Window Comparator

Post by zerosum » Thu Aug 07, 2008 11:20 pm

I would be interested in *HEARING* or seeing what people are doing with theirs, I have read about it, and it didn't really turn the lightbulb on in my head untill I this:
I think one that doesn't get enough credit is the Window Comparator.
The Improbability Drive uses a window comp. to create digital noise, but having a Window Comp. by itself is SO much more useful.
It can of course be used to craft your own digital noise or merely destroy an audio signal. It is extremely useful as a modulation source when clocked. It can extract triggers and craft cv into gates with variable width and level!!! You can turn a Sample and Hold (quantized or not) into a variably fucked up CV controllable Clock!

Comparators are great for extracting gate signals from a CV source. One could use the Window Comparator on the output of a sequencer to get an "accent" gate when the CV output was in a particular range.

And of course they'll square-up/fuzz-out any audio signal.

Sorry, no audio here. IMO it isn't the type of module that lends itself to that as it is usually providing a utility function that might not be immediately discernible in a patch.

I ordered one from AH. I'll pick it up in 2 weeks and have it installed, next to its brethren, by the last week of this August. I can flop some sound files up here then. :sb:

if you got the cash just grab it. cheap and well worthwhile. i can't wait to get the kit as it looks like one of the most fun to build in the blacet lineup.

you've seen blacet's video of it right?

Is the window comparator what I think it is?

It outputs gate(s)/trigger(s) signals based on a set threshold of an incoming voltage source?

Sounds like it may be more complicated than that. That video just confused the hell out of me.

oh man. i totally realize now how much of a noob i was. when this manual first got put on the site i had zero idea what the fuck it was talking about. upon reading it again just now i basically understand everything the manual outlines.

so fucking sicc. i can always use extra gates, and i've been hungering for gate delay. if i ever get the wiard noise ring sorted i'm getting this next along with the binary zone.

Binary Zone + Window Comp. is a magic combination.
I built the WinC first (and it was useful even by itself), but coupled with the BiZ! yummm. Their oriphaces are super compatible.
I'll post demos soon (probably too busy with work until Monday).

Thanks for the great responses everyone! :mrgreen:

Yeah I saw the video and manual, I just wanted to see these concepts applied in a patch(well technically the video IS applying these concepts in a patch).
I ordered one from AH. I'll pick it up in 2 weeks and have it installed, next to its brethren, by the last week of this August. I can flop some sound files up here then.

Thats a good point.

:sb: Thought so, Im sure they will get along just fine.

Demo!

Post by Cat-A-Tonic » Sun Aug 10, 2008 10:40 pm

Here is that Window Comparator demo that I promised.
Maybe I'll do some others to show off its other uses.
In this patch it is mainly being used to process the Sample & Hold Quantized output of the Improbability Drive for use as a drunken clock for the Binary Zone. I imagine this is not so far off from what a Source of Uncertainty does. I am stoked to get my WoggleBug #3 finished to see how that compares.

I'll give you the rest of the patch details later.
I have to go to work now.

Thanks for taking the time to post this :sb:
Its given me ideas and an understanding of how I could use it in my system.

So it went something like this...
ID quant out to WC in,
WC trig out to BZ clock in,
BZ inv out to VCO v/oct,
VCO sine to Dual Lin VCA split A left & B right,
VCAs panned by EG1,
WC inv out to EG1 gate in,

Here is where it gets a little crazy...
WC ramp out to ID level cv,
WC out to ID width cv,

Added and subtracted the following patches during the recording...
ID dig out (OR body contact) split to WC ramp cv + WC level cv,
VCO saw to MiniWave in,
MiniWave out (OR body contact) to WC width cv.

I tried to keep it pretty simple, but hopefully the additional variations kept it as interesting for you as it was for me.

Thanks for prompting me to do a demo. I was thinking about it, but it sure does help to have a little push to know it's wanted. 8)

Rad! Oh man, those are cool.

I just got an M17, and it's similar. similar. The ramp out is cool, but the width adjustment is just so cool.

Another one for the "frac expansion list". BZ, MW, WC, NR

Here's another one

Post by Cat-A-Tonic » Tue Aug 26, 2008 9:46 pm

I made another demo using the Window Comp. in a really complex feedback network with XOR XNOR Logic, VCO, Gate Delay, and Binary Zone. This is also periodically being used to VC the Mini-Wave.

http://share.ovi.com/media/Cat-A-Tonic. ... onic.10005

It really show-cases the Mini-Wave as a clock source in comparison to the previous demo of the Window Comp. shaping the Quantized S/H into a clock source. It is almost more of a Mini-Wave demo in a way.

We should probably consolidate these threads.

Window-Mini-W-Clock Patch Notes

Post by Cat-A-Tonic » Wed Aug 27, 2008 8:52 pm

God DAMN! Have a pic of this patch?
Hmmm, pile of black spaghetti?... not sure how easy that would be to follow... How about some notes instead?
This is the gist of the patch. Knob, modulate, and season to taste.

Dual Lin VCA is stereo output, panned from EG1.
EG1 gated from Gate Delay.
Gate Delay In from VCO Pulse Out.
Gate Delay 'Slew Out' (AS envelope) to Window Comp. Gate In.
VCO Saw to Mini-Wave In.
Mini-Wave Out to Binary Zone Clock In.
Binary Zone Inverted Out to VCO 1V/Oct In.
VCO VC Wave to XNOR Logic In 1.
Binary Zone Out to Window Comp. Ramp CV.
Window Comp. Ramp Out to XNOR Logic In 2.
XNOR Logic Out to Window Comp. Level CV.
Window Comp. Inverted Out to Dual Lin VCA In A(B).

http://share.ovi.com/media/Cat-A-Tonic. ... onic.10005

You could skip the EG1 and just send both outputs of the Window Comp. to the Dual Lin VCA. Lots of options. Try it out and post your own version.
All of the variations you heard in the recording were done by switching the Mini-Wave into different modes and injecting it with CV from the Window Comp..

I guess now that I think about it this shows the Window Comp. as a VCO.
