Can still hear the note when no key is pressed

Postby cgraye » Tue Sep 25, 2012 11:22 pm

Hello, everyone. I'm completely new to the Voyager (and analog synthesis in general), so I don't know exactly how all this works yet. But I'm hearing a sound on the Voyager I did not expect.

I have the outputs going from the Voyager into a mixer, and I am monitoring the mix with headphones. When I press a key I hear a note as expected, but when I let the key go, I can still hear the note very faintly coming from the Voyager's right output, and it continues forever. If I unplug the cable from the right output, I can hear it from the left (mono) output. If I turn the oscillators off (or turn the volume all the way down) in the Voyager's mixer section, I can't hear it anymore. And if I plug the headphones in the Voyager's headphones jack, I don't hear it either.

Is this expected or is it some kind of problem?

Thanks for any help.

How loud is it? How is the gain and volume set on your mixer?

The calibration of the final VCA could be a little off. Just a bit too much initial gain. Don't know how you can adjust it though. There is no service info available.

That's a problem. Sounds like something is wonky with the VCA on the right output. Call tech support.

Thanks for the responses. I called tech support and wound up sending them an audio sample, so I'll see what they have to say about it.

Working with analog gear this way is really a huge change. I'm never sure whether something is off or I'm just getting getting variation within expected tolerances.

Well, tech support tells me it is within expected tolerance. But no one else has ever heard something like this?

Mine does the same thing, only when volume is set quite high

Yes, some bleed through is to be expected with analog VCA. But like Kenneth said, you have to amplify the signal hundreds of times in order to hear it usually.
I have the same thing on my Minimoog D, but in order to hear it, I have to raise the volume on my mixer so high, that if I were to hit a note accidentally I would probably go deaf ! :lol:

But at normal levels, you shouldn't hear much of anything once the Volume Envelope release has ended.

Maybe you could make your audio sample accessible for us to hear it ?

Hi there!

I have the same noise and recorded it with a video asmple here. Is it the same on your voyager??

I can hear the noise even when the Master volume is completely down.

Kind regards!
Sorry for my bad english!

Yes, that seems to be the exact same thing I am experiencing.

Here is a clip of mine. Listen through headphones and turn the volume up.

yes it is! And it´s very hard to record this tone! But you can hear it quite good on the speakers... And I still think this is not normal, because why should people on stage hear this tone (master output) and youself through the headphones not. I din´t try it out yet on a big Soundsystem but when it behaves the same like on studio monitors then it´s strange i think.... more confused :roll:
