A. So, what about trying to uninstall Yamaha driver?

So you use the VSTi inside reaper (not stand-alone) and have a master keyboard connected via USB?
In this setup you have about half of "RTL", as I mentioned. Only the output latency.

To put an example. UFX III, ADI-2 Pro via SPDIF for monitoring.
DAW Cubase Pro 13.0, VSTi being used for HALion Sonic.
Arturia Minilab is the Master Keyboard connected through USB to the computer.

For the UFX III, the output latency at 44.1 kHz is:
2.968 ms with 64 samples ASIO buffer size
4.150 ms with 128 samples ASIO buffer size
7.052 ms with 256 samples ASIO buffer size
12.857 ms with 512 samples ASIO buffer size
24.467 ms with 1024 sample ASIO buffer size

I could comfortably play using ASIO buffer sizes up to 256 samples, 512 was also "ok".

I took a little test in Cubase recording 1 piano note repeatedly with different ASIO buffer sizes from 32 to 2048 samples.
Below, a screenshot of the different tracks with the wave form after performing render in place.
I did my best to be in sync with the drummer.

For me, it appeared as if it is pretty safe to play with ASIO buffer sizes of 32 up to 256, maybe even 512 samples.
Playable was up to 1024, uncomfortably it became with 2048 samples buffer size.

Therefore, I would like to come back to my point.
Do you have a "real problem" playing with an ASIO buffer size of 128?
From what I see here, playing with 128 samples ASIO buffer size should be possible without any issues.
Even 256 could be possible as you do not have the full RTL (round trip latency).

Here the single wave files if you want to download and compare or play multiple together to check how narrow the single notes are between 32 and 512 samples ASIO buffersize:

Via MIDI is also fine.

Then you need maybe really a different machine with a more performant CPU, good drivers and with significantly lower DPC Latencies.

Still, you could try, whether changing USB ports improve the situation.

I think you should try different USB ports to look whether it changes the situation.

Furthermore, a good idea would be to buy a Thunderbolt docking station from Dell to isolate the Babyface Pro
behind the USB3 controller of the TB dock. Do not connect any other device. Possibly, this works better.
As thunderbolt is "external PCIe" it's nearly the same as if you would insert a USB3 PCIe card into a desktop PC.
No guarantee that it fixes anything, but would be a good chance that things become a little better, if the BBF Pro
is connected to a USB3 controller of its own, where no other USB device is connected to.

Windows 11 gives me the Windows 8 vibes of full bore GUI annoyances from what I've seen, though some colleagues says that the GUI has improved over the three years since Windows 11 was released. At my company we've managed to avoid every second release of Windows that we support for our customers, so perhaps we can skip to Windows 12 to keep the trend since Windows XP. Not any guarantee that Windows 12 is any better, GUI wise, than Windows 11.

For my PC at home, Windows 10 Pro works just fine for my purposes, I'll have build a new one next autumn unless Microsoft extends the EOL deadline for Windows 10. The EOL has been changed for other versions before so perhaps Microsoft does it again, especially as of June 63% of Windows PC's runs Windows 10 with about 13% running Windows 11.

Obviously ramses has a problem with W11.

Well, other than the recent change from buffer of 64 to 128, I also find no performance change when using my system every day. So it’s fine by me.

Buffer 64 also worked well in Windows 11 till, if I remember well, sometime after the installation of the Yamaha dSteinburg driver.

Well, Apple has been asking users to use their devices with an Apple ID for many years. It's the case with my iPhone. I haven't used a Mac, but I bet it's a similar situation. So, it's alright. I've gotten used to it.

OK, I agree to disagree. I just want to say that I don't have anything to hide from the authorities except things that needs to be hidden, let's just end that subthread at that.

Regarding my system, it looks like I'll just work with buffer size of 128 and watch my laptop slowly retire. I'll post here again when that day comes and I'm in the market for a new PC again. I see you can give me good advice in that department. Until then, take care thank you for everything, and happy music-making!

I'm not American. I'm a Chinese studying abroad in the US. In China, I know that the Internet is a public place, that information is not purely personal, and that people know what I say. That's why I said that since I've already been sharing a lot online, I don't care if big tech companies wants more info from me. I'm willing to share what I know can be shared. Also, for accessibility reasons, I prefer keeping my systems up-to-date, because certain bugs might be fixed OS wide for me so I can use the OS better with NVDA or Jaws.

So, we come from different vantage points. That's how I understand this topic.

@ramses The OP wrote that "I'm a Chinese studying abroad in the US." and China is a brutal oppressive dictatorship keeping tabs on Chinese living abroad, so obviously he/she has to be very careful what they express online.

I think this is off-topic, though.

Yes, I was downplaying it because I didn't believe it's something I need to think about at the moment, but no, I wasn't being inconsiderate to you, I was trying to quickly wrap it up and avoiding a long thread. If I sounded that to you, then I'm sorry for it and for what I said.
But I'm glad we had this conversation, to have compared notes so I knew where you're coming from. I guess what I can conclude from this was something I said above, that we are being effected by decisions, and that maybe what isn't bothering me now might worry me in the future. So, mutual understanding? At least I feel like I'm beginning to understand you a bit.

Hi everyone.

Today I was adjusting my Repaer midi device settings as I just returned to the States, and I found some legacy devices I used back in China that are no longer available. I removed them, and now the only midi devices are my Korg Nanokontrol Slider Knob, and the Babyface Pro FS Midi Port (connecting the Kawai VPC1).

And amazingly, when I put through some midi files with many notes and pedal down, it's no longer clipping and popping at 64 buffer size. Earlier I could only achieve real glitch free at 128, but now it sounds like 64 samples is working again.

This positive improvement makes me wonder -- was the unavailable midi devices the real cause behind all this stuff I've been working with over the past few weeks? If they even make a difference, then that's a very interesting discovery.

Happy weekend!
