OK, the ARP Pro Soloist and Pro DGX are very special beasts completely different from all other ARP models. Because they are digital. OK, partly. Yes, they really are. Both the memory switching and (most important!) they keyboard CV are handled digitally. Which means that most likely the described faults are not in the keyboard CV generation but in the "master oscillator".
