Platinum & NI Komplete 10 Ultimate

Komplete 9 here plus Platinum.....  sorry.

I tried Rounds today for the first time (it's the first Komplete 10 instrument i've tried, I am a new user) within Cakewalk. I was just playing a few notes on my midi keyboard auditioning the sounds and I am getting intermittent clicks and glitches in the audio. I am wondering what kind of performance others are getting. For example, how many Komplete 10 instruments can one load before running into issues.
Thanks for any feedback.

Komplete 9 Ultimate user here. I don't know about Rounds but I've had no performance problems with NI synths in general. I often have upwards of 3 or 4 instances of Monark (very CPU intensive) as well as many other Reaktor synths and effects, plus Massive, FM8, Kontakt etc. All runs smoothly without glitches but then again my system is a beast. The only problem I've faced is that occasionally, some NI plugins have lost their settings when a project loads. Mainly Reaktor and Solid Bus Comp.

You shouldn't have to up the buffer size, unless you're at 48 samples or something like that. Generally 128 should be fine unless it's a particularly heavy project. You shouldn't be getting clicks and dropouts just from one synth. What about your sample rate? I generally stick to 48kHz. Is Rounds a Reaktor based synth? If so you can change the sample rate that Reaktor works at in the Reaktor settings. Although I have to say, I often run Reaktor synths at 96kHz without problem. 
 
Have you tried the other synths in Komplete? If they're all fine then at least you have it narrowed down to Rounds. It's worth asking on the NI forums as well although they are notoriously quiet. 
 
Honestly, with the system you have and the RME Babyface, you shouldn't be having problems like that. I'm not sure how you check latency issues on a Windows 8 system because DPC Latency Checker, which is the standard, does not report correct values on Windows 8 (this freaked me out on my new Windows 8 box when I first tested it, before I knew that DPC wasn't compatible with 8). I can generally have browsers open and be downloading stuff (I backup to a cloud constantly) with no cracks and pops in my audio. The only thing I can think of is if you have WiFi enabled - that's a notorious crackle causer. 

All in all ultimate 10 is awesome , but as mentioned Rounds which is a great vsti But it's a cpu hog.. I would have to say with all my plugins rounds dose the most damage to my cpu.

Hello,
 
My first suggestion would be to see if you can use ASIO as the driver instead of WDM/KS. I would also take the NIC card one step further by disabling it in Control Panel ( even unplugged the driver is still active). You may be able to get rid of the glitch at the start by tweaking the Loop points slightly outward as long as it does not adversely affect the timing. For laughs modify the buffer to 512.  Let us know how it goes. Thanks.

Hello,
Let me clarify what I meant by tweaking. In working with some midi files, I have found that depending on where the note starts there are times when upon hitting transport I either get a glitch or click or the first not does not sound.  I addressed this by either moving the loop point to not be exactly on the start of the clip or by slightly lengthening the midi clip to I am assuming allow the first note to "hit". 
 
In regard to Rounds, did adjusting the buffer do anything?.. Disabling the nic card?

Try turning on the metronome during playback (in the options) and then muting it so you can't hear it. This is a workaround which stops the looping click in many cases. 
 
You should definitely be using the ASIO driver which came with your Babyface. RME drivers are superb and I doubt that it is causing the clicks. But there is a known issue with softsynths, looping and clicks. For some reason the metronome hack above seems to clear it up. If not, keep the metronome one and try a few buffer settings since that seems to have an effect as well - higher buffer settings may even make the problem worse (I think I recall someone else saying that in another thread).
