MOTM

Hello everyone,

I have a few really basic questions, since I am going to be expanding my system the next 
few months, I want to understand some stuff:

1) If I use a Pro-2000 there is one Gate output and one CV output, but lets say I have 4 
EG's and 4 VCO's, where do I get the rest of the Gate and CV signals? Can I just split the 
outputs? Use the Aux outputs? Is that what the Cascade Panel is for?

2) Lets say I have 4 VCO's going to 4 different Filters. How do I plug them all into one VCA? 
Is that what the Motm 830 & 890 are for?

3) How and why would someone use a second or third VCA?

4) I'm going to make patch cables. Does it matter if I use balanced or unbalanced patch 
cables?

I'll appreciate any help, just to understand the concepts.
Thanx,
Ithai B.


P.S. Maybe it would be cool to have a FAQ document for this site group, with various Q&A 
just for MOTM, beginner and advanced, since perhaps many have the same questions. I'll 
take on the job of compiling the questions and posting them. That is if anyone is 
interested.

1.The Pro2000 has 2 dedicated CV and Gate outputs. The 6 auxilary outs can be assigned to transmit  V/oct and Gate. This means with one Pro2000 you can hook up a total of 5 pairs of CV/Gates.
 
2.You would want to use a MotM mixer to mix these signals of course :P. If you don't have the MotM mixer modules you could always use a standard mixing board, remove the signal from the main mix bus and then just use an aux send to get the 4 signals mixed into the VCA. 
Basically outputs from filters --> 4 mixer channels --> mute the channel from the main mix bus --> send the 4 channels to 1 aux send --> input on VCA
 
3. The reason why I use multiple VCAs are for several reasons. First I can configure my modular and Pro2000 so that I can use an OSC > Filter > VCA setup on several MIDI channels so that I can have more than one sound coming from my modular. Secondly, for percussion sounds you may want to use a VCA to change the volume of an OSC and a noise generator independently. This would require an envelope generator for each VCA as is the case with the example I gave before. Another use for multiple VCAs would be if you are trying to set up an FM patch (DX7 style) where the carrier and modulator each need independent control over volume. There are a plethora of other reasons for having multiple VCAs but these are the most common things I use multiple VCAs for.
 
4. I would recommend making unbalanced cables if you plan on using patch cables for your modular since the MotM modules 1/4 jacks aren't balanced. The only reason you would need balanced patch cables would be if you had a balanced patch bay. If you plan on using them in a patch bay as well as your moduler than it wont hurt to use balanced cables but you wont benefit from them on your modular.  Unbalanced connectors and cable is less expensive. Word of advice: if you are making unbalanced cable with cable that has a shield and 2 conductors DO NOT solder both inner connectors to the "tip" of the cable. This can cause capacitence and reduce high frequency response if I'm not mistaken.
 
Hope this helps!
-Chaz

Get in on Larry Hendry's next cable run (maybe he can pipe in on when 
that will be.)

Seriously, I did the math and the difference between making your own 
and buying his comes out to like 50 cents per cable.  When you factor 
in the time it takes to prep the cable and solder the ends on, they are 
actually cheeper.  Plus you get all these different choices of cable 
colors.

Look for a cable announcement in just a few days.  I need to firm up prices
and update the website.  The price of the connectors we use has gone up.,  I
think it will add about 30 cents to each cable.

Oh, but that's the fun part!

Am I the only person in the world that enjoys making cables?  Really, 
it's like knitting or meditating - very relaxing!

Yes you are!... sorry I'm guilty too a I have a 750 foot spool of canare and I have to keep 
restocking on conectors. Neutriks are about 90 cents at redco.com not $3.00 like 
everywhere else.

70 cents for NYS-224's in 100 quantity or more at fullcompass.com.

The Pro2000 can't really do polyphony - you could use a keyboard with  2 
zones each outputting different MIDI channels that correspond to the  CV/Gates on 
the back of your Pro2000. The only thing is that you would need to  have the 
same patch programmed for each "voice" and you would have  to play intervals in 
seperate octaves on the keyboard (cause of the  zoning you would have to do, 
see ghetto ASCII graphic below). It would  be kinda funky. As one of my 
teachers said "Who the hell  needs polyphony anyways?" :). There are other MIDI to 
CV convertors out  there that can operate polyphonicly but I can't remember 
what the names of  them are. I'm sure some other MotMers would be able to help 
you out with that.  Keep in mind also that you can always record multiple 
monophonic lines as audio  into a sequencer and layer them together to achieve 
polyphony. Obviously  this wouldn't really work for a live gig but it will get the 
job done.

Very helpful Chaz! Thank you... Now I understand also how to take advantage 
of the Pro-2000.
 
 So, how would you achieve Polyphony? Even just 2-note
 polyphony?
 
 Best,
 Ithai.

I made almost all the cables for my studio. Belden and Switchcraft. It 
is not that difficult. I don't find it as relaxing as building synth 
modules though. I view it more a necessary task. They look nowhere near 
as cool as the Stooge cables though. I hope to get some of these for the 
synth that will be in use all the time.

Cables are no place to buy cheap junk. When I needed to buy some when I 
had no time to build, I chose ProCo. Well built. Cheap cables don't last 
long and troubleshooting a complex patch just because of a faulty cable 
is a big time waster. So little time to create as it is.

Done ranting, Scott E.
