The outstanding hybrid synth for iPad, iPhone and iPod touch! • Palm Sounds App of the Week (Christmas 2011) • iDesignSound App of the Week (January 2012) • “I ----ing love this thing!” — Discchord video review • Grain Science is a beautiful synthesiser for iOS. Designed for musicians, soundscape artists and SFX engineers who want to go beyond our Sylo Synthesiser, Grain Science is built on similar principles of granular synthesis, but is vastly more powerful. Unlike many “experimental” granular apps, Grain Science mixes it up with traditional synthesis techniques to bring you an exciting hybrid synthesiser. Use the built-in waveforms, or record or import your own — then use the sophisticated grain engine to create something completely new from them! Grain Science is easy to get to grips with, but offers lots of depth to explore: instead of offering one or two LFOs, almost any parameter in the system can be programmed to vary over time in complex ways. Using careful optimisation techniques we provide two grain units per voice, which you can combine for morphing or complex modulated sounds, then send through a configurable FX chain. Pick any 4 from the collection of FX units (including various types of distortion, high- and low-pass filters, phaser, flanger, chorus, resonance and echo), and connect them up in any order. Other audio tweaks include soft loop, reverb, glide and supercharger controls, and the ability to affect granular synthesis in realtime (live grainbending). Also featured are an arpeggiator with both chord and step-sequence modes; Core MIDI support, including Virtual MIDI, background audio, and “tap & twist” learning for setting up controls; and a customisable performance screen with a collection of XY Pads and wheels. Rounding it off, Grain Science plays nicely with others: Dropbox, Twitter and email integration are all included, for sharing or exporting your waveforms, recordings of your performances, and instrument (patch) designs. And now featuring Audiobus support to stream your performance live to other compatible apps!

Certainly not ABSOLUTELY perfect, but 95% of it is. The most notable thing is the reverb disengages upon a notification or phonecall, but to get it back engaged, one simply moves the “gain” or “wet” reverb parameters a wee-slight bit, then the reverb is fully present most importantly, the way you had it set originally. The one issue I wish wooji juice to buckle down is the “arppegiator” tempo really isn’t fully accurate, and it seems only explained by comparing how powerful the synth and signal path can be that maybe there isn’t enough left in the App to ensure real time BPMs. I love the idea of the parametric sequencer but it’s under the same clock issue so i don’t use it because it can’t articulate smooth parametric changes if the clock isn’t on time. One of the many home runs is the “lock” for the keys, and the “chord” arppegiation which can be used to compose MASSIVE drones and soundscape, morphing guitar sweeps(if you record into the mic) and sequences that take about a month to cycle through. Combining that with the most notable tool, the parameter LFOs found on about 90% of controls(including flange and chorus rate for doppleresque effect!) you can modulate both octave and pitch with their own respective wave shapes and make sequences last over a year, see you next thanksgiving! The xy section is a truly advanced area and should come way after one grasps the apps main functions, along with the ribbon controler. One more occasional glitch occurring during looping grains can be heard to shift harmonics for no reason, so just switch out of the synth mode during looping and switch right back, glitch erased. so these two glitches can be worked around, i would ask apple to implement a sixth star if you make the clock keep accurate BPMs, but pretty sure your over it. I’ll still enjoy the inter dimensional sounds coming out of this phone, regardless. thank you. ### 1/5 — Won't Open Anymore *2018-04-05, version 1.4* App will not open. Crashed instantly. ### 4/5 — Really wish it had AUv3 support *2017-08-02* The engine sounds really terrific, the UI is intuitive, and the app supports multichannel midi input. It doesn't yet work with Audiobus 3's MIDI input feature, though, or support being loaded as an AUv3 ### 5/5 — Classic must-have granular synth *2017-05-20* Some fantastic sounds. Highly recommended. Thanks for the update, Wooji Juice! ### 5/5 — A winner *2016-11-15, version 1.6.3* I think I may love this synth even more than the mighty Mitosynth. ### 5/5 — Updated *2016-03-26, version 1.6.3* One of my favorite synths. ### 5/5 — I can't believe how good *2015-10-21, version 1.6.2* I can't believe how good this synth is. I have a lot of vst plugins I wish this were one them!! ### 5/5 — Fantastic! *2015-09-18, version 1.6.2* The amount of control over every nuance of the sound, evolving through time is impressive. It does have excellent presets if you are a beginner to synthcraft, but the power of its engine, parameters, and effects will satisfy synth masters too. ### 5/5 — Outstanding iOS synth *2015-08-13* Like other synths, Grain Science has a learning curve, but reading the manual really helped. The app has preset granular synth sounds, but Grain Science really comes into its own when you use the synth to convert recorded instrumental and other sounds into granules, recombine the granules in various ways, and then use the synth's filters and other tools to create novel sounds. This is an outstanding synth. ### 5/5 — Buy it! NOW! Chuck Noris will slapYou in the face!!! *2015-05-15, version 1.6.1* Great app! ## Frequently asked questions about Grain Science ### What is Grain Science?
