Hi all,
Just tried to arrange a song and ready for offline fast bouncing in Sonar x3e in Windows 8.1. But the bounced 16bit wav audio file sounds all fine except the crackle bass sound. That is Spectrasonics Trilian 1.4.3d.


But all bass sounds good and alright when I listened in Sonar realtime.
I'd tried to load different patches whatever synth bass or electric bass, all bounce the same type of crackle sound. But all alright in realtime listened in Sonar.


So I'd created another new empty project to test and just cleanly load the Trilian only with "Clean Fender" patch.

Here was my created 4 bar test notes:

And here was the sound result:

Still sounds crackle, but it sounds very good and alright in Sonar realtime.
 
But why? What's wrong with it? and what can I do? 

I've experienced something like that with Omnisphere in the past. It was apparently my disk I/O not keeping up. Workaround: slow bounce.

but slow bounce may permeate dropouts......

Parco,
If you're not having drop outs when playing in real time, you shouldn't (and I'm reaching here) have those problems when you "slow" bounce. 
Try it and let us know if there is a difference.
Also, try to record the bass track to a separate track (don't freeze, but use the new synth record feature)..
This will tell all... (I hope).
