so i upgraded my voyager signature from version something (old enough not to have a version number in the software) - likely original from the factory to the 3.x board. i followed the instructions, checked the voltages on the oscillator pitch, and got the variance between low and high to something like ± .03V, which seems pretty close.. at the same time, i decided to tune up my unit to fix some tuning issues i had noticed - mostly that the second oscillator was not in tune with the first, and my tuning knob was constantly at 11 o’clock, so i figured hey, this should fix it.. it fixed my osc sync problems, but now i’ve got some other interesting things, and i don’t know if these are normal, or if i’ve buggered it with my tuning process (followed the text sent to me by Ryan):
-
if i change the pitch bend range in the DOWN direction, there is no change to the pitch of the basic, non-pitch bent tone.. however, if i scroll up through the ranges in the UP direction, it moves the tuning of the basic tone sharp from on pitch at OFF to over a semitone sharp at 2 octaves.. this is just adjusting the range, not actually laying a finger on the pitch bend wheel..
-
when i do lay a finger on the pitch bend wheel, the down bend is sharp linearly across the ranges, so for a fourth, it’s only a bit sharp, but on 2 octaves, it’s over a semitone, so bending C5 2 octaves down gets me to a little north of C#3, same in reverse..
-
the oscillator tuning knobs don’t get me as far as the silkscreen would lead me to believe - i.e. at +6.5 or so i hit a fifth, and past +7 gets me to a fifth plus a semitone..
I don’t know enough about this synth yet to know if these are normal, definitely bad results, something i can fix by re-doing the tuning procedure, maybe this time not forgetting something (if that’s what i did), or if it’s bad enough it needs a trip home..
thanks!
