Im planing to buy the RS200 modular step sequencer (among other things) from Analogue Systems to sequence two Slim Phatties. But the sequencer sends out a 10 volt trigger/gate(?)-signal. (the phatty-manual specifies only a 5 volt gate input..)
I cant find any info on whether or not the Slim Phatty works/survives with a 10 volt gate input in the long run.
I could buy the cp251, but it would just sit inside a rack being used only to attenuate one gate signal, which I think is a waste of money if its not absolutely necessary.

I also tried to find some decent info on the different types of gate signals; gate, pulse, trigger, s-trigger, etc.. I read somewhere that Moog-synths are a little tricky in this area.(?)

Im only familiar with moog-gear so far. This is my first step into the modular world and Im spending all my money on this, so i kinda hope it works the way I plan.

Anyone with some knowledge out there??
Any info is appreciated

For attenuating duties, a simple potentiomer/resistance can do the job, I guess. I let the technical details to specialists though.

I just read the Theremin Plus "manual". It gives an example on how to use the gate-output(which is 10 volts) to trigger the Little Phatty gate-input.

I suppose 10 volts is fine.

Good stuff!!

I've emailed moog support some month ago with a similar question.
Here's the answer :

Theoretically, the Slim's Gate jack should be robust enough to handle
+15v. However, I don't recommend doing this for prolonged periods of
time. If you plan using this setup regularly, then a CV attenuator is
an excellent idea. Anything below +6v or +7v, should be safe.
Let me know if you have further questions and take care!

Btw it's really easy to build a DIY CV attenuator.

Thanks.
I suppose I could just make one myself.
An input socket, an output socket and a 50K linear pot.. Does that sound right??

Absolutely.

What about shifting/offsetting the 0-to-10-volt-gate 5 volts down to -/+ 5 volt???
In one of the modules Im ordering there is a "shifter" which Im not really planning to use for anything else.
Any thoughts on that?

Well, as long as your input signal is below +6/7v you should be safe no matter what

Thanks.

Very curious as to how the filter sounds processing audio when the external input gain is increased...

How did this work out for you? I use the MOOG CP-251s...the Voyager XL, in Eurorack; a Bubblesound LvL+RM module and various other mixers/mults from Analogue Solutions, Intellijel, Manhattan Audio, probably Doepfer...

Very curious about the Analogue Systems Comb Filter module and how it compares with the Moogerfooger Clusterflux and Delay units ~ also concerned that they require a different power supply from Doepfer
