What are your 5U plans for the weekend?

[cornutt]

First of all, nice work! It looks great.

MOTM-990 6-pin distribution panel for all the digital modules that never were,

I've actually got three of those. I made them the standard distribution in my MOTM/MU mixed system. I wouldn't mind having another one.

[synthetic]

Oh that’s an interesting idea. I’m planning to keep my MU and MOTM modules in separate cabinets. I bought one in anticipation of the 5U CG and MT that never happened. But I use it for the 650 MIDI/CV converter.

Wiring the two systems sure shows the differences in power distribution for the two systems. I always though of MOTM as the superior format but I’m coming around to the Dotcom power idea. MOTM uses twice the connectors. That’s added cost, and twice the opportunity for things to go wrong. (Like being plugged in one pin off, not that I just did that…) Dotcom’s “just bundle everything together with a wire nut” is not as elegant, but once it’s working it seems less likely to go wrong.

Well it wasn't originally in the plan for the weekend but I saw something that gave me an idea and the next thing I knew I had a new module;

I added a CGS04 mixer to an MFOS VCO which gave me a VCO with a mixable waveform output. Plenty cool!

[electricfence]

That’s a nice-looking, interestingly-featured VCO.

Nice! Love the dual V-OCt jacks! Hopefully you used the red part of that CGS04 circuit aka attenuverters to more than double its available output. At least on the Saw-Ramp. Or use pull pots to invert the WFs. Yes, it's worth it.

Very cool. Didn’t the E-mu oscillator have a waveform mixer like that?

(I know, but I don’t know how to type “mu” character on my iPad)

I was curious so I figured it out, at least one way to do it, basically I just added another keyboard layout. Here's some details:
https://support.apple.com/guide/ipad/ad ... 19a/ipados

You can just lightly hold the keyboard selector button (emoji button) to get a popup and then select "Keyboard Settings"

Click the number of keyboards arrow

On the next screen click Add New Keyboard and then select the Greek one from the list. You should then see it in your list:

and then back in your app you should be able to select the Greek keyboard and type the character:

@ electricfence - Thanks. It works pretty well. I like being able to mix up a wave shape before sending it to a filter without having to muck about with a mixer.

@ synthetic - I'm not sure I know the oscillator of which you speak. The feature is a pretty simple one so I wouldn't be surprised.

@ kss - I thought about using the red schematic features but in the end I just wanted to build the module quickly. It was a 'concept to prototype in one hour' sort of thing.

I had an old 2MU MFOS VCO that I wanted to convert to 1MU but I didn't have an extra stooge panel to build the 1MU version. I saw someone did something similar to this with an MFOS board so I figured what the heck and gave it a try.

Just curious, but is this something that you plan to make available for purchase, or is it just for your studio? (No pressure.)

Eµ MODULE 2200 oscillator http://www.siliconbreakdown.com/emuoscillators.htm

Also Seb slipped a mixed output into his version of the Moog 901 (the Moog and Synth-Werk versions don't have it):

The ARP 2500 series 1004-P (P = Pot?) VCO has a variable waveform mix out and the 1004-T (T = Toggle?) version just has toggle switches for a Inverted_On-Off-On unity mix output?

And various ARP 2500 hard/soft cloners seem to mainly go with the "T" version:

Yes. DPR definitely drew on the 2500 for his own modular!

Yes, the P and T are Pot and Toggle.

And various ARP 2500 hard/soft cloners seem to mainly go with the "T" version:

Yes. But not all.

Nice! T and P together!

Last night I received a LWSS DUSG. This weekend I’m going to find every possible way to use it in my Moon rack. Should be fun!

[Flareless]

Just curious, but is this something that you plan to make available for purchase, or is it just for your studio? (No pressure.)

I wasn't sure there was any interest in it beyond my own. I can put together a product page for those interested.

Stay tuned...

Awesome! It's such a fun module.

There are some great examples in our Tips & Tricks document (page 11).

Here is a playlist of DUSG demos by Todd Barton.

Enjoy!

Great, thanks!

Edit: I sound like Tim Blake now. I can rest.

Maybe this will be helpful for someone else. It seems that just about every time I've made a cable, it was using microphone cabling. But I just bought 100' of Mogami guitar cable (2524) to make some patch cables. But 5 out of 5 of the cables I made were bad. What the hell? I recently wired a 96-point patchbay with only two errors and now I can't solder a guitar cable?

It turns out that guitar cable includes a small inner PVC jacket. There's the outer jacket, shield, then a black PVC inner jacket before the clear jacket that's around the primary. If you don't strip this black PVC off, your cable will suck because it transmits to the shield and if a tiny amount touches the primary it will make that short. I had never encountered this because it's not on the mic or AES cable I usually get like Mogami 3080. It comes off with your fingernail or a greenie screwdriver and then everything works.

Very helpful info! Thanks for sharing

Update:
This is fantastic!
I really don’t know how to explain or describe this, but adding the DUSG changed everything!
It’s not new to me, and certainly not to this community, but sometimes a module or a function just seems to gel with something in me and causes even the most clueless tweaking to produce actual music. I’ve tried using the DUSG as an envelope, as a clock and clock divider, as an oscillator, as a psychotic LFO, as an envelope follower, and more, often several of these at once, and no matter what I patch its outputs into, I end up with something musical. The last time I had that same sensation was when I babysat my buddy’s Buchla easel. Everything I did with it turned to music.
It’s quite odd, too, because I’ve had Maths in my Euro for a couple of years and half expected the DUSG to sort of *be* Maths, but in my hands, Maths and DUSG turn out to be surprisingly different beasts.

Everything gets better with slopes.

I use a lot of Gotham GAC-1 in my studio for synth and guitar cables. About 2 1/2 100 meter rolls over the last 40 years.
The black sleeve is used on that cable as well. It is conductive plastic similar to what's used in some potentiometers.
I think it's probably there to make the cable quiet when physically moved?

The first cable I made was a short circuit because the sleeve touched the tip terminal in the plug.
It was a confusing thing for a minute. I thought I had melted the insulation off of the center wire... Then I tried trimming off that black sleeve.

I just thought the jacket itself was black.

never was an issue with me, but good to know as sometimes I have to troubleshoot an iffy cable.

Could be. I'd bet it's there to provide 100% shielding which is not possible with typical braiding alone.

Shielded cables designed for plenum aka static use often use a metalized plastic foil shield with a drain wire for the same reason. 100% shield. This is arguably more important for a plenum cable than for most moving cables as they are laid in next to each other and may not be easily accessed for inspection or repair.

And because it's far cheaper to buy and make up foil and drain than braid. Belden calls their version Beldfoil.

The foil shield is great as long as you're not moving the cable around. Once you do that, the foil breaks up and degrades. Eventually leaving yo with a really low shield percentage. The cable makers know that this is going to happen and using the drain wire helps to keep the broken foils bits electrically connected to preserve as much of the remaining shield as possible.
