Link VC Crossfader and panner

[fab]

Very interesting link for VC crossfader and VC panner with Vactrol or LDR + Led
http://www.simple-answer.com/DIY.html

I think there is a mistake in the crossfader schema :
for the 22k  (to ground,  the base of the fisrt transistor) , i put a 4k7, and all is Ok for me. I use a part of the crossfader shema to control pots, like the Tone God Rock'N'Control. I tryed the Tone God solution but for me this solution is better.

Hey, i search a schema for a linear capacitive sensor (not a switch).
well, like the probe... but not the probe..  :wink:

Cool. What were you trying to control with this ?

Ah Tone God - I see your number of posts is that of a well known opamp - 741!!!

With the VC Crossfader, forget the Opamp and the 2 signal In. Use the 2 ldr for remote control a pot (wah pot for example, in rack) like the Rock N Control for two or three pole and put the 10k pot on the scheme in a foot volume enclosure. On the schema there is another In for VC like LFO or other( the In next the 22 k resistor).
Personnlly I control all my Freq and Reso pots with that : The Uglyface Freq pot, The PWM pulse pot,  The TMK Feedback pot and all VCF Freq, Reso pots
All my stompbox are in rack.

:::Sniff sniff::: And that means something for this opamp freak. Now all I have to do is wait untill post #4558 then I can claim that I can make anyone play and sound like SRV. :lol:

Fab: So what did you not like about the Rock N' Control circuit that you like in this one ?
