VX-351 multi outs

How do you setup the Source of the multi-outs?

Any light on this topic?

Thx much!

There is no setup necessary - a multi is simply a group of jacks that are connected together. This enables a control signal to be sent (patched) to more than one destination.

yes I understand that part. But how does one know what the SOURCE is? Or better yet, how does one DECIDE (if one can do so) what the source will be for the MULTI-OUTS???

The source is whatever you plug into the multi. The source could be any CV on the 351.

The mutli simply allows you to route the same CV to multiple functions.

I'm trying my best to keep this simple as possible.

I understand the concept that the multis are for using 1 CV output to control multiple CV parameters on the Voyager or a MF. Lemme know if I'm off.

My question is this:
Since the mults are not labeled, I'm assuming they're all outputs. However, how does one know what CV parameter is controlling whatever I connect the mults to? Is that determined in the Voyager's Control Panel?

OK, can you describle how YOU use the multi-outs?

This is open to ANYONE.

Thanks so much for you patiences..

ahhh! wait

Is this done via the attenuator I/Os? The manual seems to dodge this portion of the 351.

The mults aren't "strictly inputs" or "strictly outputs". They're just a bunch of jacks that are wired together.

You plug a signal into one of 'em and it comes out all the others. You plug two different signals into two different jacks, and they come out the others, mixed.

The jacks don't "know" what's plugged into them. Think of them as a Y-jack, if that helps. Or think of the mults as a big bucket of water with 4 hoses in it. You can send hot water into the bucket via one of the hoses, in which case you'll be able to siphon out hot water with any of the other hoses. You can send cold water in via a second hose, and then be able to siphon out warm water (hot and cold mixed) with either of the two remaining hoses.

Imagining signal flow as water flowing through pipes and hoses seems to help sometimes, if you're unsure how things are connected.

MMV Users Manual p. 63 wrote: WARNING: A mult is NOT a mixer. Do not apply more than one CV source or CV ouput to a Mult! Combining CVs in a Mult can cause them to add together in a way that can be damaging to some control inputs! Don't do it!!! You must use a cv mixer, like the CP-251 control processors's Mixer to combine cv outputs.

Is the manual accurate?

As an example of what will work, you can patch the triangle LFO output on the vx351 into anyone of a mult's connections and then use any of the remaining 3 connections to send a cv signal to the pitch, filter, and/or, volume inputs on the Voyager.

ahh ok, I see now. The 'hose' theory does the job. :+)

so simple, why couldn't it be said sooner?

anyways, thanks

ouijasaucer:

The manual is right!

Never sum multiple voltages together without knowing exactly what you're doing. And if you do do it, I never told you to do it, see?

Ideally, you'd want an attenuator on each of the mult jacks, which basically turn it into a passive mixer (sorta). Well, okay, it's a passive mixer already, but this turns it into a passive mixer with level controls.

Anyway, it's probably not a good idea to be summing CVs together with a mult.

Unless you know what you're-- ah, forget it. Don't do eet, man!
