Recording problem

After recorded a small guitar part, I realized that there were some a strange noise starting at 0:30 and finishing after some seconds.
The noise was lying over my guitar sound.
You can hear it starting from 0:30 in the MP3 file (in the ZIP File).
What did I wrong?

Re: Recording problem

It sounds like some sort of digital feedback, Stefan. Do you have the scene you were using? If so, post it so we can check it for you.

Re: Recording problem

Were you recording channels 11 and 12, Stefan? How was your guitar connected to the XR18?
What software did you use for the recording?
Were you playing back channels 3-10 and 13-16 at the same time?

Re: Recording problem

I recorded channel 11 and 12 on my PC, Windows 10.
No other channel was recorded.
The guitar was connected via XLR from my Kemper.
The software for recording is Cubase by Steinberg.
During recording channels 11 + 12, there was no playing back of the other channels.

Re: Recording problem

I cannot see anything in your XR18 configuration that is likely to cause strange noises. When recording from the Analog signal tap you are only passing through the XR18's A/D converters anyway.

I wonder if it could be an interaction between sampling artifacts from the Kemper and those from the XR18's A/D? You could try changing the sample rate of one unit to see if the problem gets better or worse...

Re: Recording problem

How could the sample rate of the Kemper have influence?
There‘s only an analog signal (via XLR) coming from Kemper!

It may not. If I was experiencing the problem I would try to eliminate each possible cause in turn. Do you get the unwanted noise when you connect your guitar directly to the XR18 without going through the Kemper?

The analogue signal comes from a digital processor so will carry some digital noise components - usually at a low level. It is possible for these to create audible alias components when re-sampled by the XR18's A/D.
