Well, I must be doing something right, because I'm totally grooving on the Lap Steel, and have got some good things going with it, now. The UberMod delays and some GR5 distortion have put me into high orbit. I just want to stay up all night and play! 

Did you ever get this problem fixed, Laney? 
Mine is better, but not all the way there. Its quite a bit better, but not 100% satisfactory. I never saw any  "DFD error" being emitted. The Lap Steel seems to be fine, but some things with other sustained notes are still cutting out. It seems that the velocity setting brought the improvements for me.

Do the notes exhibit cutting out right away, or does that happen after you've been playing for a while?

Not right away but , sometimes  thereafter following longer or shorter durations of playing, Greg.

And its rather random rather than a consistent pattern. Sometimes I can complete my note(s) and sometimes not.

To explain it better: This does not happen after I've been playing for a long time [minutes, hours], but starts happening almost as soon as I begin to play at various intervals and for varying durations, cutting out abruptly or after a few beats. The notes always sound off, but for how long ... that is the problem.

Hmmm, interesting. Just wondering because sometimes if I leave a sample library loaded up for a while, and start playing, the samples get cut off a second in for the first few notes. As I play, the samples get "reloaded", and things work smoothly again. So I'm wondering if it's some DFD/memory hiccup that's causing notes to drop out. When they drop out and go silent, can you see the voice/polyphony count get reduced, or does the number stay the same?

Well, I've read about that happening on the NI forums, but that does not appear to be the problem that I'm experiencing. It really doesn't make any sense how this can be happening. It is annoying though, and making it unpredictable for recording purposes.

If I play a simple sustained chord [as I just did moments ago], for instance, some of the notes will all sometimes drop off at various intervals. Of course, this is no good for making music. It could only be usable with a lot of editing being done afterward.

Hi Kreative,

Just curious here. If you're using Kontakt inside Sonar using a single midi and audio track and you record the midi notes. Have you went back to the midi track and looked at the PRV to ensure correct duration for the note and velocity events when these unexpectedly short cutoffs occur?

Kind regards,
Rick

This happens in Kontakt standalone, X1 or Studio One. It seems to be a problem completely indepent of any DAW and soley related to Kontakt.
