Quanta is a six-voice granular synthesizer for iOS11+ in both standalone (with Inter-App Audio) and AudioUnit V3 formats. Quanta for iPad is fully compatible with the full version of Quanta for macOS and Windows; visit for a PDF manual, audio samples, and video demonstrations. Quanta will work on any iPad that can run iOS 11, but keep in mind that it is a feature-heavy desktop quality synthesizer, and would prefer a 2017/2018 iPad, or an iPad Pro. If you're experiencing CPU issues on lower-end machines with the standalone, try changing the main display to FEG or FLFO, which don't require redrawing and which will be significantly lower in CPU usage. >> Multi-Format Sample Loader Quanta can load AIFF, WAV, Broadcast WAV, FLAC, MP3, and Ogg in any sample rate, bit depth, and channel configuration. >> Grain Engine Up to 100 simultaneous grains per voice, of up to 1 second long, with control over grain rate, pitch, direction, shape, length, panning, source position, and level. >> Sidecar Oscillator Continuously variable wave shape, with pulse width modulation, and independent control over pitch (separate from grain engine.) Can be injected directly into grain engine. >> Noise Source Noise source features a "color" control that affects tonal characteristics of the noise. Can be injected directly into grain engine. >> Dual Multi-Mode Filters Filters can be used in serial or parallel modes, and include lowpass, highpass, bandpass, and notch in 2-pole and 4-pole configurations. >> Flexible Envelope Generator (FEG) x 4 The four FEGs are arbitrary function generators, with up to 99 steps, curve and step level control, arbitrary loop points, and host tempo sync. >> Flexible Low-Frequency Oscillator (FLFO) x 2 The pair of FLFOs utilize four controls (phase, shape, skew, and warp) to access a virtually limitless palette of waveforms, and feature host tempo sync and retrigger. >> Sample And Hold The S&H mod source can sample noise (random) or any of the other mod sources, at either a user-defined rate or a musical division. >> Modulation Matrix Every mod and MIDI source can be easily and simply assigned to any destination using the quick-access bi-polar modulation matrix. Touch a destination on the UI and the matrix automatically scrolls to the correct row. >> Tuning Tables And Global Tuning Offset Re-tune Quanta to new intonations and temperaments using the open-source and easy-to-use TUN file format. A global tuning offset (default to A=440) allows you to easily retune the entire synth to match a different A frequency without using a tuning table. >> MPE (MIDI Polyphonic Expression) Quanta understands both "legacy" MIDI and MPE. Use your Linnstrument, Roli controller, Haken Continuum, or Madrona Labs Soundplane (among others) to directly access per-note pressure, pitch bend, and modulation. >> Per-Instance Settings Quanta utilizes a per-instance customization method: set MPE mode, aftertouch smoothing, pitch bend range override, tuning table, and global tuning offset for each instance in your AUv3 host. >> Factory Presets Quanta comes with a substantial collection of factory content, including Designer Presets from Marcus Fisher, Joseph Fraioli, Chris Carter, and Richard Devine. >> Cross-Platform Preset Format Quanta utilizes an XML-based preset manager, and stores the sample within the preset for easy asset management. Work between multiple systems without troubles, make a preset on your desktop machine and paste it to the iOS version with Handoff or vice-versa, easily share your creations with your friends, or make a preset bundle to sell, no asset management required. >> Fully Resizable Retina GUI Quanta's vector-based GUI is resolution-agnostic, and displays the same on every system and resolution. Easily resize the UI (per instance) to match your visual needs, from postage stamp to poster-sized.

I bought it last night and like it a lot. Haven’t watched any of the demo videos at all, but was able to get going quickly making my own sounds. Import of my samples was easy and straight forward. Figured out half the app on my own without manual, tutorial or demo in less than an hour. Downloaded the factory preset samples that are all magnificent. Seeing how they were made, ie. their settings... got me another 25% more knowledgeable of the app within another half hour or so. Getting to the last 25% of depth with take a bit more time of exploring. Overall, excellent UI design and very intuitive. I wish there were a way to see what your adjustments are doing to the visual pane the has the grain/wave thing while you’re making adjustments instead of having to switch back and forth. Well designed and sophisticated granular sound design app that’s easy to figure out without too much effort. It reminds me of the high level of hardcore sound design capabilities inherent in Igor’s superb Soundscaper synth, but easier to grasp the UI. Would buy this one again in a heartbeat.

When I first bought the synthesizer I thought to myself this looks very odd as I played with the sounds it allowed me to control so much I also like the idea of how they were sampling the sound in and allowing you to touch all over it. I made a song with this for the first time just the other day I’ve owned the app for about three months. I have been missing out on one of the greatest instruments on my iPad I am in love with that very oddly in love with it.

I’m really enjoying this app so far. Really unique and fun to play. However, I've run into a little issue... I often run multiple iOS music apps simultaneously — some of which send MIDI to my computer over a network connection. In these situations, Quanta is automatically picking up the MIDI notes being transmitted on that network connection (which I don't want). In Quanta, I went into Settings > I/O Settings, and attempted to turn off all "active MIDI inputs." However, it will not allow me to uncheck any of the boxes to disable them. They just immediately re-check themsleves. Any idea why this might be happening? Any help would be much appreciated. Thank you!

A straight forward granular synth without an experimental interface and lots of modulation options. I’ve just spent a few minutes with this but can already tell it’s going to get a lot of use. ** iPad mini 2 note ** so far it is a little slow on my iPad mini 2 for instance when switching from the sample load / preset screen to the synth interface but I’m sure Audio Damage will address this as every app I have from them is solid.

The app provides a lot of control and options for getting the most out of your samples. Being able to import samples from the Files app within Quanta is great. The ability to create complex envelopes to shape your sounds is a unique feature. Comes with lots of well designed presets. You can set the number of voices to minimize the DSP needed to create your music. Automating the exposed AU parameters adds more flavor to the mix.
