Cgs synth

hello guys,

care to share any info or diagrams about Voltage Controlled Low Freq
Oscillator??

Im trying to clock it to my flanger circuit..... :-)

trying to convert RAMP to its exponential form..... could be done by
feeding the RAMP output(through a buffer) to its Cv input.....

thanks...

btw, much better if it doesnt use complicated parts...just common
parts pls....

I live in the Philippines and having a hard time finding parts....

c'ya... :-)
