NTS-1 digital kit NTS-1 digital kit



logue SDK

NTS-1, prologue, minilogue xd and minilogue xd module share an open development API (Application Programming Interface) that allows users to extend the possibilities of the hardware via an SDK (Software Development Kit) and dedicated development tools. Via this SDK custom digital oscillators can be created for the MULTI ENGINE, and custom modulation effects can be added to the existing modulation effects. Users can then load these new custom oscillators and modulation effects into their NTS-1 via the prologue Librarian application (Mac and Win).


* The SDK code, tools  and  documentation are now available on  GitHub
* Reference:
* To manage the User Oscillators and Effects in your NTS-1 you will need the NTS-1 Librarian application.
* The Librarian, as well as Custom Content for the NTS-1, when available, will be featured here:
Click here to go to the NTS-1 Librarian&Custom Content page

User Oscillators

NTS-1’s MULTI ENGINE section has 16 user slots to accommodate custom oscillators.
Use the TYPE know while pressing the OSC button to select the custom parameter you’d like to edit and use the B knob to change the parameter’s value

User effects

NTS-1’s effects section also has 16 user slots to accommodate custom modulation effects, 8 user slots for Reverb effects and 8 slots for Delay effects.

Once loaded via the NTS-1 Librarian application these custom effects will appear alongside the existing modulation effects. The A and B knobs can be used to control parameters of these custom modulation effects.

Obtaining custom oscillators/effects

Custom oscillators/effects created by, or in collaboration with, KORG are featured on the Librarian&Custom Content page. 3rd party developers are free to distribute their custom oscillators/effects through alternative channels such as community websites, forums, GitHub etc and in some cases featured here.

Loading custom oscillators/effects

In addition to the usual program management functionalities, the librarian application can be used to load and remove custom oscillators and effects via USB MIDI. The Librarian is a user-friendly software that allows you to manage the the custom oscillators and effects on the NTS-1.

(The NTS-1 Librarian will be available soon)

Will there be a patch editor to customize internal parameters of the on-board effects?
There are no editors planned for customization of on-board effects.

Will the librarian be implemented as a VST/AU plug-in to facilitate automation of minilogue xd and storage of patches with DAW projects via Snapshots?
No, not for this version of the Librarian.

The logue SDK provides a set of code libraries and tools to allow the creation of custom oscillators and effects.

For more detailed information, please subscribe to the logue SDK mailing list you can find below.


Can I use the SDK Custom Content from prologue and minilogue xd on NTS-1? (and vice versa)
Check with the content creator to see if a NTS-1 specific version is available. If not, the other versions can be used directly.

Do I need programming experience to create my own content?
Yes. Please note that as opposed to the Librarian application, the Developer kit is a standard development kit meant for programmers, and not a neophyte-friendly high-level editor. We expect that oscillators and effects will be programmed and distributed by pro and hobbyist software developers. It will be an open development kit aimed at experienced users so we will not be offering technical support beyond the provided documentation.

What programming language can I use?
Custom oscillators and effects can be written in C, with support for a subset of C++. What limitations are imposed in terms of available RAM? (it would have to be reasonably finite). For oscillators, both code and variables must fit in 32KB of RAM. Custom effects will have additional RAM for delay lines, up to 2MB.

For the multi-engine, will the LFO be able to modulate its parameters?
The LFO can modulate the shape parameter of the multi-engine. Custom oscillators will be able to take advantage of this.

How many editable internal parameters can a custom oscillator have?
Parameters for custom oscillators are limited to 6. This is a deliberate limitation to keep custom oscillators straightforward and simple.
