SX-210 eighth note problem

2016-03-25 by pero.stranac@...

Hi everyone, I'm new to this board and very happy it exists! :-)
Recently I bought a SX-210 in very good condition. The battery is still original, no leaking yet - but I plan to change it next week.
The tape load/save works great, so I downloaded some patches from this board.
But, on some patches there is a problem: when I play only white keys, one after another (C scale) every eighth note has a different release then other eight before.

For instance: If I start with C2, than C3, D4 and E5 are affected.

Could anyone explain me this?

Thanks, regards, Peter

I am guessing it doesn't matter that you are only playing white keys.
Assuming that voices are allocated in sequence, every eighth key that
you press will get the same voice each time.   Sounds like the release on 
that one voice has an issue in the VCA envelope generator circuit.

First thing would be to figure out which voice it is, then start troubleshooting.
