Benjolino +
ok so, i was making some refinement and ended up with a more faithful interpretation of the original benjo, the data input of the rungler is now the XOR of VCO2 pulse and the last bit of the shift register and i added the nice FM bus of the original. Vco2 can modulate Vco1 and viceversa. It still lacks the “loop” function of the original but i’ll work on it!
Instead of an update i thing its better to have two versions, Benjolino and Benjolino + with added features but more cpu hungry.

You linked me into the hordijk synth workshop papers a couple of weeks ago. I in turn have passed that on to others who appreciate the resource. Again, here, your contribution is outstanding. Will download and let loose the bengiolino… many thanks

Benjolin!! I went nuts when I got one. Frees the soul.

I don’t need an emulation. But perhaps something more will come of your efforts, hyena!

“frees the soul” :slight_smile: perfectly put!
last night me and my loved one had a jam session, she on the theremin me on benjo (the actual module). we got totally lost in the beauty of those two solo instruments. i think we’ll study a minimal performance to bring live on stages :slight_smile: it was really lovely

@hyena

i am only getting a signal hard panned left, tried it as a mono channel and as stereo.
is this normal ?

#18

uh, i didn’t try it in a stereo chain, you are right, it comes out only from the left.
of course on a mono chain it doesn’t make sense to talk about left or right.
i suggest:
a)using it only on mono chains as it is not stereo (a true stereo unit would mean having every element doubled hence too much cpu).
b)if you need it in a stereo chain for some reason you might install kels library in which you’ll find PanMix , a unit to mix mono units in a stereo context.

i anyway strongly suggest you use it in a mono chain as it is pretty heavy on the cpu and adding other stereo units besides it can be a bit too much for the processor i’m afraid.

Very cool. I’ll check it out for sure. I literally only just bought an actual eurorack Benjolin this week so I look forward to delving into that first so then I can spot the differences/influences etc on your take of it.

Cheers.

welcome to the benjolin madhouse!
you’ll notice they sound very different both in terms of actual sound (analog vs digital and also the peculiarity of the all-harmonics distortion of the actual benjo filter when resonance is cranked up) and of generated “sequences”.
please let me know what you think of it once you try it :slight_smile:

#21

Updated the Bengiolino + version,
added a rectification to the filter rungling.
the old version had an odd behaviour where the rungler was modulating filter frequency down to (imaginary) negative frequency values.
now it behaves correctly and is more responsive than ever!
edited the original post with new unit, here’s the link:

Thank you very much for posting the synthesis workshop pages - such a great overview of everything an electronic musician has to know. And thank you also for giving me the chance to discover Rob Hordijk - super interesting and soulful person!
Looking forward to try your Benjolin-Klon, but i guess i need firmware 4. for this?

Yes,this heavily relies on the routing options of 0.4.xx involving feedback points that were priorly available only thru the use of global chains. Very glad you appreciated the links, so many infos on Hordijk synthesis workshop,all in a very ivulgative way

New experimental version ,Loop function implemented.
please give me feedback if you test it!
controls are the same of the Plus unit but with

  • Loop: locks the Rungler in a loop feeding the first sample and hold of the shift register the last bit generated, creating a feedback loop.

Benjolino +
at last a utility Bengiolino Plus update.

the bad news: i found out that my claim i was using a xored mix of vco1 data and last bit of the DAC was bs, there was just an Accents Logics unit wasting cpu cycles due to a bad implementation on my side. i tried to implement it correctly but the whole thing did not perform as i expected so the rungler data input is now back to vco1 out.

the good news: this reduced cpu% to an healthier 35% AND the loop function seems to work. another good news is that in a minute i’ll finally release (in a separate thread) the rungler part that you can use in a more modular fashion.

Is there an issue with the Logics unit that needs looked at?

#28

no @Joe, absolutely :slight_smile: it was only my fault :slight_smile: i was a bit lost in the mist of bengiolino when i implemented it seems ehehehhe

i edited the post because it sounded a bit like there was something bad in @joe’s logics unit, absolutely not :slight_smile: Logics works perfectly, i just did a wrong reasoning
