I am using a TI bass sound amongst a wealth of other synth plugins in a current project in FL9, when I play the project out of FL, it sounds awesome.
So now I export it as either *.wav ormp3 and all plugins sound awesome with the exeption of the TI plugin, which is all grainy and chopped up.
I have tried a variety of settings in the ASIO settings and different quality or recordings, always with the same result.
Remember that the TI is 48Khertz and maybe you trying to export 41,8Khertz that could cause problems. You also have to export in live mode. (so playing the entire song in it's normal state and export).
Otherwise you get what you have now.
