A new member of the Prophet family

Hi folks. After many years of searching, I finally have my Prophet X.

So, I was incredibly disappointed when my first boot gave me the dreaded “Cannot reach audio processor”.

I’d been reading the forum in preparation and checked the 2032 battery — 3 volts on the nose. I restarted and it booted fine. I was happily swimming in the new‑sample kingdom when I got a high‑pitched squeal and then the interface froze. Bah…

I have a support ticket in, but being a nosey parker, I reseated all of the headers, the ATX connectors, and the PCI bridge. Success. It appears to be happy now. I’m sure cargo transit isn’t ideal for a sophisticated device like this.

Are there any obvious sanity checks I can perform before I commit to it?

While you have it opened, check the DC voltages, I had to tweak my 5 volt supply up a touch to fix USB sample import issues.

I set the Power Supply Unit just under 5.2 volts DC to get 5.0 volt reading at the USB sample import port.
