The Mimetic will give you CV voltages and even a gate out. But, it's not the easiest device to program in a live situation. If you save and store your patterns, then you'll be okay as you can load them on-the-fly.
If you plan on setting up your patterns live, you might want something that has traditional analog faders or pots.
I would also suggest at least one dedicated quantizer. The Disting can do it. But I would definitely NOT recommend the Disting in a live set-up unless you can set it up before your set begins.
Also, Lugia once recommended to a Eurorack mixer with cue mix abilities. Perhaps he'd be kind enough to tell you about it as I don't remember the name... But you might be better off mixing on a traditional mixer that has pre-fader cues as you'll be mixing Eurorack with your line-level hardware synths... and finally, MUTES. DivKid just released a vactrol controlled set of four mutes built to avoid audible pops when switching them in or out. You can use the mutes on a traditional mixer for audio. But if you're trying to mute CV, then I'd definitely look into the DivKid mute module.
