MC,
You’re an EE so I figure your the best person to ask. I have been looking for a hardware sequencer for my Voyager. I found a pretty cool synth called a Revolution from a manufacturer named Future Retro. Here’s the link:

My question is: Is the sequencer in the Revolution compatible with running the Voyager (CV and/or MIDI)?
Thanks!
MIDI, no question.
CV is 1v/oct so they are compatible.
However the gates are not compatible. Revolution gate output is +12v, Voyager gate input is +5v. I would not recommend a direct connection. If you have a CP251 you can use an attenuator to drop it to +5v. Or you can design a special patch cable with one plug wired as a voltage divider, it’s only two resistors. There should be plenty of net references on voltage dividers, start with Google. That stuff is EE101 material.
+12v gate is a good design idea as some vintage analog synths (ARP) use a gate this hot - for lower gate levels it’s a lot easier to attenuate it.
That Revolution has one hell of an interface 
MC,
Thanks for the information. I do have the CP-251 so I’ll keep it in mind.
