Well, I'm an happy NI B4 owner, Vintage sounds enthousiast and I always love to test to "virtual vintage" stuff. I had already been testing the Organized trio last year and I found it very cheezy sounding, 2.1 just got out and it's really interesting. First of all it has very good tube amp sim, works really fine. I'm used to get the B4 into the simulanalog guitar suite to get some crunshy organ sound, here you can get some out of the box. The tonewheels sim is not perfect, in fact it's not as closed to the real thing as the B4 is, but it's really interesting. You can get sounds like M100s and transistors Hammonds, and the beautiful things is Low freq, really deep, works really good. The Keyclick is very bad contact style but works fine, as the percussions. The Vibrato sounds a bit cheezy, Chorus is far better. The Leslie Sim is not the best part of the software, after 5 minutes I got the mda Leslie in place of it and got far better result. You have there also things you don't have on B4, the appreciated Midi remapping functionnalities. Here is a great freebie a good workhorse for those who need an organ sound sometimes and also a good second tool to get some organ sounds the others can't do.
