Love this. May I know the tech stack involved in this?

Thank you.

For your reference

Language: TypeScript UI: React State management: MobX Deploy/Hosting: Vercel

And it uses some browser features. WebAudio is used for audio output. WebGL is used in react-pixi to render many notes faster.

it "works" in firefox, but the playback is laggy and weirdly timed. very cool tho!

Thank you! Timer related behavior may be a problem. I will investigate more.

The latency is horrendous, I use a real-time kernel to make music @3ms< you're never going to get that with a fully streaming application however, you could possibly send bigger chunks of data which interact on the client-side. It's still problematic, but bravo! Valiant effort.

It nice! Does it support external peripherals?

Thank you. I would like to support MIDI input / output in the future. Can you tell me about the equipment you want to use?

I’d love to be able to use Novation LaunchKey MIDI controllers.

The name might be problematic, because of https://www.signal.org/

I try to use Firefox on principle, but I find so many sites are slightly or significantly broken in it

It could be because Firefox reduced time precision to fend off fingerprinting and timing attacks. To turn it on, you’d need to set the Cross-Origin-Opener-Policy to “same-origin” and the Cross-Origin-Embedder-Policy to “require-corp”.

Maybe, but I don't think so, it serves a completely different purpose.

This entire application is client-side.
