Quanta is a six-voice granular synthesizer for iOS11+ in both standalone (with Inter-App Audio) and AudioUnit V3 formats.

New version 1.1.2
Old version 1.1
Release Notes New In Version 1.1.2 >>>> 1. The TUN loader now does its one job correctly. TUN files will correctly be loaded and applied, for all your alternative tuning needs. 2. All the settings in the SETTINGS panel can now be saved as the global startup state. 3. The factory preset payload now includes the Hainbach presets. The only way you can get this is by deleting the app entirely, re-installing it, and re-downloading the Factory file, unfortunately. If you have user presets, these will be deleted as well, so plan accordingly. Existing sessions, however, will not be affected. This is an optional thing, but if you like a tidy workspace, this will do it. 4. Much refactoring and optimization under the hood, along with many small bug fixes. A whole lot of otherwise dumb pointers have been en-smartened.
