how to get a B3 sound? its easy
As an owner of 5 Hammonds and 4 Leslies let me say that there is no way to duplicate the sound with anything but a Hammond and a Leslie. You can get some of the sounds with samples and stuff like Native instruments software... but even this falls short because of the numerous changes to drawbars, presets, leslie switching, percussion, vibrato/chorus that are made on the fly
I do have midi on an older Korg that does have a few nice sounds... but I gave up and bought a C3/122..... there are still deals out there.
Might I recommend an M3, M100, or L100 if you are on a budget.... these all take the 145/147 leslies.... once you have it you will never be satisfied with samples...
good luck....
