Hello! I’m wondering if anyone out there has had this problem or might help me solve it..
Basically, the pitch of my Voyager’s oscillator 1 doesn’t track the keyboard (or incoming midi) correctly anymore. When I play a ‘C’ note, each octave higher it gets a little sharper, until by C4 it’s at least whole tone out of tune I’ve tested with the other oscillators and they still track perfectly.
Anyone know if there’s a fix for this? maybe an internal pot I can adjust while looking at a spectrum analyser? I’d rather not have to send it off somewhere and pay £££ for what could be a simple-ish solution!
Anyway, any suggestions would be gratefully received,
The stretch tuning (scaling) of Osc #1 has become misadjusted.
The procedure to recalibrate the Voyager’s oscillators is rather involved, and time consuming. Also, the trimpots involved are extremely sensitive, and interactive. You need a musical instrument tuner, or frequency meter (not a spectrum analyzer) in order to calibrated it properly.
Work best left to professionals (that will offer a warranty on their work). But if you want to risk trying to recalibrate it yourself (out of warranty of course), here’s a link to the described procedure:
