Good evening all,

I have recently purchased a Studio 1824 USB AI. I have everything working, but I'm having issues with the Blue Z workflow.

When I have my settings a certain way in the Studio One preferences, Blue Z mode becomes available. I have a cue mix setup so that the second headphone out is mirroring Out 3/4. I go over to my mixer view, engage Blue Z on the phones output, turn on the monitoring for the drum tracks coming in from the Pearl Mimic Pro, and put my headphones on.

I am definitely hearing latency. I am quite sensitive to it. It feels like I'm playing a sponge compared to when I play the drums with the phones connected directly to the module. It's not subtle. Feels like 11+ ms to me.

So - what do I need to do to get this to work the way it's supposed to?

Also - the headphones out is really weak on here. I donm't get much gain coming off the phones output, even with the knob turn full open. The same phones on the drum module itself at about 75% are way louder and more "transparent". It's almost like I'm listening to the old unit with the -10/+4 switch backwards and getting low level output from the phones.

These are two things that are bothering me. The purpose of getting the Presonus unit was to have the full integration with Studio One, to be able to use the headphones, and to use the Blue Z basically NO latency version of the recording workflow without having to switch a bunch of stuff around whenever I want to change what I'm recording.

My current workaround for this is to send the mix from Studio One to the Out 3/4, which I have sent to the Aux Input on the Mimic itself, where I can monitor the sound coming from the DAW on that Aix input and monitor the drums directly from the phones out on the Mimic. But this is how I had to do it on my old AI, so I would really like to resolve the Blue Z and the phones Output level if possible.

Looking for any assistance on getting this working. Even if I have to keep the routing for the drums working this way, I'd like to be able to use the Blue Z for vocals at least.

So... Am I the only one who is having issues such as this?

The 1824 is fairly new so there might not be too many people with them.

You might want to do two things

1) show is picture of you audio processing page with the drop ou protection info on it and blue z numbers.

2) ask th question in the 192 forum which will have more people who can do Blue Z.

Blue Z should be direct hardware monitoring so if you're hearing latency you're not monitoring hardware direct or you're listening to a different signal path. If I correctly understand how hardware direct monitoring works, It's input AD->DA output directly, which should only involve converter round trip latency which is near zero.

Outside of user error, the only other explanation would be something wrong with the driver build or something where it's just simply not working correctly.

Hey supt4, I am open to it being user error with my newness to studio one and the interface, but everything I have read and seen says to turn the option to allow hardware direct monitoring In the options, then engage the blue z on the output you want to MOnitor through. There doesn't really seem to be anything I could muck up.

But I very clearly hear latency. I will give it another shot and see if I was just having a bad cognition day or something. Then I will TRY to capture a video showing the problem, which might be hard for me since I will be trying to getting routing set in a way that will show a routing problem using the very interface on which I am having it... :geek:

Please see this video:
https://www.pro-tools-expert.com/studio-one//studio-one-low-latency-monitoring-blue-z-vs-green-z

I own the Studio 192 mobile interface. Maybe I'm wrong, but the blue z workflow is used together with interfaces which have a built in DSP hardware chip. So, I'm not sure if you can use the 1824 AI with zero blue z monitoring.

Another good explanation how to use the blue z and the Fat Channel integration in S1:

I saw both of those videos and watched several times. As I understood, if the blue z option were not available e at the driver level, the blue z wouldn't be shown as an option.

Interestingly, the blue z shows up as a choice in various different settings of latency in the two settings tabs but with other settings, the checkboxbfir hardware latency goes greed out.

I am still not convinced that it isn't a driver issue.

Hi Blades,

I didn't mean "user error" quite that literally, no offense was intended there so apology if you took it that way. Was more suggesting that even when using directly hardware monitoring it's still possible via other separate signal routing to inject a latent mult of that same signal into the monitor path.

You are correct (afaik, your earlier observation) that if you can turn on the blue Z that means that your audio device supports direct hardware monitoring.

Also, it is normal for it to be grayed out under certain buffer and protection settings.

Let focus on you exact monitoring path.
My theory is you are hearing a double signal.

1) normal but please start showing all details with pictures See details at end of post for tools.viewtopic.php?f=151&t=17142

3) We will need to see your routing. This can be done with videos, or by creating pictures of the flow ( even drawn with a pencil)

4) this is why I think we have a misguided signal path

5) this is called out of the box monitoring so let not go there yet.

Hey folks. Thanks for the input so far.

I'm not offended by suggesting it is user error on my part. I've been around the DAW usage for along time,. but I'm very new to Studio One and to this interface, so I could be missing something for sure.

Here is the basic physical signal path:

Pearl Mimic Pro -> Behringer ADA8200 -> Studio 1824 (via ADAT) - though I also have a few channels going straight to the analog inputs on the Studio 1824 for the hi-hats and ride, so it's not that the ada8200 is introducing some problem.

In Studio One, under Song Setup...Output, I have Main Out set to Line Out 1 and 2
I have (what I've named) Headphones set to Line Out 3/4 and have Cue Mix selected (and in the Universal Control I have the headphones 2 out set to mirror 3/4)
In the S1 options, I have the Audio device set to 64 Samples (44.1/32) and showing 2.95/2.49ms latency
In the same options under Processing, I have Dropout protection set to (whatever) and the checkbox for "use native low latency moniroting instead of hardware monitoring" UN-CHECKED

With all of this, I set one channel to Input Monitor on the S1 mixer, I click the Z under the Headphones Cuemix, and I hit the snare. I hear the latency.

I have found that as I change the Dropout Protection to different settings, the latency increases accordingly, as if I were using the "low latency monitoring" instead of hardware monitoring. In fact, if I change that checkbox and get the Green Z, there is no difference in the latency result. The reported roundtrip latency is what I'm hearing in Blue Z or Green Z mode.

So - from that much info, are you able to tell anything?
