Benjolin inspired instrument



Following the conversations on analog circuits, I thought I would like to share a supercollider instrument inspired on Rob Hordijk’s Benjolin

You’ll need from sc3-plugins: PulseDPW, SVF and DFM1

code here:

A bit of background on the Benjolin:

Hey Alejandro,

thanks so much for sharing, this is super-interesting and sounds marvellous!
Will also need some time to look through -



Great that you like it Daniel. I am turning my head around about the PLL question.



This sounds amazing. I have an “authentic” analog Benjolin here and actually didn’t think it was possible to emulate digitally but this really does the trick but with an even larger potential. Great job!

By the way, you get a free gui if you type Ndef(\benjolis).gui (although not all params seem to scale correctly here)


I’d make one correction though and that is to add a DC filter to the output because this synth sometimes ends up in DC land which is a bit dangerous. So just add output =; at the end.


and a limiter!
output = output.tanh;

Here’s my version of it, the safety version, haha.


You get a gui also via ‘ed’ from NdefMixer(s), which is a bit hidden (I’m a rare Ndef user)


This is great. Really fun, thanks!
