GrainHeads granular synthesis app for iPhone: Free to Download

GrainHeads granular synthesis app for iPhone is an iOS app that brings granular synthesis to the iPhone and is available as a standalone app or as an AUv3 plugin. The app is free to download on the App Store; an in‑app upgrade of $6.99 unlocks recording with the device microphone and the ability to load external samples.

GrainHeads provides eight independent granular playheads, each with dedicated controls including parameter adjustment, volume, and a Moog-style ladder filter. The Moog-style ladder filter per playhead offers selectable 12 dB or 24 dB per octave slopes, self‑oscillation, and overdrive.

The app includes eight LFOs for modulation of virtually every parameter and a multi‑touch 2D performance pad for live interaction. A 16‑step polyrhythmic sequencer offers locking to pitch, grain size, position, and additional parameters.

Effects comprise noise, a BPM‑syncable stereo delay, and reverb with filtering, and audio routings can be changed by dragging and dropping on the performance pad. A Dice Randomizer lets users randomize every parameter with a single tap, and further information is available on the GrainHeads website.

GrainHeads offers eight independent granular playheads, each with its own set of controllable parameters and a dedicated volume control. Each playhead includes a Moog-style ladder filter with selectable 12 dB or 24 dB per octave slopes, self-oscillation, and overdrive. The app provides eight LFOs that can be assigned to modulate virtually every parameter across the playheads. A Dice Randomizer function is available to randomize parameters across the instrument with a single tap.

The interface includes a multi-touch 2D performance pad for real-time interaction and drag-and-drop audio routing between elements. A 16-step polyrhythmic sequencer is included, with step locking options for pitch, grain size, position, and additional parameters. Effects provided include noise generation, a stereo delay that can be BPM-synced, and a reverb with filtering. Audio can be used standalone or via the AUv3 plugin format, and recording and external sample loading are available through an in‑app upgrade.

GrainHeads includes built-in effects that comprise noise generation, a stereo delay that can be BPM-synced, and a reverb with filtering. The stereo delay is described as BPM-syncable, allowing delay timing to align with the app’s tempo settings. The reverb effect features filtering as part of its parameters. These effects are listed among the app’s audio processing features.

GrainHeads includes a Dice Randomizer that randomizes every parameter with a single tap. The source material presents this functionality with the quoted phrasing that the Dice Randomizer can randomize everything in one tap. The Dice Randomizer is listed alongside the app’s other performance and sound‑design tools in the provided description of features. The feature is presented as a one‑tap action for broad parameter randomization within the app’s interface.

GrainHeads is free to download with an in‑app upgrade priced at $6.99 that enables recording with the device microphone and loading external samples.
