FWIW. Here’s my “final” B3 setup. Thanks to everyone in this thread and in
Corky’s VST Organ Tips and Tweaks Page
Two funny things happened to me in my search for the best B3 for me. The first was I had a demo of B5 and yearned for the full version at $99.
SIdebar: With money being tight in these crazy times I invested the $99 to upgrade Kontakt because some libraries weren’t working with 5 anymore. It’s a long story but to get all my libraries working I have three versions of Kontakt! (5.530 - which has the “Add Library” function so I can see all the libraries that I painstakingly created. 5.541 where I can see them and they all load properly but no add library function and 6 which loads all the libraries that are only compatible with 6. Why they did this is unbenown$t to me.
I sorted that out by renaming the versions and dlls so no problems working with each or all at once.
Soooo… I went again to Acoustic Samples to drool at the B5 but this time I logged in and low and behold, I had already bought a license last year. I totally forgot. I activated and there it was!
Next, I tried my luck on IK Multimedia, where I know I have stuff. Logged in and I had just enough points to get the Amplitude Leslie for free! I opted for the 147. Somebody mentioned the Softube Saturator to place in the chain, and I already had that. I pretty much always use the Waves L1 limiter on organs and EPs so they don’t break apart when the volume and/or polyphony goes up. So I added that. This is a great limiter when set just right for the instrument in use. I can slam my arm on the B5 and get that great Hammond growl with the exact amount of distortion without breaking apart.
I use the Leslie in the B5 and the Amplitude and tweak them both to get an amazing Leslie. The B5 122 and Amplitude 127 work really well together.
Here’'s a simple shot of how I routed everything.
Thanks to everybody for posting and inspiring me to get back on the ultimate B3 journey. I think I’ve finally got it nailed now.
