Jeskola Buzz has a pretty interesting back story:

>The development of the core program, buzz.exe, was halted on October 5, 2000, when the developer lost the source code to the program. It was announced in June 2008 that development would begin again, eventually regaining much of the functionality.

I think “simulate” would’ve been a more accurate word than “build”.

It warms my heart to see the 303 getting a renaissance

This is cool, but I would personally find an og iMac and install rebirth.

It’s a nice demonstration of this software but it really sounds very little like a 303

Sounds like a real bad day.

The fun thing was the Roland Sync. You could sync up all the TB-303, TB-909 and all the others with a 5-pole DIN cable. The sync was badly implemented. It lagged, it had latency.

However!

As soon as you cabled all together their imperfections added up and they started to groove like nothing that has been heard before.

Try tweaking the accent multiplier to .1 from .5 - you can get there but it requires a lot of value tweaking. There's no singular TB-303 sound, but the components are there.
