I've tried everything out there and nothing has what the B4 has. " Da Organ " is good, but not quite as good as the B4, as far as my tastes v questor. In fact, I think the freeware Z3 is as good as Da organ.
I looked at Charlie, and can hear the demo tunes, but if they don't give me a working demo to test it out myself, no thanks, I'll stick to my B4. Nothing out there "blows it away".
I will give Spectrasonics their due though. Their USB ( Ultimate Sound bank ) series of sounds is excellent for someone who'd prefer to use a soft wavetable synth ( rompler ) vs hardware ( Motifs Fantoms etc ).
