Analog XOR

So, I think I'm going to build a stripboard of this. It's tiny and will fit with minimal fuss in a rack panel with my SN-Voice pair. It really doesn't sound like anything else I have, it's cool and edgy.

btw.:
i have drawn a little pcb layout with Print mounted sockets and pot for Eurorack format. ( would also fit into a frac custom panel )
But it is without the CV input.

is that necessary ?

if anybody is interested for that _untested_ layout and _without_ the Cv input,
i can post it.
It is made with sprint layout 5 for which a read only version is free available at abacom

i will draw it with the CV input later.
On the actual layout there was no space to integrate it for fast
( the goal was the printmounting for the pot and the sockets because of fast building and much less errors )

ahh, it has 2 out sockets and one is with bypass switch ( that should also fit for a printmount switch )
ohh, and it has power connecters for Motm, Dotcom and doepfer.

I think you should post it.
Cool

ok, comments are in the file window

as sayed: absolutely untested.
Print it first out and check the circuit AND the spacings.
I will give it another look later ( maybe in January )
I'm into other projects now, and my frined who is etching for me has no time now.
this draw was just a spontaneous action Wink

here is the link to the free viewer software from abacom:

if the CV input is necessary i will redraw it then with that

Escuse my Noob schematic Question here but I stumbled across this circuit and really want to put one together.

My question is regarding the shape pot(?) in the top right of the schematic.

Does this mean the wiper of the shape pot is wired to the + 12 rail and the Input is wired to the ground??
very confused.

and regarding the power symbols generally.... When they point up does this mean the positive rail and downward pointing symbols represent the -12 rail?

any clarification would be greatly appreciated, just when i thought I'd gotten the hang of reading simple schematics, it seems there are many ways and symbols for similar things Mad

Glad to see this topic back on top! Smile

Ian, have you seen this? Probably, but i thought i post it anyway, maybe others have not:

I Do have a pair of 5pulsers though, so i need to build an Xor. What about the one on Ken Stones site?

http://www.cgs.synth.net/modules/cgs54_xor.html

will this work aswell, or Ian's is a special one?

Yes, I saw Roman's pulser some time ago. Very clever!

Ken's XOR works quite differently from mine. Would be fun to compare them side by side.

Very Happy

Ian

Just finished this last night, Ian was king enough to let me post the pcb, i will fix a few little things, the part labeling and post it. Added a mixer, so i can mix the Xor'd with the dry ins, it did make sense somehow.
Forgot to decouple the xor, doh. Very Happy

the pcb. i couldn't print now, so if somebody could verify if it's the right size,
or have a fresh eye for errors that would be nice. for the mixer section you need to refer to Ken Stone's page, also used with permission.

http://www.cgs.synth.net/modules/cgs04_mix.html

Also you need to wire in the mixer's in out's, bit self explanatory, but i can draw it if needed... i didn't buffer.

thanks to Ian, and pardon me my bad english. Very Happy
