I think my Old School needs recalibration

I’m not quite sure, since I’ve only had it since May, and I have not had this happen yet. I was listening to some Kraftwerk, and decided I wanted to jam along to “Ohm Sweet Ohm” off their “Radioactivity” record. I realized that it sounded fine when I’d play toward the left side of the keyboard, but when I got up to the higher end the pitch started to drift badly, and it was no longer in tune with the song. I investigated further, and played a tuning pitch from my DAW. Yep. If I tune the Voyager to a high D and play a low D, it needs to be tuned again. What would you all recommend?

If you’re wondering, I’d had the Voyager fired up for about an hour at this point, so this is not an issue of cold oscillators.

Does it do that for all 3 oscillators ?

and filter res at zero? sounds like a mothership trip to me…

Kenneth, if it’s still under warranty, better send it to Moog Music. If not, here’s the tuning procedure for all Voyagers: (just scroll down the page until you reach the long post by Revstate)

In most cases, only the keyboard scaling will have to be touched (mentioned in the very first part in reference to an earlier post by Amos)

awesome link alien!

Thanks, everyone for the replies. It seems like the issue is only on osc 1. I have not individually tested all 3 but it seems like they are not staying in tune with each other either. I am bringing it to a tech named Gerry Dahl here in Minneapolis tonight. He’s been servicing analog synths for 30+ years, so I’m praying that he can get it sorted out. In the meantime, my friend has loaned me his Yamaha CS5. Not the same thing, but I’m having a blast with it nonetheless.
