ladder filter, featuring live cutoff and resonance. Upgrade to true stereo filtering — two independently detuned filters panned hard left and right — for a wider, richer, more three-dimensional drone.
BUILT-IN EFFECTS
• Tempo-syncable delay with tap-tempo and ping-pong stereo bouncing
• Lush reverb across four distinct spaces — Room, Hall, Plate, and Cathedral — each with its own size, pre-delay, and decay character
PERFORMANCE-READY
• Drone/sustain mode for endless, hands-free evolving tones
• On-screen keyboard with adjustable octave and range
• Save and recall unlimited presets, so your favourite patches are always one tap away
• Adaptive layout — a focused portrait view and a full landscape control surface with a persistent sidebar, so every parameter stays reachable
Whether you're scoring a film, building a meditation soundscape, or want a synth that rewards knob-twisting over menu-diving, DroneSynth gives you real-time control over every stage of the signal path.
Stereo Filters is available as an optional one-time in-app purchase.
Ratings & Reviews
What's New in Version 1.3.1
Made for landscape
• Every drawer now fits on screen in landscape, without scrolling. Same controls, laid out more neatly.
• Open drawers hang down over the keyboard instead of squeezing it, and the keys they leave uncovered still play.
Hide the keyboard
• A new Keys button beside Drone hides the on-screen keyboard, giving its room to the knobs and drawers. Tap it again to bring the keyboard back.
Smoother to play
• Knobs grab your finger the moment you touch them, so they turn even inside a scrolling drawer.
• Naming and saving a preset no longer causes clicks or dropouts in a drone that's playing.
Better starting points
• The filter starts at 12 o'clock, and double-tapping it takes it back there.
• The ARP starts slower: 80 BPM, quarter notes, random order. Double-tap RATE to return to 80.
• MOTION opens on the controller, and new motions are timed in seconds by default.
