hey all,
so i set out on an experiment to map the pitch intervals on my voyager’s oscillator section. i’m not sure if anyone will really care about this, but here-goes…
TESTING:
-
fired up a softsynth VST that uses standard saw waves
(note: sine would have been preferred but the voyager doesn’t have sine output) -
matched the waveform (as close as possible). then tuned OSC1 (with the fine tune knob) and the softsynth to unison. also i made sure OSC2 and OSC3 were tuned to OSC1.
-
used the softsynth to play half-steps up and down the keyboard
-
leaving the voyage on the root note, disabled OSC1 and tuned OSC2 to match the notes played by the softsynth
-
compared the voyager harmony with the same interval in the softsynth back and forth
-
retested later and tried both OSC2 & OSC3 interchangeably.
RESULTS:
tuning direction: DOWN
0 = C (root)
- 19 = B
- 36 = Bb
- 54 = A
- 72 = Ab
- 89 = G
-106 = Gb
-124 = F
tuning direction: UP
0 = C (root)
- 16 = C#
- 33 = C#
- 51 = D
- 68 = D#
- 86 = E
+103 = F
+121 = F#
OSC2 offset = 0 (actual values above)
OSC3 offset = +1 (add 1 to values above)
RESULTS:
something i noticed is OSC2 & 3 share the same tuning values if you take the offset into account. for example, -89 and -88 on both OSC2 & 3 yield a G. i was kind of expecting to have totally different values for both oscillators so i think that is kind of cool. also i went back after leaving the voyager on for a while and the tuning was still accurate.
like i said, i’m sure everyone’s voyager will be slightly different. also due to the nature of analog circuitry, i’m sure my own values will drift over time. however, i was surprised how accurate the voyager’s oscillators track!!
just my observations…
