I'm in. It would be great if this goes through.

I would be all over a the stereo resonator PCB!

I've been laying out the framework for a new 'prepatched' modular for about a week now and I was planning on including the resonator in the output stage - however I was wanting to use 'separate' L|R channels (kind of like the dsi evolver).... this would be icing on the cake (along with JH's new 'subtle chorus').

powered up the double-x-panner proto tonight. just looked at it on the scope, and from what i saw it worked fine. the VCAs just did not close 100% but that's okay for a panner.
tomorrow i will hook up a PS3100 resonator to it. i'll keep you posted...

Yeah! new resonator boards, put me down for one stereo set

Did I say I was interested yet? I'm up for a set when they're ready.

i hooked the test PS3100 up to the panner/fader and it worked quite nice. unfortunately i had no possibility to record some sounds. but believe me, this board makes a monster out of the resonators. i will build a version with patched out connections, so that the panner/fader is usable as a stand alone unit. hopefully i will be able to post some samples next week.
at least a short video (without sound due to old fotoapparillo) showing the x-fade-panning of a triangle and a squarewave on the scope.

BTW when i am ready i will start a new thread asking for interest. it is to early to start a list, i think (i will redesign the PS3100 PCB to make it double trouble x panner fader ready).

i just finished the new PCB design for the PS3100 and placed an order for a prototype. it will provide a switch for invertion of the LFO for the 3rd resonator, but neglect the wet/dry mix. one OpAmp is left and it's pins are brought out to pads. so it could be used for an additional wet/dry mix or whatever you want.

i am not sure if i can get this all done before christmas, but i will try...

here's a preview:

Wow. I know you're not taking a list yet but put me down for a couple!

here is pic of the partly stuffed front panel, in order to make the features more visible (3U, 20TE Eurorack):

the LFO is normalled to the three resonators CV inputs, the LFO for resonator 3 can be inverted. by plugging an external signal into the CVs the LFO gets overridden.
while there is still an mono out (all three resonator signals get simply summed, each resonators signal is normalled to one of the x-fader/panners input.
Input C (center) goes right through the submodul and gets distributed to the Left and the Right output. The signals on inputs L and R get cross faded/panned to the outputs. the panning can get controlled by the resonators LFO, manually and/or by an external CV.

can't wait to finish the module and upload some samples (will take a while, though).

>>today i did a sketch of how the panel could look like (in fact mine will look like this), in order to make the features more visible (3U, 20TE Eurorack): <<<

It looks like you've been rather busy, Matthias!! Very Happy

It looks really impressive!! I can't wait to hear some samples, or better yet, get my hands on a couple of the PCB's!

Be sure and keep us posted on your progress!

sure. as soon as i finished the prototype module i will start a new thread containing the description and some samples of this module. then we could determine interest in PCBs... i am realy busy these day. i was not able to discipline myself, so there are currently quite a few projects on my workbench (and i will see the workbench only once a week). however, the PS3100 stereo resonator has priority 1 now.

This looks great, I'd be interested on a PCB too.
Thanks!

just wanted to let you know, there is some progress. the prototype PCB arrived at least:

how are these coming along? I'm thinking of buying the vactrols for these in advance

So, this PCB is all in one, with the PS3100 Resonator and Panner circuit all together, right?

I have two PS3100 PCBs from one of the last fabrications that I've yet to panel. But now I'm thinking I'd much prefer this new circuit with the VC Panner on board. This will make a really powerful module.

Not sure what to do with my old PS3100 boards however.

I think another very cool possibility for this new super-PS3100 is as a sheppard-tone generator by feeding it a three phase LFO to the three different CV inputs, or maybe taking two of these boards and sending them a 6-phase LFO. Hmmm....
