uJOVE, micro version of JUVE multimode filter

Post by Shayshez » Mon Nov 19, 2018 7:35 pm

I'm happy to introduce my recent project, uJOVE, micro version (8HP) of System80 JOVE filter.
JOVE is one of my favourites filters, multimode with LP24, LP12, BP and HP that inspired from Roland Jupiter 6 filter.



uJove is the same circuit and sounds exactly as the original Jove.
I added 2 extra mods:
- Level 2 act as positive feedback control when no jack plugged to input 2
- Input 2 can be clipped and not only attenuate.

the module will be available only as DIY project at Pusherman store (in month or so).

This is great! The 14hp version is too bloated for any single channel filter I'd put in the rack.

The module looks and sounds super nice! Just one question, out of interest: From my very basic understanding of filters, resonance is just an internal feedback loop. Does the added feedback mod mean that there are 2 different types of resonance for the uJove? If so, can you clarify the difference between them?

Thanks and well done again!
Tom

Hi Tom, great question!
Resonance is inverted feedback (negative feedback), I added to uJove positive feedback with extra 6db of gain.
as you can hear from my video it's sounds totally different from the resonance and can drive the filter to new timbers.
actually you can patch positive feedback with any filter, just split the output (with stackable cable or mult) and use mixer in front of your filter to mix the feedback loop with the signal that goes in to the filter.

just curious, is this done with the consent of the original builder? i know Mutable publish all their code as Open Source after a run or two, did System 80 go that route too?

It’s open sorce with different license then Mutable.
CC BY-NC-SA license allowes to remix the project but not allowing commercial use.
I talked with the original developer (system 80) and got his confirmation to sell pcb’s and panels (we not allowed to sell assembled modules).
