What CGS filter to choose? Subject description: Band-pass or Bi-N-Tic? |
|
|
Hey!
I'm designing a four panel system with mainly CGS modules (I'd like to keep it all CGS, but can't since it lacks an envelope and a few filter moduels...). But anyway.
I've come up to the point where I'm about to choose between 4 band-pass filter modules or one bi-n-tic filter. I've built them both. So it's just a matter deciding which one it will be.
(Now you'll think; he's got 4 panels! Why can't he do both.. Sorry! it's either the one or the other... since mainly all the other panels are full with lots and lots of other stuff! Just to say that panel no. 2 holds first 4 x topps buchla 281 and then the CGS modules - digital noise, saw pitch shifter, VCA, pulse divider + xor, VC divider and then a 4 step programmer sequencer... And that panel is just 4U x 17" so it's 16 columns with 8 rows..)
Anyway.
Pros and cons!
Bi-N-Tic: Nearly all the demos I've hear on the net doesn't make me want one. It just doesn't sound so cool! The thing that gets me going is that metalic ringing that it has? I really like that part. The second reason why I want one is that I think I can do some really unusual sounds with it, both metalic and more "droney" sound.. There was one demo on youtube that was OK.. But it's always hard to tell, since most of the videos is just a mischmasch of alot of things going in and out of the module.. And it's hard to tell what kind of sound it actually makes.
Band-pass: It's not CV controlled, so it doesn't benefit from being close to a VCF altough it's not. I like the idea of being able to set it up as a 4 output into 4 different VCAs and then use some kind of quadrature modulations to get it to sweep between the filter points... That would be a sound I'ld like! A small bit electric drone, but yet acustic.. But I'm not sure it would be usefull in "real" music. But I like the idea!
I know it's hard to choose between apple or pears. And I really wanna be conviced that the Bi-N-Tic is something worth having... But so far I'm not sure. And I just made a sketch of the band-pass filter on panel no. 1 (which is where either one will go) and it looks damn nice!
I'd really like your honest oppinion!
Maybe I should make a pol?

Sounds like its going to be an excellent modular
Which CGS filter?? - Steiner!!!!!!
It still rates as my favorite filter, especially when the CV source is a super psycho LFO.
I like the BiNTics and use them a lot (have 3), but tend to use them as unusual VCOs and I tap the extra outputs of the 4024s for the divided frequencies. A great module but not really a 'normal' filter.
A BP filter bank is on my to-do list, the one on Ken's page looks so good. If you had one of these and wave-shapers/multipliers/manglers, you probably wouldn't need a VCF. |

ditto what andrew said. the steiner is just a great filter, very distinctive voice but does all those filterey things straight up. you can do a very compact build, as well: my standard has one input jack and 3 toggles to enable LP BP HP or any combo, haven't really missed having separate pots for each.
the bi-n-tic is more exotic, i also use it more as a source than a filter, and as far as i can tell it cant be "tamed" very much. cool stuff, but you pretty much have to want that sound, that's what it does. for timbre-shaping, i'd go with the wave-folder ahead of the bi-n-tic: very very versatile module... it would be a toss up, for me, choosing between the steiner/wavefolder.
i also have a 5-up bandpass, but the lack of VC really is limiting. unless you already have some good LPFs on one of the other panels, and really need some subtler formant kind of voicing.
4u, 19" panels... sounds sort of sergish? would love to see what yr planning... good luck!

I just built the Synthacon, and having separate inputs for HP, BP & LP is really worthwhile, because it gives you the interpolating scanner effect, which sounds incredible. Having a different source in each input makes very strange sounds, amost like sequencing through each input, with the filter changing subtly or a lot, depending on the setting of each pass.
I also have a CGS band-pass, although the resonance isn't working properly. It can sound similar to the BP on the Synthacon at it's most tame. I really like the bandpass...I think it comes down to what types of sounds you want to make. Multiple bandpasses would make for nice string sounds, plus you should be able to put a DC mixer linking them without too much more space. Despite mine not working properly, it also makes a nice treble-like eQ. Having four, and panning them, should allow you to extract & layer four different frequencies from one sound. |
