Yes, something is certainly fishy with my filter, so I went ahead and ordered the kit from Elby out of d.i.y. desperation. Thanks, I will look through the archive... Adam Schabtach wrote: > > If you look through the archives of this mailing list, or (more > simply) look > at the

If you look through the archives of this mailing list, or (more simply) look at the comments by John Loffink at the end of the page on Ken's CGS site about this filter, you'll see that some people have found that the frequency control has too much effect rather than too little. T

Sorry - can someone send me or post the frontpanel layout for the CGS VCO. I need the full functions of the VCO thanks
2005-11-13 by betweenpie
Well, my first attempt a +/-15 device - a Steiner filter - isn't going so well. Seems the frequency and res controls have little or no effect, depending on which input is being used. I will keep tweaking, however. I'm quite new to this, although I've built a number of successful

Adam, where do you get these threaded stand offs, Liquid Steel epoxy, nuts and screws? I'm very interested. This might be a solution to my problem. Cole --- In cgs_synth@yahoogroups.com , "Adam Schabtach" wrote: > > I haven't done the VCO, but the Ken Stone PCBs I have seen vary
2005-11-01 by Adam Schabtach
I haven't done the VCO, but the Ken Stone PCBs I have seen vary quite a bit in size, so I don't think that one can make a general statement one way or the other regarding their fit behind a 1U panel. FWIW, I like mounting my PCBs on threaded standoffs attached to the rear of the

Will a Ken Stone PCB fit flat, behind a MOTM 1U panel? I'm just wondering, because I'm figuring out how I will mount the VCO PCB that I'm working on. Thanks, Cole

Arg - these so-called "laws of physics" of the "real world" ruin my best ideas. :) Thinking about this however, made me realize that the Gated Comparator is just a few simple modules (white noise, clock, another comparator (maybe 2), solid state switch, some voltage sources) away
2005-10-23 by sasami@hotkey.net.au
I think you would find that the S&H caps would prevent this. You would get some sort of signal through, but way reduced, as these caps take quite a while to charge up. You could reduce the caps I guess, but that would make it worthless as an ASR. Yes it is bipolar. Ken >Yeah, it'
2005-10-23 by xamboldt
Yeah, it's not designed for processing audio, but it does handle bipolar signals, right? I imagine it would sound very nasty processing audio, dividing it into narrow slices (grains) - although to have an output resembling audio it would have to be clocked very quickly, so it mig
2005-10-23 by Richard Brewster
The ASR is a CV processor, not a signal processor. I haven't tried clocking it at audio rates. Obviously the clock would come through very strongly in the output. Feedback is a useful principle in general though. If you mixed one of the outputs together with the input CV it would

2005-10-18 by Adam Schabtach
You can obtain just the breadboard itself for a lot less money, and you could either use your modular's power supply or buy/build a bench supply. Total cost would still be less than that package. You won't need both +/-12 and +/-15V supplies (one or the other--probably 15 if you'

Look carefully and you will see two different frequency modulation inputs. CV1, CV2, TUNE, and the 1V/oct inputs are the exponential inputs. These are the normal ones you use to make the VCO follow a keyboard, etc. These are DC coupled (no capacitor). It is the LINEAR FM inputs t
