ES-6 noise(?) problem

Author ES-6 noise(?) problem

Hi.

I have problem which I am not sure it's problem with ES-6.

I have 2 ES-6 and both have same issue.

Please see the picture I inserted. They are the screenshots of ableton live I/O. I didn't plug anything into ES-6 and I got those noise(?) or offset from it. The pictures are the 2 of my ES-6. I measured voltage and wrote it under the track's fader. I did only one of 2.. It's a bit different. One is a bit better than the other.

Can I use them like that?

Big Thanks

Those are most likely DC offsets, which are expected.

Live has a DC blocker in its Utility device. Does that remove them?

Is there any way to remove them? I'd like to record CV data from modules and playback to modules.
Since 2 ES-6 have different offset each other, I have to stick to one to recall correctly.

Then, I can't record CV data( they are sometimes static like DC), can I?
os
If you need to remove them, you would do it in software e.g. you could use SW Function (part of Silent Way).

Do you actually need to remove them though? If you 'monitor' your CV through the ES-6 then the offset is taken into account in what you hear anyway. The effect of the recording would be the same as the live CV, even with the offset.

Is the offset always there with the same amount? Then I can live with that. I did't test it yet.

One more thing....since 2 ES-6 have different offset each other, I have to stick to one to recall correctly or I have to store which one I used....

So are those offsets normal and nothing wrong with the device?
os
Yes it's normal.
gummyboy
I tried to get CV signal into max.
They all came in very different voltage level. Some are twice different each other...

1. Is this still normal? For me...it's a bit weird..
This means if I have some setup, I have to maintain the path(which input I used for ES-6) to get the same result.

2. Those offset remains the same value? If so, that's a bit better though...



In this img it only has first 3 inputs of ES-6.
e.g. input 6 of ES-6 has exact 0 volt in if nothing patched into.

The offsets will be different, but the amplitudes should be roughly the same. Can we see an oscilloscope view (or just a WAV recording)?
gummyboy
Do you mean WAV recordings of LFO fed into each inputs?

I don't have oscilloscope in the computer. Only have Mordax data.

Yes.

There are free oscilloscope plug-ins available.

You can see the amp difference between inputs. I buff multed LFO and into ES-6.

And here is the live project file of wave recording.

Thanks. That's not right. You'll notice the waveform on input 2 isn't the right shape, either.

It's a hardware fix, unfortunately. Email me if you want to send it here.
