* How to import the custom oscillators and effects

Custom oscillators and effects are distributed in the form of a “user unit” file. To add an oscillator or effect, drag and drop the user unit file onto the corresponding list in the NTS-1 Sound Librarian, and press the SEND ALL button to upload it to your NTS-1. Please refer to the Operation Manual included in the NTS-1 Sound Librarian for further details

Factory Default User Oscillator: Waves

The NTS-1is preloaded with one user oscillator: Waves. This oscillator is stored in one of the 16 slots available for user oscillators. It consists of two main wavetable oscillators and an additional sub wave that can be optionally used as a ring modulation source. The bit depth of the mixed output can be reduced for a lo-fi effect. The source code for Waves is available as a template along with the SDK source code on GitHub, so new and unique oscillators can be created.
