What is Mini Synth?

Mini Synth is a simple Tone.js synthesizer built with SvelteKit. It runs in all major browsers and was designed to provide Ugandan refugees with a tool to create music digitally.

Launch the production website or learn more about this project in my portfolio.

Technical Overview

Mini Synth is built using SvelteKit, mostly written in TypeScript, and styled with Dart Sass. The production site is deployed using Vercel. All audio capabilities are built using Tone.js and all songs are stored using IndexedDB with Dexie.js.

Getting Started

To run the code locally, you must have Node.js installed. Then, run the following in a terminal in this project's root directory:

# this will install all dependencies
npm i

# this will start a development server and open the app in a new browser tab
npm run dev -- --open
