Complete Audio Development Suite

From raw samples to signed installer. Our Gorilla Engine SDK handles the entire lifecycle of your professional audio plugin.

Gorilla Editor

Define your sound core. Stack samples, route audio, add envelopes and LFOs, and export to .blob files.

Gorilla Tester

Instant DAW preview. Load .blob files directly in a VST/AU wrapper to test your product before compiling.

Gorilla Compiler

Bundles your .blob, UI assets, and logic (JS) into signed installers for VST, AU, AAX or Standalone.

UI Development Layer

Build pixel-perfect interfaces using our layout system and standard JavaScript for interaction logic.

Gorilla Script

Scripting language for the core audio engine. High degree of familiarity with KSP. Binds controls to internal parameters effortlessly.

NKS & MPE Ready

Fully compatible with Native Instruments NKS standard and supports MPE (MIDI Polyphonic Expression).

Separation of Concerns

Sound, Layout, and Logic.
Perfectly Organized.

Gorilla Engine splits development into logical parts. Use Gorilla Script for DSP binding and JavaScript for complex UI behavior. This allows instrument designers and UI developers to work in parallel.
