Received the pcb today Fonik, real spiffy looking, hi-quality as usual.
Thanks.

Hi,

Just finished the PCB, all looking great!

I was wondering whether there is an option to hook a LFO LED on the board so see the rate and depth of the LFO...

i built the CV circuitry within my electronics workbench software and did some measurements. according to my findings i made a little spreadsheet showing the different values for different PSU settings.
i used four measuring points: 1st right before the potentiometer to set the initial CV (R16/19/22), 2nd the output of the voltage reference (emitter of Q7, controlled by R29), 3rd and 4th the voltage reaching the LEDs and the vactrols (now saying that, i should have measured the current, i think???).

here are my findings (without any warranty):

any comments by the more experienced appreciated!


hey,
finished my resonators today, and just wanted to say that the above stated works great for 12V.
now i am just waiting for the frontplate, then i will post some pics and soundfiles.

big thanks for that great module fonik!

Whomper

the LEDs for the CV channels actually do just that, assumed the LFO is routed to these...
otherwise there would be a need for an additional off board LFO driver.

Got my boards about 2 weeks ago (I think Smile). Really nice looking!
Started soldering yesterday. Missing a few bits and pieces though.. made a order for more components today. So hopefully I'll have it done by like begining of june..

My frontpanel layout (I'm not 100% sure about it - might need the dry/wet pot..?).

i've seen some of your panel layouts before, and one must admit they are not only beautiful but seem to be instructive and functional, too. Shocked

the wet/dry mix is just a goody. i don't use it at all. mine is always set to wet. in general i tend to split signals before different modules and then to mix the processed signals later.

Nice! Perhaps skip the LFO OUT in favour of a DRY/WET pot?

Anyway, seems like the whole world has gone resonator crazy!
Micas are sold out at Banzaieffects and Vactrols are sold out at Farnell/Newark... wonderful! Laughing

I need all the LFO OUT I can get. So I'm keeping it! Wink (I mean, it's just a triangle wave - but when i feed it to my CGS wavemultiplier it's gonna be something completley different when it returns Twisted Evil )

Micas sold out from Banzai Shocked Cwap! I hope they've recived a new shippment by the end of the month, when I'm gonna order micas and vactrols from them..

Oh, the silver micas were cheaper! €1.40 i/o €5.12 (from banzai!). Thanks!

Yep, they say they will ship mine in mid May.

Vactrols lead time at Farnell/Newark was a sad story though - don't expect any VTL5C3/2 from them this summer! Shocked Luckily Banzai still had theirs. Smile

these are 100V rated instead of 500V, i guess. they are much smaller and will fit the PCB as well (the footprint provides different sizes).

No, the micas at Banzai are €1.55.

Ooops. I realized the ones I was looking at on Banzai had an extra 0 before the pF Embarassed Glad I didn't order.. Very Happy

Too bad, you would have ended up with the world's first BASS RESONATOR! Laughing

Btw I'm thinking of adding some extra capacitors and a hi/mid/lo switch to each of the three resonators in order to make them cover the whole audio range. Any similar experiments out there?

I had something like this in mind but didn't know where to start.
Actually I wanted to do it to be three different ranges. Lo, mid and hi.. without switch. But with switches it would be sweet.
So, C8, C10 and C12 are the ones to change values?

Yep, that's what I expect. And I guess they don't have to be micas.
(The micas are only chosen in this design because the original had them, or am I guessing wrong?)

spot-on!
actually any non polarized cap would work.

Good.
My plan was to use micas in the normal mode, and then switch in some suitable other caps in series/parallel to raise/lower the resonance frequency ranges. We'll see what happens. Smile

I was thinking of on-on-on switches from c&k (hard to get in croatia) but I'll better use rotary. Or maybe I'll stay with original design. Don't know yet, just thinking.. Smile

SOLD OUT!
just sold the last spares. thank you all.

however i would be very interested in seeing and/or hearing your finished projects. i already uploaded some pics of finished modules of the 1st run to my site and would be glad to add some more!
(not only resonators, but SSM2044 VCFs, attenuverting mixers and TH super controllers as well! - email to fonik-at-web-dot-de)

here's my front panel for ps3100. this one is without modification.
matthias what is your next project? count me in for one or two PCB Very Happy
cheers

This is probably a very elementary question, but, how does one measure filter frequency? Say you drop in a cap, and you want to measure the range that this cap gives the filter. If the filter doesn't produce a tone, or self oscillate, what are you measuring? Perhaps the effect on another tone or noise signal?

If you don't mind, I'd be very interested in knowing your progress. I bought 2 PCBs with the intention of splitting them up into 6 ranges. But other than just dropping in different caps, I don't know how to proceed.

I have a book, by delton horn, on modular synth construction--and he has a band pass example that looks pretty close to this one (without vactrols naturally) with a set of equations for determining cap and resistor values. I'll post a picture of the page it if anyone is interested.

Hi,

I tried to search the forum by could not find a reference to the power drain of the module.

I am looking for this info to calc PSU load.

Thanks,
