## What it is
The logue SDK is KORG's official software development kit for building custom oscillators, synths, and effects ('units') for prologue, minilogue xd, NTS-1/NTS-3, drumlogue, and microKORG2 instruments. It includes APIs, build tools, and a web-based simulator for developing and debugging DSP code in the browser.

## Use cases
- build custom oscillators for the KORG prologue
- write custom effects for minilogue xd
- develop reverb and delay units for NTS-1
- create drum effects for drumlogue
- test DSP code in a browser simulator
- port audio plugins to KORG synthesizers

## When to choose
- you own a compatible KORG logue-family instrument and want custom oscillators or effects
- you want to develop embedded DSP code with an official toolchain and web simulator

## When to avoid
- you need a general-purpose audio plugin framework like VST or AU
- your hardware is not a KORG logue-family product

## Facets
- artifact type: library
- maturity: active
- function: sdk, audio-processing, embedded, developer-tools
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, cpp, wasm, cross-platform
- tags: dsp, synthesizer, korg, firmware, oscillators, effects, music-production, audio
