a naive TB-303 sound synthesizer library, which another story [1] reminded me of.

Anyone have some audio samples generated with this? As a 303 junkie, I would love to hear how closely it resembles a real 303.

Sounds like this: https://www.a1k0n.net/code/webkitsynth/

Basically, not at all like a 303 except in spirit

Huh. I wrote this code back in 2000 or so. Didnt realize someone had ripped it.

It doesn't sound very much like a real tb303 whatsoever. I'm working on a JavaScript one based on an x0xb0x I built, but it has a long way to go.

Your Javascript 303 sounds really good! Are you planning to turn it into a full web app?

a1k0n5• 9 years ago

Some day, perhaps, but the code is MIT license and anyone is welcome to collaborate. (FWIW, @pcgregory turned my fasttracker 2 player into a full fledged tracker: https://wetracker.herokuapp.com/) I'm busy with other projects now; this is something I keep coming back to once in a while, and if I do it'll be to improve the fidelity before I make a pretty frontend...

It still needs accent emulation which is a bit of work, high pass output filter (it's bassier than a real 303 because there's some capacitors between the filter output and the amplifier I'm not emulating), the knob ranges / nonlinearities aren't quite right...

edit: And it also needs the square wave, which is super weird on the 303, as you're aware (yours has a sample for it I think)

a1k0n5• 9 years ago

oh right, you wrote the other 303 web app! I was kinda mad because you stole my thunder while I was working on this one. :)

Do you have any sample audio?

Having owned 2 tb303s and currently a modded x0x, it is as close as you will get reliably. The tb303 doesent even always sound like a tb303.

Here is the code for my Javascript 303 emulation: https://github.com/errozero/js-303-instrument/blob/master/ac...

It definitely needs some improvement.
