Check out the Files link- Coyote4.mp3 is a pretty good grinder sample. Also, the grinder will be more subtle on various waveforms. I don't have the module, but the grinder circuit makes sense. A chip with a low slew rate will make all the difference. Maybe if you just bought ten

Hi Adam! What IC are you using? From a brief look at the archives, it seems much has been discussed about finding the best sounding IC. Usually, LM358 with poor slew are the best choices. If you've got a socket on the pcb for this IC, it would be best to simply audition all your

I am also happy with my recently completed Wave Multiplier, although I am somewhat non-plussed by the Grinder section. It seems that its two controls have basically the same effect on the timbre, although with slightly different ranges of operation and some interdependence. It al

hi there CGS builders, I have several CGS bandpass filter modules and enjoy their sound greatly. Does anyone know if it is possible to get other filter modes ( HP or LF) from points in the circut? I know SVF have all the responses availbe, but I am not sure if the CGS BF is a sta

You may need to clip a couple of legs off the MAT02 depending on the version of the PCB. The legs are "n.c." anyway so you won't miss them :) >I think I bought mine here: > http://www.digikey.com/scripts/DkSearch/dksus.dll?Criteria?Ref=454740&Site= US&Cat=31786109 > >yea, thats d

One reason to choose Curetronic was simply because they are so cheap: Before I ordered the other Curetronic (Kits!) I tested the ADSR and found that module to be very good: Very fast in the fastest mode and extremely slow also possible with a very nice exponential shape I was loo

Thanks for the reply. I have seen Ray's Single Chip Sample and Hold. There were some notes on FETs there that may be helpful. I am trying to get mine to work with +9V rather than a bipolar supply, which means Ray's elegant design is not wholly applicable. The +9V also is why I wa

Same as the resistor it replaces - i.e. 50k for the pot (47k for the resistor - the difference is insignificant), or if you want more gain, you could use a 100k pot, but you do run the risk of clipping at higher gain. >hi, > >thanks. just one more question I overlooked, what >val

I've actually found that despite the TL072 not going to its negative rail, it is better even single rail situations, depending on what the output is driving (e.g. CMOS is fine). It seems the LM358 specs are all over the place. Some are good and reliable, and some have very poor s

That connects the DC mixer to the power. The power is already linked between the bandpass boards, so, no, you do not need to run a wire like that to each bandpass board. Ken >directly next to where the beads go on the cgs30 pcb, theres a link. > >i'm stacking a bunch of bandwidth
2005-08-18 by Richard Brewster
I have substituted the TL072 for the LM358 in many CGS comparator circuits with good results. The one place you probably should not do this is when the power supply is not dual, i.e. pin 4 is grounded instead of -15V. The LM358 handles the single supply better, I believe. For exa

Thanks, Ken! You nailed it. Actually, both of the things you pointed out were wrong. The previous owner had installed a 1uf cap instead of a 1nf cap on the RC filter. I changed that, but the problem persisted. So I swapped out the LM358 for a TL072 and the problem vanished. I mus
