When comes to keyboards, real or virtual, I'm not making such a big issue over the fact that are synths or samplers/ romplers.
For me, as a musician, a certain instrument have a certain place as a music constructing element.
I compose music, I don't compete in the "I tweaked this button too" contest. Those been said, here's my addition to this beautiful thread.
========================
Vintage Sound - Hammond Organs
As part of Jazz/ Blues and Rock culture, Hammond Organ (an electric organ which was invented by Laurens Hammond in 1934 and manufactured by the Hammond Organ Company) is a landmark in sound. Doesn't matters if you listen to Joey De Francesco or Deep Purple, Yes, Emerson Lake & Palmer or some more modern rock such as Dream Theater, the classic Hammond sound is there.
Classic Hammonds utilized oscillating vacuum tubes, manipulated sine waves through the use of harmonics, could actually save preset sounds, had modulation control, (the two Leslie speeds and the different tremolo, chorus, and vibrato settings), had attack and decay parameters, volume pedal control, and even had echo and sustain available on later models. Doesn't that sound a lot like the early synths we know?

Hammond Organs as VSTi
Native Instruments - B4 II - $229 / 199 EU
The B4 combines the classic and robust tonewheel organ and rotating speaker sound with the convenience of software. A tube amplifier and a selection of classic speaker cabinets offer you greater freedom of expression.

VB3 The Ultimate Virtual Tonewheel Organ - 49.00 EU
VB3 is a virtual tonewheel organ which simulates an american electromagnetic organ of the old days, but it's also capable of other simulations like the italian transistor organs of the seventies or the red-tolex organs played by famous pop bands of the sixties.
In DEMO mode you'll hear a white noise burst for 2 seconds every 10 at a very low volume.
ORGANized trio - FREE !!!
This is actually the free version of "VB3 The Ultimate Virtual Tonewheel Organ", made by the same company and offered as donationware. This come as part of Legacy donationware plugins from SoundFonts.it.
I personally use it, the capabilities are amazing. Beside a nag screen appearing every now and then, there are no limitations. For a donation to them, Wikimedia or Red Cross, you can get rid of that too.
Master Hammond B3 - US$35
Tried the demo, not really convincing to be "a Virtual Hammond VST plug-in with a rich and authentic sound based on the legendary B3." but is not bad either. Guess is what you pay for.
Coming as DX, Windows VSTi, Mac VST, AU, RTAS.
LightBag Organ VST 2 PC - FREE !!!
FREE Hammond organ clone plus(separate)Leslie effect. Made with "Synth Edit" by
Istvan Kaldor. Didn't tried yet but have good reviews.
Bojo - Organ One - FREE !!!
16 voice polyphonic,9 drawbars/2 oscillators in each voice, LFO with 8 different waveforms (incl. random). Coming as Windows VSTi.
Tried it, quite cute and sounds decent enough to use.
Rumplerausch made several great plugins, mostly donationware or free. I remember that like 5 or 8 years ago I tried several Hammond like plugins, quite impressive... Now up on his website are:
Rumplerausch - AZR3 - FREE !!!
Vintage drawbar organ emulator. Features three "keyboard" channels, a versatile distortion effect and a rotating speaker emulation.
Rumplerausch - CRAZY DIAMONDS - FREE !!!
Coming as Windows VSTi.
This stuff is free of charge, but you are kindly asked to donate for a globally acting NGO of your choice if you decide to use them.
I recommend Amnesty international, Medicins Sans Frontieres and Greenpeace.
GTG SYNTHS have tons of synths, mostly FREE, great stuff, some quite nice drum romplers too.
GTG MicroOrgan MK III - FREE !!!
Another free and quite good tonewheel-organ simulator. Coming as Windows VSTi.
NuBi LE - FREE !!!
As you can see, the links on KVR are dead :(
On the sounding practically corresponds Native Of instruments B4 and GSi Of oRGANized of trio, that also is not surprising, since it was developed as commercial product. However, in the fall of 2006 developer made his free and sent in the free floating.
Considering that the official site of NuBi3 ended its existence, entire packet is floating HERE.
Land of Cockaigne - Phibes - FREE !!!
"It is definitely no Hammond B3 or Vox Continental but rather some obscure and cheap east-european imitation of them."
As KVR says "No Longer Available" ... :( but you might still find it floating on Internet.
Organaut - FREE !!!
Classical tonewheel organ emulator. Can produce «analog» and «digital» sound.
9 drawbars
Rotary cabinet emulation
Keyboard «click» emulation
Internal reverb
Octave shift
To me, that is the most not convincing plugin, can be used but you might get better results tweaking a 3X Osc and put on effects a chorus and autopanner... oh, by the way
3X Osc - bundled with Fruity Loops
You can take any simple sine and with a chorus and autopanner you'll get a quite ok sound, suitable for harmony more than solo but good enough.
More to come later.
Happy music making !
