Hi!
On MiniKorg 700s there is a vibrato speed potentiometer 50KB and you can choose its destination: VCO (vibrato mode) or VCF (travel vibrato). Unfortunately the rate of the potentiometer is too fast for a nice slow LFO, the slowest frequency is about 0,7 Sec. /cycle. So I'd like to decrease the starting rate. The pot is wired between +20V and ground. I've tried to put some resistor around but when the voltage decreases the rate is increasing. My electronic knowledge is little so I hope someone have an advice.
Thanks for any help.
Greg
