This post on el reg appealed to me for some reason today ,,,
Re: I will laugh so much...
ReBirth is sounded pretty dated now, though. There's far more convincing virtual analog synths around; although ReBirth ran nicely on a 60MHz processor and was amazing for its day. Which was 16 years ago. I would expect some future TB-303 clone to be running a SPICE simulation of the actual circuitboard*
And that user interface? What were they thinking? Yes to emulating the TB-303 sound, no to emulating the TB-303 pattern editor
* OK, admission time, I tried this. You have to run the simulation at 1MHz in SPICE to capture the oscillator triggers, and there are enough non-linear components that you have to use something like conjugate gradient to solve it, and that puts it out of the 1MHz sample rate even on a 3GHz machine. You could possibly run the filters at a lower sample rate and analytically create the input waveforms though - the SPICE waveforms, even with non-perfect components, are pretty much mathematically perfect. But I digress.
