and how do i have to solder the 1uF decoupling caps ?

vladosh · Posted: Wed Aug 31, 2011 11:57 am Post subject:

in the layout there are already 100n ceramic capacitors that serve as decoupling caps .. but if you wanna add those 1uF electrolits you can use this .. for orientation .. there is a nice paper on capacitors i know it's on the fonitronic site i think it's called 101 capacitors http://www.modular.fonik.de/files/capacitors_101.pdf may wanna check it out ..

here's a proper layout with the strips cut off in the back ..
cheers

about using it commercially if you think .. that's for MFOS to decide as for the layout you can use it as much as you want

Seems a good place to ask; whats the difference between a passive and a buffered multiple Embarassed

Thanks

I read someone comment once that when more than one vco is driven thru passive multi - there is a drop in voltage ..meaning out of tune , i don't care too much about such details for now as i'm using no tempco vco's anyway ,so i use a passive multi .. with buffered there should be no problems like that .

What's the 20K resistor for? It doesn't seem to connect anywhere

I saw this thread seeking for buffered multiple tips and also found another schematic from Ray Wilson online. See attachment.

Wondered which one I should choose. The one attached or the one seen in this thread. More detailled here:
http://www.musicfromouterspace.com/analogsynth_new/OLDIESBUTGOODIES/VOLTAGEMIXER/voltagedist1.html

Cause the one attached looks more recent, has attenuator pots and has less components, caps etc. ("more simple" in a way, though the other one is not complicated).

Mostly I was wondering if I would have to change any component value for 15V supply use instead of 12V.

Also if this could be used without problem with audio signals as well... Not necessarily mixing AC and DC signals, but using this module for both uses.

I like the buffers from this project of Ray's:

http://www.musicfromouterspace.com/forums.html?MAINTAB=SYNTHDIY&PROJARG=CVANDGATEDIST/CVANDGATEDIST.html

I built a utility board that includes both the gate/trigger distribution and the CV distribution portions of that, one with and one without the voltage offsets.
