Moog Voyager out of Tune

[Jankele]

hello everybody,

the oscillator 1 of my voyager is a little bit out of tune proportionaly to osc 2 and 3.
even after i play on the voyager for more than an hour.
is this a purpose or some kind of a defect in the tuning device of my voyager?

best,

jakob

The pitch of osc 1 (and the relative pitches of 2 and 3) is set by the fine tune knob. It is on the far left under the LFO.

The way you tune the voyager is as follows:

*Warm up the Voyager (turn on for approx 10 mins, play some sounds).
*Switch off osc 2 and 3.
*Set osc 1 to a sine
*tune to an external source (sine if possible - will enable you to hear "beating")
*turn on one of the other osc and tune it to osc 1.
*do the same for the other one.

Be wary that as it is an analogue instrument, very small changes in its tuning can result over a period of time - but for an instrument working well, this is hardly anything. Also, you will have trouble getting all oscs entirely in tune with each other - but a good patch frequently has some small degree of difference in the tuning between oscs.

Are you talking tuning or scaling? If it is in tune at one note but they go out of tune with each other a few octaves apart, that is scaling. That will need calibration.
