React Synth 🎹

This is a fun little experiment showing that React API can be used outside of browser environment to render... music instead of HTML.

Should you use it? I don't know, you are an adult.

Quick start

Init new repository and install react-synth and its dependencies:

npm init
npm i @react-synth/synth react
npm i -D @types/react

Then create new .tsx file. React-synth requires created file to have default export with ReactNode. For example, you can paste below code:

// song.tsx
import React from "react";
import {
  Chord,
  Loop,
  Note,
  Sample,
  Sequence,
  Synth,
  Track,
} from "@react-synth/synth";

export default function MySong() {
  return (
    <Track bpm={120}>
      {/* Simple kick drum pattern */}
      <Loop id="kick" interval={1}>
        <Sample name="bd_haus" amp={2} />
      </Loop>

      {/* Melody arpeggio with prophet synth */}
      <Loop id="melody" interval={2}>
        <Synth type="prophet">
          <Sequence interval={0.25}>
            <Note note="C4" />
            <Note note="E4" />
            <Note note="G4" />
            <Note note="C5" />
          </Sequence>
        </Synth>
      </Loop>

      {/* Chord progression */}
      <Loop id="pads" interval={4}>
        <Synth type="hollow">
          <Chord notes="Am7" release={4} amp={0.5} />
        </Synth>
      </Loop>
    </Track>
  );
}

Then run it with:

npx react-synth song.tsx

Now any change made to the code will cause hot reload without disruption.
