I recently sent an email to tech support (about a week ago) but haven't heard a reply back yet so I figured I'd post my message here in case it wasn't received (I used the Moog website form to send the message).
Here's my message:
I have done an oscillator tune (using a good quality strobe tuner) since sending this email according to the following information I found but I'd still like to know the official Moog method (I found a number of methods using Google but not sure which one is the 'official' one).Dear Tech Support,
I have just recently purchased a Voyager EB edition and am absolutely delighted with it. I'm a sound engineer and musician (my gear list and music is available freely on my website at the end of this message) from Australia and am also a qualified electronics tech with three decades of experience in design, construction and customisation of synth and studio equipment.
I have a private recording studio and a collection of analog and digital synths which I've collected over the years, many of which I have done extensive modifications to. Amongst that collection are various analog synths/sequencers which I am designing a modular i/o panel for. Now that I have a Voyager, I am hoping to integrate its CV/Gate i/o capability into my custom panel design. This panel will also have additional i/o for my Roland System 700 sequencer, System 100 synth (complete with all modules), SH09 which I've modded with CV i/o for all sections, Juno 6 with extra i/o, Juno 106 which I am modding for extensive CV/Gate i/o and JX3P/PG200.
I found the Voyager 25 pin expansion port pinout via a Google search and have also discovered the necessity of installing a small PCB in the Voyager which I've read contains some 330 ohm resistors to prevent oscillation when a cable is attached to the expansion port.
Would it be possible to obtain that PCB and some additional information (schematics possibly) regarding the VX351? If I wasn't building my modular panel for the entire synth rig, I'd just purchase a VX351 but it would be somewhat redundant considering my project plans.
Also, I am planning to do a full oscillator tuneup and am wondering if you'd be able to provide the procedure to do so? I have read a few different procedures on various forums but would like to use the official Moog method. I have frequency counters/oscilloscopes/tuners in my electronics lab.
Looking forward to hearing back from you.
Keep up the legendary work!
Kind regards,
David.

The method I used:
Power on and let warm up for 1/2 hour.
Before each oscillator adjustment, I loaded the init voice patch (which I previously copied, disabled the pitch bend range and saved as a new init preset).
Osc 1
1* Play low E (on 8' range) and adjust RT2 (range)
2* Set oct to 2' and adjust RT1 (scale)
3* Repeat 1 & 2 as necessary
4* Adjust RP11 (Low E) on 1' octave
5* Set oct back to 8'
6* Play high E and adjust RP9 (KB Track)
7* Repeat 1 - 6 as necessary
Osc 2
1* Play low E (on 8' range) and adjust RT4 (range)
2* Set oct to 2' and adjust RT3 (scale)
3* Repeat 1 & 2 as necessary
4* Adjust RP20 (Low E) on 1' octave
5* Set oct back to 8'
6* Play high E and adjust RP21 (KB Track)
7* Repeat 1 - 6 as necessary
Osc 3
1* Play low E (on 8' range) and adjust RT6 (range)
2* Set oct to 2' and adjust RT5 (scale)
3* Repeat 1 & 2 as necessary
4* Adjust RP14 (Low E) on 1' octave
5* Set oct back to 8'
6* Play high E and adjust RP16 (KB Track)
7* Repeat 1 - 6 as necessary
* Repeat whole procedure as needed
* Close panel and leave for 15 minutes
* Check tuning and adjust again as needed.
After completing this, my Voyager is FAR more in tune (oscillator 2 was WAY out of tune before this and the other two were close but not spot on).
