Does anyone have any experience using an old 1970s technology CR-78 rhythm machine with the Voyager? The CR-78 has a trigger out and I'm wondering what use I can put this to. For example, can I run it into one of the red CV inputs without blowing anything up?

The manual says it's a "Trigger pulse out, OFF: OV / ON: +15V pulse, trigger pulse select switch: 8beat, 16beat, combination". Whatever that means.

You sync the MMV's LFO. Trigger the EG's

Cool, I can see where that would be good times. Is the fact that the trigger out is 15V and the MMV says the ins are 5V an issue?

With a CP-251 you could lower or boost the voltage.

Ahhh, things are starting to click, slowly...but clicking. So let's say I got the VX-351 (which I don't own yet but probably should get). Is it possible for me to send the trigger out of the CR-78, into the attenuator to drop the voltage, and then somehow use the mults as a splitter to send the trigger signal to my moog's LFO, perhaps some other CV in as well, and say an EchoPlus (5V trigger-in) sampler pedal? All the jacks on the 351 boggle my brain a bit...I see the 4 mult outs but not sure how you send a signal in to split.

Yeah you get it. Some outputs are for audio and some for CV. Sometimes audio signals can modulate as in the case of a LFO.

By the way the chubby analog sound of a cr78 sounds great with the voyager. I've been sending an extra line from the 78 into the voyager's mixer input, overdriving the channel, adding filter, plus some Memory Man Delay...you can get some real crazy sounds going, insta-drum-remix moog style. Just got a Murf and want to try controlling the rate with the 78's pulse out but too worried about blowing something up so I'm going to wait to get that attenuator!
