Hello friends of the forum, first I wanted to say hello and tell you that it is a great forum for synthesizers, I am from Argentina, currently I bought a sh 2000 without working and I was able to put it to work, the only problem that I have not been able to solve is the Key off , that is, the keyboard turns on mute but if I play a key it doesn't stop sounding, I can play a new one, but it never stops, there is no key off, I tried to measure the transistors c 828, k 30 and etc but I can not find the error, does anyone know what component or components the key off= depends on? Greetings and thanks to all, they are great!

Well I already solved the problem, I didn't know whether to post the solution since I didn't see anyone interested in responding, but well in that case I'll do it so that someone in the future can eventually use this information, the problem was a tantalum capacitor that makes Key off or gate, in the VCA card, where it says ADSR, that was the culprit that did not turn off the sound when you stop pressing the key !! well have a great day and much success in solving those bugs !! hugs to all
