Happy 9/09 Day! Introducing the ER-99 web drum synth

Celebrate electronic music history on 9/09 day with ER-99, a web-based instrument 🎛️ based on a famous Japanese drum machine from the 1980s. It was built to celebrate 9/09 day 2022 🎉!

All of the drums are synthesized using the WebAudio API. The hi-hats, crash, and ride cymbals are produced from sampled audio.

The complete source code is available on Github:

Cool little machine!! after I create a basic sequence, it doesn't "clear" so I can create a new sequence!! Parts of previous sequence continue to play. Quite frustrating!!
How can I CLEAR ALL SOUNDS SO I CAN CREATE NEW SEQUENCE???!!!
