Hey Ken! I've got the zero and span controls nailed for the VCO of the Bi-N- Tic and the response through the v/oct input is now where one would expect. Also the range of the VCO is very wide. After quite a bit of experimenting, it still seems that the bandwidth and damping contr

more 4006 fun! In the US, check out Halted Electronic Supply at http://www.halted.com/ccc1073-cmos-ic-s.htm - they've got the 4006 for $0.49 US. That's not too bad. If there is interest, I could request a quote for a large quantity just to see what they come up with. Chub

I'm chuckling over something I noticed in the Synthacon VCF instructions. In the first paragraph, Ken says "Its sound is quite unlike Moog ladder, has a lot of character." But then in his tweaking notes, John Loffink says in his last paragraph "This is a great filter ... with lot

Hey all, Does anyone have a sample of the ASR modulating the pitch of VCOs? I'm having trouble grasping exactly what this module does to CV and that would be the best example for me to hear I assume. If you do, can you post it up for me to hear or point me to it? Thanks, - Michae

I was going to use Eagle but I think I'm going to use DipTrace instead. Their pricing structure is better suited to my needs and I like the user interface a little better. However, the only PCB software I've used previously is the free one from ExpressPCB, so take my opinions wit

I like to use 35-36mil holes with 60-65mil pads. I just realized I haven't been following that rule to closely, but the bigger hole/pad makes it easier to solder. I have those sizes on most resistor, capacitor, diode, and DIP IC footprint. I'm fixing the footprints I have that do

i've used a few places. I pick one depending on how many I want and how big the board size is. Usually I only get single boards made so that limits things. I just can't justify buying 5 boards when I only want to build one, and it might not even work. but sometimes the price diff
2005-06-23 by charlesosthelder
Well, that was quick! The 10K resistor at the 1 and 2 pins of the 4011 wasn't connected to 0v solidly. Now the Sub Osc rocks hard! For the uninitiated, even one channel makes for a very big sound! No exaggeration is possible here - Ken's design is killer! This has plenty of seque

Ack! Virtual ground! Have I forgotten everything? I'd already gotten my answer earlier, though, as the B channel works well now. The A channel isn't so cooperative. There's nothing past the second opamp stage. The diode tested okay and there's a feeble (just over the noise) signa

Can anyone point me to a good service to get some PCBs made? I have used the ExpressPCB mini board service. They'll make three boards for about $60 USD, as long as the design fits certain criteria. For larger quantities or other sizes they are much more expensive.

2005-06-21 by Michael
It seems like it would be a pretty simple thing to turn the cv cluster into an octave switch for a VCO. CV in is 1v/oct Mod in is not a jack but a constant 5v source. Switch the outputs to a single jack and you have octaves. Does this seem feasable? - Michael nil-x

Yeah, that's my Bionic Filter : ) It is indeed a Schaeffer panel, or rather it was done by FPE. The layout is part Wiard 1200, part Buchla, part other. I haven't posted the .fpd file, but I should probably get around to doing so. Soggy --- In cgs_synth@yahoogroups.com , "arithmad

Hi all! The NTE devices *are* really spotty but I've had about a 50% success rate with the NTE4006. Also tested in my circuit were A and B series RCA and TI units. The success rate was much better (though I only had 6 to test then) but there's no guarantee that any one device wil
