I use several sets of software sample libraries that I use in Kontakt 3 (and 2) as a soft synth plug-in within Sonar 7. I have a Sweetwater Creation Station Plus with 3 GB of RAM, which should handle it, but I may end up with a Muse receptor to handle the heavy load. However I'm having latency problems with my Kontakt instruments when I play them in Sonar. I really don't understand the buffer settings in Sonar and how they relate to latency in Kontakt. The 2 buffer adjustments I know of are (1) Under Audio Options in Sonar or (2) In the Control Panel under Edirol FA-66 Driver Settings where you can either adjust the buffer settings or check the box "Use Maximum Buffer Settings". I know its preferable to raise the buffer size when mixing and to keep it low when recording in Midi, so I don't know when you would ever check that box and raise the Buffer settings to Maximum. Does raising the buffer size reduce latency in Kontakt? How do I know how to adjust the buffer size in both of these locations in my computer? Is there any latency adjustment inside of Kontakt? What does the Buffer in Playback Queue mean (in Audio Options) Thank you for any help you can give me.

Hi Don,

If you're using WDM drivers, use the Buffer Size slider in the Audio Options dialog box to adjust latency.

If you're using ASIO drivers, use the FA-66 panel that pops up when you press the ASIO button.

The more soft synths you use, the higher you will have to set your latency. Unfortunately, there is no standard setting. You will have to test out different settings to find the right one for that particular project.

However, if you are done recording your MIDI tracks, you can raise the latency quite a bit to take a lot of the load off of the CPU.

Hi Don,
raising the latency buffer in your FA-66 to maximum will INCREASE latency and decrease CPU load, however only if you're in ASIO driver mode in Sonar. if you're using WDM driver mode, then the latency buffers are managed by sonar in the OPTINOS>AUDIO>GENERAL window.

using MAXIMUM will increase your latency and reduce your CPU load for mixing.

I don't think there will be a latency adjustment in Kontakt - latency is mostly controlled by the CPU, RAM, Audio card and its drivers. I don't have Kontakt, but in GS3 you can adjust how much memory it uses and how much streaming is done from the disk, but the latency itself is not directly controlled inside GS3.

so if you're using WDM driver mode, you control the latency by using the latency slider in sonar under OPTIONS>AUDIO>GENERAL. if you're using ASIO mode, then you control the latency using the buffers in the soundcard software panel. however, most of the time if you have sonar OPEN when trying to change those hardware buffers, you MUST go thru the ASIO button in that same window (OPTIONS>AUDIO>GENERAL) to open the soundcard software or the settings won't change. if sonar's not open, then you can change the hardware buffers from the software panel without a problem.

Hey Beagle - Great minds think alike, right?

Beag and Scott, Thanks so friggin' much for helping me get over these problems without having to resort to buying more hardware (the Receptor), I really appreciate it. Now I see how I can use the Kontakt samples without overloading the CPU and by understanding the settings better. I'm loyal as hell to Sonar, (I've been using it since it was Pro-Logic) but I'm a little pissed at them since I bought and paid to upgrade to Sonar 7 two months before they announced they were coming out with Sonar 8. Their policy is only 30 days for free upgrades, so, being a month late they wouldn't give me a free update. Two months! I thought that was unreasonable. So it's hard for me to complacently pay the extra money, which is why I'm sticking with O.S. #7. Think I'm being a testa durra (hard head - in Italian)?

Hey Don,

If I was running a company, I would have to put a limit as to when free upgrades were available, so I'm not sure if Cakewalk is in the wrong. But you are the customer and the customer is always right, so maybe they could have made an exception (as long as you wouldn't tell anyone else about it).

Anyway, just so you know... Cakewalk usually comes out with a new version of Sonar every year at around September. That's no guarantee that things will always be that way, but they've done it now for at least the past three or more years. So just wait till September next time and you'll be all set.

Scott
