Hi this is my first post. I'm hoping it will be noticed by SYOTR. I would like to be able to switch back n forth between normal and variation rhythm on my ctk7000 via a foot switch. Is it a simple soldering job as with rotary speed control ? Would I need 2 foot switches ? What is the purpose of the 1000 ohm resistor ? Any help much appreciated. Regards David 😁
