Kontakt - Weird consistent pop when using Scarbee MM-Bass

When I'm using Scarbee MM-Bass (a Kontakt instrument), I often hear pops and clicks, particularly when I'm trying different articulations. 

I recorded a short test using Sonar. During playback I hear a pop in the same place each time. Even when I render it to audio, I hear the pop in the same place!

The pop is present in both Sonar 8.5.3 and X1b, and on 2 different sound cards (one ASIO and the other WDM). Increasing the audio latency does not help.

The fact that the rendered audio contains the pop suggests that Scarbee MM-Bass itself is generating the pop, and not the sound card.

Since Scarbee MM-Bass is developed by Native Instruments, I posted these questions on their forum.  However, the Sonar forum always seems to get me more responses, even about Kontakt, so I'm posting here as well in hopes that some of you Kontakt users can offer suggestions.  Also, my project file is Sonar.

I attached my Sonar project to my second post here: http://www.native-instrum...howthread.php?p=862604 - it's called pop.zip.  It's just a simple, short bass line using Kontakt. 

In this simplified project, the pop isn't actually 100% reproducible.  Sometimes, the first long chord plays and I don't hear the pop at the marker.  Most often, however, the first long chord gets chopped off, and I hear the pop later on.  The two glitches seem to be related.

When you play the project, can you hear the pop? 

Has anyone else had this problem with MM-Bass or any other Kontakt instruments? Is there a workaround?

I hear the pop even if I turn the MIDI volume way down.

I uploaded another version of the project to the Kontakt post.  It's pop-simple.zip.  This project is reduced to the simplest possible test case, which is 3 notes and one articulation.  The pop occurs as long as those events are present.  If you delete any event, the problem goes away.

Computer specs, sound card?

Happens on 2 different sound cards.  See sig for system specs.

you may need to raise the latency slider.

Addressed in 3rd paragraph in top post.

My suspicions were the same as yours, that it was a hardware issue.  However, it appears to be a bug in the actual soft synth.  What I'm trying to find out is if other people can reproduce the bug, and if there is a workaround.

Native Instruments says they cannot reproduce the bug, although I am not convinced they have even tried to open my project.

Can someone on here please try it?

Thanks!

Have you tried starting a brand new project, just insert Kontakt and set up your test again from scratch?

Try it and see what happens.
