MF-101 Envelope Out Question

I feel like a dumbass asking this one, but I gotta ask…

Can the CV from the Env Out control the Pitch CV input on a Voyager and track it halfway decently???

I’m thinking mult the Env Out CV, use one of the mults through the Lag filter and an Attenuator for a Gate and another straight through for Pitch and I should be able to play patches with a guitar. The lag would make the Gate adjustable for length and the Attenuator the amount. I guess you could patch it through the mixer on a 251 and fine tune it more.

I gonna be bummed if I could have been playing the Voyager with my guitar for the last year…

I have a 102, 104SD, VX-351, and CP-251. Just hit me tonight the 101 might have an Env CV Out so I checked and voila!

If the MF-101 will track a guitar closely enough to play a Voyager, why doesn’t Moog promote that idea???

Also, it seems if a Gate CV out was added to the 101 you’d have an instant analog synth-to-instrument inteface.

The envelope out on the MF101 won’t let your Voyager track your guitar’s pitch. The envelope on the 101 follows your guitar’s amplitude, not your guitar’s pitch. If you send the envelope out to the Voyager CV in, the Voyager’s oscillators will track your volume, just like the MF101’s filter does.

The ENV out will work as a gate voltage without any processing on alot of synths.

If you want to track your guitar’s pitch, you’ll need a Pitch Follower, which are few and far between. There have been alot of posts on this Mooger board about this topic and about how Moog should make a Pitch follower as the next MoogerFooger.

Thanks for the reply.

I thought I needed another CV.

Synth.com makes an instrument interace that tracks pitch, amplitude, and outputs gate. With a power supply it’s probably $250.

I wonder if he could put one in a single horizontal rackspace…

That Synthesizers.com Instrument Interface module is an Envelope Follower also, it’s not a Pitch Follower.
It’s pretty much the same thing as the MF101, but without the actual filter. I don’t think Synthesizers.com makes a Pitch Follower yet.
There really aren’t very many. If you’re interested, you can look through the old posts on this board, and you’ll find alot of info and lists of the various Pitch to Voltage/ Pitch Followers that have been made. Most were made in the 70s.

synth.com does sell a rack mount frame, and you can use their wall wart power supply to power the modules. It fits 8 modules, and takes up 5 rack spaces.
I’ve been thinking about ordering one with some filter modules for a while to use as a rack mount signal processor, but I don’t like the idea of having to wait 2 months to get it (which I think is their typical lead time on orders). no patience…

If you’re ready to start going down the modular route, check out the Analogue Systems RS-30 module:

Analogue Systems RS-30 Frequency-Voltage / Envelope Follower

I haven’t used it so I can’t say how effective the tracking is

Wow, that’s pretty cool. I also started looking at some of their other modules and I really liked their functions. It looks like this system is very strong for sound processing (having this P/V module, trigger generater, lots of filters, etc) and synth-percussion type uses. Which is exactly what I want from a modular system.
But, I hate that “euro” modular/doepher-style design with mini-jacks and cheap little plastic knobs. I don’t think I could bear it.
That’s one thing that’s so great about the synth.com modules, they’re so much more ergonomically/aestetically pleasing (to me anyway) than the average modular… and the price is great… and they supposedly sound good too.
I wish there were stores where you could go play equipment like this… and vintage equipment…
there used to be a couple synth stores here in NYC where I live, and it was the best thing in the world to be able go in there and play synths side by side. I could go play an SH101 next to a MiniMoog or Arp Odyssey and finally understand why one costs 5 times more than the other…

I haven’t looked too much at the modular stuff (not financially viable at all at this point…), but the downside for the dotcom stuff for me was that there weren’t as many options for cv control. For example, with the doepfer you can get a regular adsr envelope generator or a voltage controlled adsr; not that you’d always need or want this extra cv control, but I really like the flexibility (especially since I wouldn’t plan on using a keyboard). When I looked at the dotcom they didn’t offer that extra level of control.

I’m with you about ergonomic aspect, although I’ve never actually used either manufacturer’s equipment so can’t say if either is/isn’t what I’d want.

The voltage contolled ADSR; Yeah, that is pretty great. You could always add that one Doepher module to a Synth.com system. I think they make power suppy adapters and so on for this purpose.

As far as sound goes… who knows. it’s pretty hard to tell just from listening to samples, right?. But people seem to like the Synth.com stuff. I’m sure Doepher owners like Doepher too. Although from what I’ve read about their filters, they seem to use IC designs, more like 80s synths. Synth.com doesn’t really disclose what their filter designs are based on. Other than the “Ladder” LPF.

Have you ever seen Modusonics? They’re the old Moog Music based in Buffalo. When Bob Moog bought the rights to use his name again the old Moog Music (which never really went out of buisness) changed it’s name to Modusonics and they’re still around. You can buy newly manufactured 70’s Moog products from them. They sell Moog Modulars, Bode Frequency Shifters, Mood Vocoders, etc. I only just heard about it, but apparently they’ve been doing this since buying out the “Moog” company from Norlin in the mid 80s.

hmm, that’s interesting. Not a bad price on the RS-30. Anyone seen any demo mp3’s online? :sunglasses:
