Over the last few days I’ve noticed that my Voyager has seemed very out of tune. I was considering sending it in for a calibration and started playing around with it tonight before boxing it up so I can ship it. I noticed a strange thing…
My Voyager starts out perfectly in tune. Using the pitch bend causes it to go out of tune. It appears that when the pitch bend wheel returns to center all the notes still play as if the pitch bender is still being used. I’m curious to know if anyone else has ever experienced this.
You can adjust the pitch wheel center position yourself.
You had to do so when upgrading from OS version 2.0 to 2.1.
Here is the description of this taken from the OS 2.1 update manual:
Pitch Bend Zero Adjust
A change has been made to the scanning of the controls, which may result in an offset in your Pitch Bend Zero value. This means you may hear a change in pitch as the Pitch Bend Amount is increased. There is a simple solution to fix this. It requires an adjustment to a trimmer under the Left Hand Controller (referred to below as LHC). This will not void your warranty AS LONG AS YOU FOLLOW THIS PROCEDURE. It requires only a #2 phillips head and a small (1/8”) flat head screwdriver.
Go to Master Mode and choose “Software Version” press ENTER. Press the CURSOR switch. You will see a display showing the Voltages from the Wheels.
Note the Value for the Pitch Bend Wheel. Normally it reads Zero – after installing Version 2.1 – this may read 0 to +5. If this value is Zero you do not need to make any adjustments. If it is greater than Zero, proceed.
Remove the two screws on the front plate of the LHC. Place them some place safe.
Remove the Wood Spacer that is under the front of the LHC. Place it with the two screws you removed.
CAREFULLY lift the front of the LHC, pulling slowly away from the Voyager. The corners may be sharp – so be careful not to drop it…Note that the back of the LHC panel rests on a shelf at the back of the LHC cavity. Don’t make any sudden “jerking” movements that would pull on the cabling – the LHC is attached to the cabling going to the main chassis, and the keyboard.
You will see a circuit board underneath with three small Trimmers (potentiometers). They are labeled “PITCH”, “ZERO”, and “MOD”. DO NOT TOUCH THE ZERO or MOD TRIMMERS OR OTHER PARTS INSIDE THE LHC!!! THIS MAY VOID YOUR WARRANTY!!!
After you have located the PITCH trimmer, with your small flat head screwdriver turn the trimmer slowly counterclockwise while looking at the display. The Pitch Wheel Value should decrease. Decrease until you see –1, then, with the lightest touch, turn the trimmer a tiny bit clockwise until you see the –1 change back to Zero. > Carefully Lower the LHC back down making sure that the back of the LHC is engaged on its shelf when the LHC is at rest.
Replace the Wood Spacer and thread the screws back in. Ensure that the LHC chassis is as close to the side of the Voyager as possible before fully tightening the two screws.
That’s it! If you experience any problems or have questions before trying this, contact > techsupport@moogmusic.com> ."
If you are a bit experienced with opened synths, try this. If not, let it adjust when you calibrate your Voyager by a tech.[/quote]
