my OS #243 crapped out 3 weeks after i got it home with the keyscan board failure. moog shipped me a replacement board directly (took a week to get to me) and i installed it and was back in business in 20 minutes. an easy fix.

That IS the keyboard scanner. Just email amos and he will probabvly send you one. I don't know about the OS, but for the Select Its just a matter of unscrewing about 15 screws. Youll have to unscrew the LCH panel and disconnect 2 of those wires. THen youll have to turn the Voyager upside down, unscrew the bottom, remove the keyboard, uynscrew the scanner and then replace it with a new board. Then do everthing in reverse and your OS willbe brand new.


But yeah, the Oscs playing at a low voltage....thats because they are receiving the lowest possible voltage from the keyboard.
Amos will provide you with more detailed instructions and your Voyager will survive the surgery without any scars.

You shouldn't have to ship your voyager anywhere, but since yours is an OS I don't know what they might tell you.

Shoudl be a very quick fix though.

This seems to be a common problem with the OS.

Mine crapped out 4 days after I got it :(

the OS has 8 screws that hold the keybed in place that need to be removed, along with 2 screws holding the pitch/mod wheel assembly.

once you get the keybed up (the keyscan board is underneath it), 4 more screws hold the keyscan board in place.

it's pretty straightforward and simple.

Are Voyaer OS keyboards dropping like flies? Do I need to keep a backup keyscan on hand or is this a common part? If I go Rip Van Winkle I might wake up in a world that has no keyscan parts, and that just won't do.

Amos asked me what the serial number was.

I think Amos told me something like this on the phone:

"We produced a run of Voyagers that had some bad keyscaners. Im going to send you another one that has been reprogrammed so it won't fail after that." After that particular run of Voyagers, they fixed the problem.

He sent me the piece and I mailed him back the other one.

Easy as pie.


The Real Amos might get on here and give you a more accurate reason than the one that I pulled from my memory banks.

Yeah, it's definitely not the lead in the Chinese solder or the Chinese asbestos the PCB is made of. :lol:
