Don't let me get your hopes up, I have no idea myself. It looks like your only option.
First guess would be to see if there's a resistor attached to either end of the LFO rate knob. Add a resistor in series, see what happens.
I'm pretty sure it won't be that easy.

Might be worth asking the maker. I had the same request for a Bender to Pittsburgh and they offered to do it for free.

I might contact him. I know they are busy right now, and it's not really a priority. It's also already lost its place in the rack. I've put it aside for a possible expansion for the moment.

Unsure if anyone else has noticed, but the first 25% (6 to 9 o'clock) of the LFO rate seems to not have any effect, rate is unvaried.
Can anyone confirm similar performance?

Ya I've noticed the curve on the frequency pot is kind of weird as well, Seems to slowly increase starting from slowest and turning up to around 1/2 and seems to speed up drastically last 1/4 turn to full speed. It's definitely not an even curve from slowest to fastest

Just read that might be intentional for the authenticity since the filter on the original Polivoks also shares similar characteristics regarding its resonance and cutoff!

Thanks for the pdf mt3. :guinness:

Also having the same problem as Avjr. Mine just arrived today but the pcb literally seems to be sawed off at the bottom! Is this normal? just checking before I run the iron curtain with its bradder VCF and sestra Qotile.

Here's the Polivoks Modulator as master clock as well as its S+H used in a patch.
The Moffenzeef stuff all sounds great.

Humble Beginnings

Post by EliphasOfCascadia » Thu Feb 08, 2018 2:40 pm

super new to the modular world, wondering if I could have fun if all I had was a Harvestman Polivoks VCG and a MATHS to start? Looking to make a self modulating rhythmic ambient type system to play live drums to.
:help:

If Maths has a VCA then yes.

Recently snagged one of these for my dedicated system. I agree that I'd like to see it go a little slower if possible. I don't really care about being true to the original. Has anyone figured out how to mod these? I may hit up Scott at some point, but I'd rather not bug him. I imagine he's busy cranking out some awesome new modules.

Same Here as Master Clock Through Tempi ( Cool to have a initial Base Tempo)
Then can go as slow as i want Splitting the Channel on Tempi

Its Crazy as S/H Too Through Maths to have more control over limiting or augmenting pitch plus If you Run it Through the Kurzminogel after
Insane and some Malgorithm MK2 Madness to spice that up and why not wave shape through the King Slender while at it

Came here to see if there was a trim pot I could access to make the lfo slower. Guess not. Thanks for the answers though, guys. The S&H is great.
