Anyone used latest IK b3 version?

Anyone used latest IK b3 version?
Is it any better on cpu usage?

You can test it but probably not…

I am on the latest B-3X and it’s still a cpu pig (at least on Windows), but it sounds great. It is my #1 B3/Leslie emulation plugin despite the resource issue. For the record, Blue3 with IK’s Amplitube Leslie consumes as much cpu as B-3X alone.

Is ik b3 usable on its own in a single rackspace,
Can you play 2 x 5 finger chords without glitching?
Does it switch patches instantly or is their a delay

Yes you can play this chords and yes switching between rackspaces is glitch free.
