AISO buffer size in Cubase 14?

In discussing latency issues which I thought might have been attributed to my midi keyboard (Arturia KeyStep37) a tech support person at Sweetwater suggested that I should try altering the buffer size in Cubase14.
I can’t find any setting which refers to buffer size. I remember working in Cakewalk and Sonar and seeing a specific buffer size which I could adjust the number of samples.
I can’t find any such setting in Cubase14. I’m using the Steinberg built-in ASIO driver, which shows the shortest (but non-adjustable) input latency setting, 10ms. I would love to get that down to be 3 or 4 ms but I can’t see any way to adjust it.
If I use the Generic low-latency ASIO driver which I have on my computer (HP 17" Envy with 32GBRAM, Win11Home, using the RealTek onboard audio card with audio output running through the headphone jack to nice external speakers) that jumps to 44ms and if I try to use ASIO4ALL that setting is 17.667. And no matter how I adjust the buffer size indicator in ASIO4ALL there is no change in what shows up in Cubase14.
Is there a setting that I am missing, the old fashioned kind with a list of possible sample sizes to select for a buffer size?
Thanks in advance – I’m very new to Cubase and the manual is not clear at all on the issue of latency.
I did search this forum for the term “buffer size” and got no hits that were relevant to what I’m seeing in Cubase 14.

You are looking in the right places. Just… with the hardware that you use you won’t get anything better than 10ms. It is a hardware and OS related issue.
People who want to have a lower latency than that buy a dedicated audio interface which comes with an appropriate ASIO driver.

You’re not missing anything except that you are not going to get lower latency with a Realtek onboard chipset. That is fine for computer sounds and playing back music. YouTube etc but not for real-time audio playing. You really need an audio interface with dedicated asio drivers which I are capable of low latency.

Thank you very much – I was afraid of that.

After our discussion yesterday I remembered that I had a Behringer audio interface tucked away (hadn’t used it in a while). I downloaded the latest drivers for it and am able to use it as my audio out, and can set the buffer size. With it at 256 I get 6.33ms latency – much improved over the 10 when I use my computer’s built-in soundcard. And if I set the buffer to 128 the latency goes down to 4.something.
Now I have to experiment to see how the whole project works with the buffer that small.

Hi. I am getting an unacceptable amount of latency from my AKAI MPD 218 into Cubase AI 14. When I go into change the settings I find they are set at 10ms input and 20ms output. I would have thought this would be almost unnoticeable but it sounds like about 200ms delay. Is there anything I can do to improve this?
I’m on a PC with Windows 11 (urrg) with 16gig of RAM and I’m using the Steinberg UR22 mkII interface which obviously has dedicated drivers. Thanks

10ms/20ms sounds like standard setting of Steinberg built in audio driver and is easily noticeable though shouldn’t feel like 200ms. Are you sure you use the correct Yamaha Steinberg USB driver?

Also note that many plugin add latency if in the monitor chain…so try to remove or disable (not bypass, that does not remove the latency) plugs that come after the midi instrument so track inserts, master bus inserts, control room inserts…for a quick check if this is the issue use the constrain delay compensation button (disables plugs with latency)
