What's New


> Voice activity lights have been replaced with graph indicators. These show a sum of the level of mod going to the Output. (i.e. the graph is the total of everything routed to the OUTPUT channel in the mod matrix.) This gives a much better visual indicator of voice activity than the previous "is this thing on?" LED.

> FEGs now have animated activity indicators showing the progress of the FEG for every voice.
> FEGs now have a RESET button; this returns the FEG to its default "ADSR" state.

> FLFOs now have animated activity indicators for each active voice.

> Maximum voice count has been increased to 15 (only in desktop versions; iOS max voices remain at six). This should solve any lingering voice-rollover issues with MPE controllers.

> The salmon color of the interface has had its richness of salmon increased approximately 15%; we are confident this is the richest salmon color in the audio plugin industry.

> The voice stealing algorithm (which was the source of most if not all of the "clicks" that many users experienced) has been totally replaced, and Quanta is certified click-free.

> The cause of the CPU loading when the UI was closed on iOS was found and destroyed.

> Numerous improvements and fixes, and a complete rebuild against all current plugin SDKs.

App Description

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 audiodamage.com 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.
