There is another payed version that I like
Sonicprojects
but I only found windows version
Already have a striped down version for reaktor but I found it hard to work with

Hugs from Brazil to all mates!

 

Oops, I realized my error only too late. Sorry Catalyst.

 

The Reaktor version is pretty decent, although the presets are a little messed up and you can't really tweak the controls. I could have sworn there was a Mac version of the VSTi, though.

Whatever you do, avoid the SampleTank Xpansion Tank 2 library! Not only are most of the presets pretty awful, but there's some sort of volume issue that makes it useless.

 

I really do not understand why sampletank libs are so steril...
Sure thar Reaktor version is poor in tweaks
I already done the VFX wrap with windows version, but again is not very confortable.
I will compare with obxd, but I think that he is the winner.
