A funny thing happened on the way to ASIO #2922397 12/12/19 09:31 PM

Earlier tonight my piano suddenly felt like rubber. Disconnected.
The latency must have been somehow way higher than normal. Why?

I opened Kontakt's audio control panel and I saw this:

[Linked Image]

512 buffer with 12.5 msec latency. No wonder the keys felt like rubber.
So I clicked "ASIO Config" and I saw this:

That's looked wrong. There were no controls to set the buffer size. The controls used to be there, but they were gone. Why?
(Also ... why did they rename this "Universal Control". Is Presonus taking control of me or of my piano? Do they think that "all your piano are belong to us?")

A quick hop to Presonus.com revealed the latest driver for this Audiobox USB interface.
Downloaded. Installed just the Audiobox ASIO driver. It told me to reboot.
NO CHANGE !?

Hmmm ... Reinstall, but this time choose all the options, included newer Presonus interfaces that I don't even have. No reboot required.

I re-opened Kontakt's audio control panel and clicked "ASIO Config" again, and I saw this:

[Linked Image]

The controls had returned. The buffer was set to 512, so I changed it to 64 as pictured above.
I closed Universal Control and the Kontakt control panel then showed this:

[Linked Image]

Back to 2.5 msec latency. S'good.

So why did my buffer controls disappear?

An automatic driver/OS update, without your intervention?
(assuming your PC is connected to the internet)

All these years playing and I still consider myself a novice.

I am thinking about trying VSTs, what computer and connection setup do you have that you can run a 2.5ms latency? Is this with a large sampled piano vst (like vienna sound labs synchrony pianos) or something more easy to run like pianoteq or smaller sampled piano?

The piano software doesn't matter. The latency is almost all coming from the audio chain. That's what gets fixed when you substitute an ASIO driver for the native Windows driver.

You still need a decent computer to get 2 msec latency. But even with my fifteen-year-old POS laptop I was getting 12 msec.

Hi Mac. How do you get 2.5 Ms latency. I get 6.5ms
I have buffer 64.
Running PC with core i7 7700 with 8gb ram.
Running asio drivers

The output latency is 5ms

Is it because ur using that presonus audio interface that u could get it lower?

I'm want to get it to 2ms

I tried playing with tht hz sample rate but it make slight but little difference.

I'd love to say that I have superior skills in every way. smile
But in fact all I did was plug it in and choose the buffer size.
You can praise whoever built the interface and its software for giving me this level of performance.

I'm running an i7-7700K, which is only marginally faster than your i7-7700.
I cannot explain how your setup differs.

BTW, what interface are you using?

I think i'm a bit confused as to what creates that latency. I'm assuming it's not to do with latency from the input because no piano was plugged into USB to get those numbers.

I was using Kontakt5 installed into the PC. I just go into the settings and see what the latency is using the ASIO4all drivers and it says 6.5ms.

But i tried plugging into my Casio GP400, it plays okay....i still think the onboard is quicker and i struggle a little more on the fast passages using the VSTs. I cant say if it's because i'm not used to the sound, or if the Latency is what makes me play less cleanly.

Is there any way of checking latency in Garritan CFX? I cant seem to find any page that shows it.

The latency check is in the ASIO driver software. Sometimes the software that "hosts" the virtual piano will offer a menu link to the ASIO control panel. But ultimately it's the latter that gives you the answer.

Kontakt (or most any host) communicates with the ASIO driver, allowing the host to show you the buffer size and/or latency value.

In the end, though, the latency is in the driver.
When Kontakt tells you 6.5 msec ... can you not then click ASIO Config to open the ASIO control panel?
From the latter you can change the buffer size. Latency is directly proportional to the buffer size.

Just to give an update. U were right. The config section of asio had a buffer that added 4ms.

I'm to 2.5 which is acceptable.

Updated the frequency hz. To 96000 and it lowered even more to the range of 1. Its good now.

Thanks mac
