I finally got this baby working :-) I changed the LM324 with a TL074, changed the other LM with a TL072 and put a 100k instead of a 22k. I used a SGS Thompson 4516. Apparently that other 4516 wasn't working. I think it was a Harris one, if their logo is an "H" ;-) Been playing wi

Hi Ken. I understand now. I did not understand how to install the 10k resistors, but after looking at the picture of the module I noticed you have them installed vertically. I know you mentioned this in your instructions but a picture is worth a thousand words. Maybe in the futur

Omit R1 to R6. Into one of each of the empty holes solder one end of a 10k resistor. The other end of these resistors go to the wipers of the six 500k pots. One of the outer tabs of these pots is wired to the other vacant hole left by R1 - R6 Ken > Hi everybody. I'm preparing to

Hi everybody. I'm preparing to build the Cynare Drum Sim and I would like to add the 6 additional pots to be able to adjust the shimmer effect. After reading the info on the site I'm a little confused on how to do this correctly. Does anyone have a diagram on how to wire this? Ha

Hi there Ken, been a while I know - and remote viewer of the forums - but thought I'd let you know I finally got round to getting the bandpass and matrix boards up and running with no probs (bar the everyday distractions and sorting out a power supply) and it's all good : ) tryin

Hi all, it seems that i built the Bi'n'Tic VCF correctly ( i get some "tones" out of it ), but - sorry for my stupid question- how do i test it in a setup ? I have a CV keyboard, another VCO, ADSR and other kinds ... Also to which should i tune ? It also seems that the COARSE 100

With lower freq stuff it doesn't seem to matter too much. I used a 3.3uF non-polarized cap on one, two polarized 2.2uF caps back to back on another. I got the idea from an LFO in Barry Klein's book, which I think used two 1 uF caps back to back. For a faster range, I would try th

2006-04-12 by Romeo Fahl
I did this. The 47n cap attached to the opamp labelled "integrator" is what determines the oscillation rate. I put a larger and a smaller cap in parallel so that I'd have three ranges to switch between. Pretty simple mod, actually. Take a look at Ray Wilson's LFO design for a vis

You cut the trace into pin 3 of the 4052 and insert the 100 ohm resistor. I didn't go look at the board, but I seem to recall that it is a long enough trace that you can cut it and brighten the traces on either side of the cut and just lay the resistor on with short leads and sol

Hello Ken mentions is his notes that if a higher value cap is used for the CX to place approx a 100 ohm resistor between the TL074 Pin 14 and Pin 3 of the first 4052, I used the .1uf polypropylene caps Richard Brewster mentioned on this forum (i am going to drop Richard's name al

Have you checked that the actual circuit-board trace is working at the 2.2 cap? When I built mine (which I was never able to get to fully work, alas), I found the traces to be very delicate and easily destroyed by only a couple of resolders, that is, they'd break where the trace

Still not getting it. I have been tracing my input though the circuit and i loose it entirely at the 2.2nF Capacitors. so i have no input into the base of the 2n2222. I have no idea what is wrong unless i have the wrong capacitors. Does it matter here what type of capacitor that

For reference: http://www.pugix.com/bottom-cabinet-lower.htm#synthacon Click the schematic link to get the GIF. BTW, it is not exactly 1 volt/octave, but it is in the ballpark. Both of my filters work fine. I beta-matched the transistors to get a similar response in both filters.
