Alphabet Soup

Post by parasitk » Sat Dec 20, 2008 1:26 am

James/Carbon111 just posted about this on the Serge Yahoo Group:

Carbon111's Serge Modular Webpages wrote:Alphabet Soup #1: The DSG

The DSG is one of the most flexible synthesizer modules ever conceived and yet in some ways is very simple. This is first in a series of introductory articles, each focusing on a particular Function Block.

That was really cool, but I'm still not too clear on how the envelope follower and suboscillator functions works.

the Bananalogue website wrote:Sub-Harmonic Generator

If a series of triggers are applied to the VCS faster than the total rise and fall times, the module will divide the incoming signal by a whole number. In the audio range the output will be the sub-harmonic series.

Hope that helps on the Sub part! I've done this with my VCS and it's touchy and interesting to tweak. I've never tried the Env Follower trick though...

That's awesome :love: Every frac setup should have a rack of 4 VCS and 2 3P :sb:

yeah the VCS was a real gem for frac and euro--a slice of serge heaven for the commoners. too bad they're gone now.

Yep, I really want a second one. Hell, and a WVX Wave Multiplier as well.

I second that. I could use one or two more VCS' surely. They're damn useful in so many varied ways.

The envelope follower is just relying on the portamento/slew limiter functionality. I haven't actually tried this with other slew limiters, but in theory with the right rise/fall settings, it will output the average amplitude of the input signal, giving the "envelope shape" of the input signal. Although, now that I'm actually typing it out, it needs to be a unipolar output (no bipolar) so the VCS/DSG must be doing something special there.

I'd really like to see James (Carbon111) do the Smooth/Stepped Generator next. I'd interested to learn about any patch programmable functionality that I've no doubt not wrapped my head around yet.

Ask him! He said on the Serge List that he's looking for suggestions!

It's been done. A three part series starting here.

Wow, I saw James' email pointing that out too. As often as I've gone through the serge-fans site recently, I can't believe that I missed those! It's certainly changed my mind on the usefulness of the SSG. Wow.

I missed that as well, however I'd still like him to cover it!

Well, I can tackle the envelope follower part. :tu:

With both the "rise" and "fall" pots set very fast, the output will follow the input waveform very close...pretty much just making a copy of the input at the output.
With the "fall" pot set to a longer time the voltage will just follow the peaks because it has no time to drop down...giving us an overall shape of just the top of the waveform, which is the same as the amplitude envelope...which is what we're trying to extract in the first place. :)

BTW, hi guys!

I'm overjoyed that people have found my synth pages useful, that's exactly why I do it! Cheers! :beer:

...And a heartfelt thanks to Muff for such a cool forum! :sb:
