I recently bought into Kontakt-5 and the Vintage Organs plugin because I assumed that NI would naturally transfer all of the great features of the B4II plugin to the Vintage Organs plugin, at the same time giving it 64-bit compatibility. Unfortunately it does not. Here are some of the reasons why: B4II has much more flexible Tonewheel options (emulating organs of different ages and conditions). B4II has much more flexible options for Percussion, Vibrato, Treble rotor, Bass rotor, Microphone place, Reverb and Bass pedals. B4II has much more flexible Controller assignments that enable me to map the drawbars and other controls on my hardware Viscount DB3 Organ keyboard to the B4II. The fact that VO can not do this is particularly annoying as I can no longer use my keyboard with VO - it only supports NI B4D (DISCONTINUED!) and the Doepfer D3C (very hard to get, has no playable keyboard and is very expensive). B4II has much more flexible Drawbar options. B4II has a much better collection of supplied organ sounds. B4II has much better Preset management options. Giving the new plugin the same wooden skin as B4II is not enough - it also needs to be at least as good as B4II ! @NI: Any plans to improve VO?
