<a href="https://tonejs.github.io/docs/#MetalSynth">Tone.MetalSynth</a>
creates metallic, inharmonic sounds using 6
<a href="https://tonejs.github.io/docs/#FMOscillator">Tone.FMOscillators</a>
with a tuning based on the TR-808 Cymbal.
<a href="https://tonejs.github.io/docs/#MembraneSynth">Tone.MembraneSynth</a>
makes kick and tom-like sounds using a frequency envelope which is triggered on notes attack.
