In X2, this softsynth keeps playing back with messed-up timing, i.e. notes starting too early or too late. But it still works properly in Sonar 7, so lately I have been working with it using Sonar 7 and exporting it as audio. This is a bit inconvenient though. Is it just me or is anyone else having problems with this VSTi?

I am using the 64 bit version in X3e and it has replaced my old worn out B4! It is working beyond fine! I do not have the 32 bit version so I can't say about it.

Same here. VB3 64bit on X3e no issues. I have also used the x86 (32bit) version prior to x64 being released. Both worked better than expected.

I wasn't even aware of a 64-bit version. I should check this out.
