It’s too bad you can’t get a hold of Native Instrument’s B4 II & try it out - complete with draw bars, pedals & all.
I got it in a bundle called Komplete Classics, which included Akoustik Pianos, Pro 53 Synth, Electrik Pianos 1.5 & B4 II - all for $199.00.
Although it was a 32 bit release, [pre-64 bit days], it works just fine both in standalone mode & in Kontakt 4.2.4 in my Windows 7 - 64 Bit OS, without needing jbridge.
Maybe you can find one on KVR market place or something. Probably dirt cheap by now if you can.
You could post a ‘Wanted’ ad there, among other places, & see what happens.
I’d even consider selling mine but I just like it too much!
