Vintage Synth Repair

Hi, new to the list. I have two questions pertaining to an ARP Axxe

1) It seems to me that the CV Memory needs alignment or repair. If a
note is depressed and released, the pitch slowly climbs. If the key is
depressed and held, the pitch remains constant.

2) When a key is released, occasionally the note will release and
sound again. I've yet to look at how the keyboard functions, the
schematics show a switch, but I am not sure how the switching was
implemented.


Any help and guidance would be fantastic!

Thanks,

Mike Hunter
