Voyager pitch cv not scaling correctly.

Post by n2design » Sat Jan 12, 2013 8:19 pm

I am trying to control the voyager with an analog 4 cv out but my settings arent working right. Anyone have any idea why?

Here are my settings
Type = Pitch V/oct
Middle C = 3.00v
V/OCT = 1.00v

Shouldn't you set your A4 V/OCT to 0.93V or whatever the Voyager expects from the A4?

.93 doesn't work well either. Note is not pitched and each octave isn't 12semitones.

I didn't mean literally set the value to 0.93V. What I meant to say was you might have to use your ear to determine the proper setting. It could be 0.94V. Or 0.92V. Or 0.9378V.

start by setting the first c / 0volt.
when that is tuned well, take c1 and adapt the midi/cv or controller signal so that c1 is tuned.
don't start on c3...

The Voyager output CV without CP-251 is 0.93V/oct.

The Voyager CV input is 1V/oct.

The Voyager CV input is 1V/oct.

That's strange, Why did they make them different?

btw, turns out the a4 scaled correctly via cv @ 1.02v

Looks like a CP-251 is a "must-have" if I ever want to play an external oscillator (eg. Make Noise DPO, Malekko Anti-Oscillator, etc.) in-tune from the Voyager keyboard.

Congrats n2design on solving your issue
