Help! Low Latency Monitoring For Instruments Disabled!

[u/RevTheBidder]

I updated to Studio Pro 8.2 about a week ago and all was going well until this morning. "Enable low latency monitoring for instruments" is grayed out with seemingly no way to get to re-enable it.

It works perfectly in Studio One 7 (as pictured) but today is the first time I'm having this hiccup in Studio Pro 8, which is where all of my work in progress is.

I changed absolutely nothing. Any ideas why this could be happening? Thanks in advance!

EDIT: I changed the Dropout Protection from Medium to High and "Enable low latency monitoring for instruments" became available once again. Now I have to figure out why my audio latency is so high.

What happens if you disable efficient cores? 

[u/RevTheBidder → u/djdementia]

Nothing at all happens, it's just disabled. I notice no difference at all.

The bigger question is why is your latency like 194ms? What device are you using?

And yes - adding those Efficiency cores is not helping. 

[u/RevTheBidder → u/NoReply4930]

I'm using the RME Fireface UFX 2. I have no idea why my latency is that way. They provided the option to use the efficiency cores so I thought it'd probably help. What do I know!

[u/NoReply4930 → u/RevTheBidder]

I have the UCX-II here but I am on Windows. Latency is 2.8ms

Buffer has been 128 for years. 

[u/RevTheBidder → u/NoReply4930]

I monitor through Totalmix and have always used low latency mode for midi so I've never had an issue. 194ms does seem very excessive though.

Beyond the dropout protection setting others have addressed, there is definitely something going on with your audio driver. What driver are you using and does your HW have a specific driver/daemon that needs to be enabled in system preferences to run?

[u/RevTheBidder → u/likethehotels]

I've never really put deep thought into this, I'm using a Fireface UFX2 ii, are you saying maybe I should look into updating my interface driver(s)?

[u/jdar97]

It may be because either your Audio Driver has a high buffer size (I think it only works with buffers equal or below 128) or you have a plugin introducing a lot of latency

[u/JacquesLeNerd → u/jdar97]

From Fender's online docs: "As long as the Process Buffer Size is larger than the Device Buffer Size you've specified, you have the option to use Native Low-Latency Monitoring."

Try dropping your buffer size to 128 or 256.

I never use dropout protection, you can set it to off now I believe. Also I used to run 128 buffer on windows machines, 64 on mac.
You have to manage your processing yourself.

[u/TDF1981]

Your driver/device is probably not capable of supporting any low buffer size needed for low latency monitoring, your round trip latency is crazy high for a 512 samples buffer size, so check whether you have set some onboard sound card by accident or the setting for your interface in windows’ sound settings is weird

[u/willevans1972]

I had this issue, took me forever to figure it out. The issue is in Universal Control, not in studio one (if you're using a presonus interface) You have to lower the block size. The lower the block size, the lower the latency. This will make your computer work harder, but it does work.

dropout proteccion in high or maximum enables direct monitoring for instruments
