## What it is
Open NSynth Super is an experimental physical hardware instrument that provides a tangible interface for Google's NSynth machine learning sound-generation algorithm. The repository contains all software, firmware, schematics, and build instructions needed to construct the instrument yourself.

## Use cases
- build a physical interface for the NSynth neural sound synthesis algorithm
- generate new sounds that interpolate between existing audio samples
- build a DIY hardware music instrument from open schematics
- explore machine learning audio generation in a music production rig
- customize or fork an open-source hardware synthesizer design

## When to choose
- you want to build your own NSynth Super instrument from scratch
- you need a hardware interface for exploring ML-generated sounds
- you want open schematics and firmware to remix into your own instrument

## When to avoid
- you need actively maintained software with up-to-date dependencies
- you want a plug-and-play commercial product rather than a DIY build
- you expect bug fixes or pull request reviews from maintainers

## Facets
- artifact type: application
- maturity: abandoned
- function: machine-learning, audio-processing, embedded, gui
- domain: machine-learning, hardware, audio
- platform: embedded, cpp, cross-platform
- tags: hardware-instrument, music-production, diy-electronics, sound-synthesis, magenta, raspberry-pi, audio, linux
