I am wanting very badly to make an instrument similar to the Ondes Martenot.http://en.wikipedia.org/wiki/Ondes_Martenot
So far I have a basic hex schmitt trigger occilator that I want to control a pot with a string that will move the pot when a finger moves the string left or right. I also want to have a volume button that will adjust the amount of volume. I also might at the keyboard element to it, but it is not a must. Has anyone built anything like this. I'm still having a little problem engeneering the device that will control the pot.
