Clicks occuring with DI recording

I recently started to use the QC for typical DI recordings in the studio (instead of a Kemper).

This is what I thought would be a good setup: Monitoring the actual sound through Out 3/4 and using Send 1 for output of the DI signal. Everything is connected with symmetric cabling, guitar is connected to In 1.

However, once I use In 1 in two lanes at the same time as shown above, I get clicks in my recorded DI track. The 2nd pic just shows me thumbing on the muted strings, the clicks only occur if an actual signal is coming in from the guitar.
Is this a known issue? Am I forced to split the signal right after In 1 in the top lane to avoid this?

Update: This routing setup, splitting the signal right after the input to output DI on Send 1, produces the same clicks. Now comes the weird thing: If I deactivate the monitoring output Out 3/4 on lane 3, the clicks on Send 1 are gone.

This seems to be a major problem - DI recording is impossible with the QC right now. :frowning:

are you unable to use the QC as interface in the studio? Connecting via USB would eliminate all these issues as you get an automatic DI from channel 1 with no manual routing necessary. If there’s a Mac available, you wouldn’t necessarily have to swap it out for the interface- you could merge the QC and create an aggregate device.

I suspect the issue you’re seeing is not with the QC but rather the computer or DAW, though I’m not positive why it is causing that. Curious to see what other users think

It’s definitely not the computer, as this issue only occurs with the QC in this certain setup and as shown, I don’t get clicks if I deactivate the 2nd output or 2nd input. I also changed the cables and tried different guitars. Without incoming signal (= no guitar connected) clicks don’t occur.

I do record several other analog sources without a problem.

In the end it’s just a simple analog audio connection, so clock or sample rate issues are out of question.

Using USB is not an option as I have everything connected to an RME Fireface as the main I/O hub, and Cubase on PC doesn’t allow multiple interfaces to be used at the same time.

Yeah, sample rate and buffer size are the usual culprits for this, but if you’ve ruled that out then it’s a bit of a mystery.

Have you contacted support@neuraldsp.com yet?

No, not yet - I was hoping for another user with that problem solved already.

But then it looks like I’ll be going that route. Thanks anyway! :slight_smile:

Are you connected to the Internet while recording if so don’t be, turn off Bluetooth and turn off windows security and see if that helps while your not connected to the Web…. Also the wdm drivers should match up windows oufio needs to be the same sample rates and same audio device… that’s what those pops and spikes look like

It’s not a Windows or DAW issue.

I’m recording an analog signal. I don’t have any problems recording any other sources. I’m literally hearing these clicks from the QC even if I’m not recording.

Have you tried putting the send at the start of your preset… 1st block that’s were I usually put my sends when playing live or when in the studio the guys usually want a clean send from me

Yes, it doesn’t make a difference.

I will be down in studio later I’ll do a test and see if I come across any issues like that and get back

No probs hope you get sorted quickly :+1:

So it seems like this was an issue related to the distinct preset I was using.
Starting a preset from scratch using the double In1 and separate outputs identical to the faulty preset I posted did not produce any clicks anymore.
This might have been caused by the fact that that preset was created on another QC initially and imported via system restore. Or it might not. :slight_smile:
