Introduction

A simple musical synthesizer for running short snippets of code which produces momentary amplitude. It inlines the sound as an uncompressed wave file in a data: embed for maximal retro-compatibility of playback. The input is not sanitized and the runtime is not sandboxed, so only paste in expressions that you trust!

You can install a web browser that supports at least JavaScript 1.0 (1995) to run this application or you may consider implementing a GemiWeb0 browser with JavaScript0 yourself according to the following specification:
