Hey, I just noticed the MOTM 650 has a clock inside. One more reason to buy that puppy. :) On May 14, 2008, at 8:58 AM, Jeff Laity wrote: > I'm working on one now. I'll post a bunch of pictures once it's > completed. I'm still deciding about the pots to use. I think I'll use > go

I'm working on one now. I'll post a bunch of pictures once it's completed. I'm still deciding about the pots to use. I think I'll use good-quality ones (Spectrol 149 or 249) since precision is important (for pitch). However, this thing is going to be awesome once Paul finishes hi

Ken @ Richard, Thanks for your replies! I'll put an attentuator after the CV In since the quantizer *should* be at the output it's fine to attentuated non quantized signals from e.g. my noise source without an output attentuator. My brief testing with an quant. signal suggests th

Hi Dave, The Bridechamber panel is more or less laid out like the CGS Seq Switch. It adds a glide circuit before the outputs, which means a trace needs cutting. Each jack is normalled to 15V, so that the module works as a normal sequencer when no inputs are used. With the inputs

I've used quantizers on the ASR inputs. There is a slight DC offset that's a little different on each of the three outputs. But sometimes the results are quite acceptable: http://pugix.com/synth/chords/ I've got four quantizers now, but six ASR outputs! -Richard Brewster sasami@.

Awesome, thanks Ken. I found the previous discussion about this issue and rewired the module to use the toggle switch as recommended. I also changed the R-GAIN resistor to 1.8k as the output was very low compared to my other drum modules. This seems to have almost removed my issu

When there is nothing connected to an input to the AND gate, the pull-up resistor will pull that input up to +10V. If you plug in something connected to ground, the input is now at 0V instead of +10V. >--- In cgs_synth@yahoogroups.com , sasami@... wrote: >> >> >pulldown resistors

It will limit the AND gate output to 0V. If another input goes lower than 0V, the output will also go lower, but it will never go above 0V. >So, say If I have two signals patched into inputs 2 and 3 of the AND >gate, and the attenuator that feeds the envelope generator output int

Hi. I'm building a clone of the buchla 281 function generator which is basically a set of voltage controlled attack-release generators where each pair has an extra OR output. I have chosen to replace this OR output with a CGS Analog Logic Board so I can also have the AND function

Hi Phil, they are still germanium diodes. Not all of the diodes I had from those computers looked the same. The very latest batch actually used new germanium diodes because I ran out of the vintage ones. The sound remains the same. Ken >hi Ken, >it appears the RRMs I just receive

Hi, 2 things. Firstly, I found an old post about adding LEDs to the outputs of the pulse dividers which presented this schematic: http://www.ph.k12.in.us/~drew/cgs36_led.JPG Since then, the board has undergone a revision and now the resistors (from top to bottom) are 1k5 then 1k.

My mistake! The DIV by 2 outputs are acting just like your graph. I at first didn't understand how the outs related to each other. Is it possible connections 4A and 4C are swapped, 4C goes high when reset and 4A low. --- In cgs_synth@yahoogroups.com , sasami@... wrote: > > > I'm

Ken, I've stuffed and installed the new divider. No errors that you didn't point out on your web site. But at 0 degree the divide by 2 out is changing state on the rising edge of the input while divide by 4, 8 & 16 change state on the falling edge (I haven't checked the other pha

What you have done sounds correct. First discconnect the wire from RSS and see if you still have problems. Yes - you've disturbed something else. perhaps investigate the input stage. Did you swap the LM342 for a TL074? No - you are picking up nise through your wires. Try adding a
