hey !

is a sample and hold circuit also used for the CV Keyboard if you release a key - so the oscillator wont get high (or low) while the release time is still heard?
or is there an easier circuit to do this? or just a capacitor on the right place?

thanx

Good question! Analog keyboard controllers have sample/holds built into them so you would not need to use an external sample/hold with your keyboard.
