Note: For the full experience with parameter controls, song generation, and real-time playback, please download and run locally.
The application has been refactored from a monolithic 2600+ line file into a clean modular structure using ES6 modules.
./r- Launch the application (modern modular architecture)./r-original- Launch the application (same modular version, nostalgic launcher)
The application now generates industrial/electronic themed lyrics that sync with your music playback. Each song gets unique, thematically appropriate lyrics inspired by artists like Nine Inch Nails, Ministry, and KMFDM.
JsIndustrialProducer is a web-based application that generates industrial/techno MIDI songs with customizable parameters. This tool allows musicians and producers to quickly create industrial-style MIDI compositions that can be imported into digital audio workstations (DAWs) for further production. While designed for industrial music, the application can produce surprisingly calming ambient soundscapes at slower tempos (60-80 BPM), offering versatility beyond its industrial roots.

- Range: 60-140 BPM
- Default: 70 BPM
- Description: Controls the speed of the song. Lower values (60-80 BPM) create slower, more atmospheric and surprisingly calming ambient tracks, while higher values create more energetic industrial compositions. Despite the industrial theme, slower tempos can produce meditative soundscapes.
- Range: 1-10
- Default: 7
- Description: Affects the velocity of MIDI notes and the volume/filtering of the preview. Higher intensity creates more aggressive, louder sounds.
- Range: 0-100
- Default: 60
- Description: Applies waveshaping distortion to the bass sounds during preview. Higher values create more industrial, gritty textures.
The easiest way to run INDUSTRIELL KLANGMASCHINE:

The application generates MIDI data in real-time using bitwise operations to create proper MIDI byte sequences. The Web Audio API implementation uses oscillators, filters, and gain nodes to approximate the sound of classic industrial synthesizers. The distortion algorithm uses a waveshaping technique that emulates analog distortion circuits.
