28th April apparently.
VB3 version 1.4 recompiled to be x64 VST for Windows. There's no difference with
the 32 bit version except that the support files (VB3.ini, VB3.lic, VB3.fxp) are
now stored in the System User's path. This is to be intended as a temporary
release until the next version is ready to be released to the public. Only the
VST instrument version is available. The FX variant is not available in VST x64.
Mac users please be patient, unfortunately programming on Mac requires more
time.
Its certainly an excellent product. There were rumours of a 64 bit version way back when NI discontinued B4 II so its been a long time coming.
I would have bought it back in the day if there had been something more than a rumour of 64 bit in the pipeline. Now? well my B4 II is still working on Win 8.1 and for the most part I am running NI Vintage Organs through LX122 or Melda Vintage Rotary, sometimes with amplitube in the signal chain if I really want serious distortion.
