I’m sure a similar thread exists, but with 56+ pages of threads…
I’d like to hear peoples thoughts and technics in CV/Gate patching, configuration and combination. Share your Ideas and config’s and the results of all that experimentation. Plus I could use all the advise you can spare with my own set up.
So far I have…
Little Phatty w/ CV/Gate add on.
MF-104Z Delay
MF-107 Freq Box
MF-105M Midi Murf
MP-201
2xEP-2
An army of patch cables.
So many patches, so little time.
I don’t understand…
Normally you start from a single CV/Gate source, like an analogue keyboard, an analogue sequencer or a MIDI2CVGATE interface module. All devices with a CV/Gate input can be fed with that, even in parallel provided the input resistances of the devices are not too low and the expected polarity of CVs and gate signals fit to the incoming values.
If you want to feed multiple sources of CV/Gate into one destination you can mix the CVs in a DC mixer stage, but you get a logical problem with the gate signal (AND / OR).
Perhaps I misunderstood you totally…

I would get to know each pedal’s CV ins and outs on their own. Some parameters have a knob, so the cv in for that does the same thing as turning it. The CV ins without a knob you can get to know using your ep-2s. The CV LFOs on the MP-201 can now automate any of the knob tweaking and pedal work. The midi LFOs on the 201 can be programmed to modulate just about any parameter of the LP.
Patch the CV-outs of the foogers to your LP filter or pitch in and see how different settings on the fooger change the sound of the LP. Try patching to other fooger CV-ins.
As far as routing the audio … try them all and write down the configurations you like. Or don’t write it down and just enjoy it for the moment.
You’ve got a powerful setup there. A CP-251 would be really useful, if just for the Mults (but really for so much more).
There are a lot of videos on my YouTube channel that could give you some ideas. Here are a few in particular.

I’m really itching to get a CP-251. I hope to find a used one for a good price.
Question: If a CV out is split into 2 different ins on say a Fooger is there any loss of control, or range?

Depends on the input resistances of the CV ins. If they are high enough, there should not be any difference. But you have to check it out. If there is an audible loss of frequency, the 1V/Oct behaviour could be in danger also. In this case you need an additional buffer stage for the CV.
Thanks Carston, plenty of research and experimentation to do. That’s really why I started this thread is to build info and get advise. As a chronicle of ideas, do and don’ts, results of whacky experimentation, because I plan to run cables every which way. Clearly if you all are building Moog System 55s and such you’re likely the people to learn from…
Question: Is there risk of doing damage? For instance I had thought of taking a Little Phatty out and looping it back into itself, but I hesitated… Etc.

Well, I don’t know the Littlle Phatty, but looping back Audio Out into Audio In of the same device can result in an incredible noise … I would not do that. And if you do, you should attenuate it cartefully, like the manual says.
I did this with my Simple Delay Module of my Formant Modular, and I had this loop back effect which nearly killed my ears…

Not the Audio out, a CV out, say the Mod, then back to a CV in like the pitch or something…
That should work. My Korg MS20 does the same. But isn’t there a direct way of controlling the pitch by the mod?
I wouldn’t bother with routing the audio out back into the input. This trick works on the Voyager but the LP has the filter Overload parameter built in.
One thing to try is to take the Freq box’s OSC output and plug it into the LP’s Audio IN. Then take the LP’s pitch CV out and plug that into the Freq box’s frequency CV IN. Now you’ll have a 3 OSC LP! 
I dig it. Speaking of the audio in, I can put anything into that? Say my Les Paul? Would I need a preamp in between?
