Hi. I purchased a Moogerfooger CP-251 Control Processor a while back because I wanted to experiment/take advantage of the CV/GATE IN/OUT on my Little Phatty Stage II. I was wondering if any of you could tell me if any patches using the Little Phatty Stage II CV/GATE IN/OUT with the CP-251 Control Processor can be potentially "harmful" to either the Little Phatty or the CP-251? I've started experimenting with the pair, having a lot of fun, tons of fun, but a little apprehensive still, just don't want to potentially ruin/burn anything by patching anything "incorrectly". I would "cry" if my gear got ruined. Can any of you help me. Am I good to go, patch away, learn more as I go? Or are there certain patches I should really avoid trying?
I've used modular equipment before but just basic vco/lfo/adsr/vca/etc, have never really used things like attenuators/mults/voltage mixers/etc.
Thank you very much!
P.S. Any Patch ideas/tips (using the Little Phatty Stage II CV/GATE IN/OUT + CP-251 Control Processor) would be awesome! Thank you!

Re: LP II CV/GATE IN/OUT + CP-251 potential harmful patches?
Just be careful with the Mult because voltages are additive. I've used the VX-351 Mult (which is the same as the CP's as far as I know) to add voltages and I think most of the Moog inputs are protected up to about 10V but anything higher and you can do some damage.
OSC's (in the Voyager for instance) go silent when the Wave is pushed beyond the range... so if you try and affect a Pulse width modulation from the higher end of the square wave north, you'll hear the OSCs become silent. I think the circuitry can take it in general but like I said, try and stay below 8-10V. Otherwise, don't blast a super hot signal into an audio input that isn't protected. The Voyager has a lamp to show the heat but the Phatty does not and now way to attenuate internally.
It's always a good idea (but seems somewhat unconventional) to wire up a 1/4" to an inexpensive multimeter.

@emwhite
thank you for that.
but I don't understand still. why does the cp-251 have more than 1 mult jack then? do u know what I mean? does that make any sense?
I might just not be understanding exactly what the mult jacks do or are used for exactly. sorry if I sound like an amateur. the mults are used to distribute voltages to other different sources right? If that is so, maybe I need an example of what a basic/simple patch that utilizes the mult in a RIGHT way would be, and an example of what a patch the utilizes the mult in a WRONG way would be. I think that would really help me maybe.
Thank you all so much. I really appreciate it.

Not intended to derail the thread, but what are you guys using to monitor voltage?

Multiples are used as passive signal splitters, i.e. you plug in volume envelope CV and can distribute that out to three other destinations if you have a multiple with 4 jacks.
What is considered as 'harmful' by some is using it as a signal unity 'mixer', i.e. put in more than one source of CV and take that out to one destination.
Control voltages would sum up since they are connected together. That could lead to a really high CV which would damage the destination possibly and could also lead to unexpected behaviour.
Rule of thumb: Connect outputs to inputs only, and inputs to outputs. Never input to input or ouput to output.
And use only one source in your multiples. Plug that into the upper jack (or leftmost jack with white circle on the CP-251), and memorize you can have that signal three times now.
The three remaining non white circled jacks act as outputs.
Its controversial if damage would occur. Some have reported damage, some patch away like crazy. Always depends on your signal level and specs of inputs/outputs.
But better be safe than sorry, imho.

@dualaud
Thank you so much. That really breaks it down a lot more. That's exactly what I needed, a basic/simple breakdown.
So 1 input jack for the mult and the other 3 jacks act as outputs.
Really, that really helped. I appreciate it. It is much clearer now.
You broke it down simply and logically!
Thank you again!

Glad I could be of help!
Have fun!
