Actually I've never played with an original J8, so I can't make any real statement about the VCOs. I've heard and saw a few examples on Youtube etc., and these are really another dimension in comparison with the J8V from Arturia. Actually I don't expect an 1:1 emulation, but I expect at least improvements in newer versions and this was certainly not the case with the 1.1 Version. The effects like distortion sounds ugly now, and the filter also didn't get better, but worse. I made many 1:1 comparisons in "Live" with the 1.03 Version an the 1.1 update. (I installed both, but I'm only using the 1.0.3 Version). Also the "pure" presets without effects are different. All I want is an proper working Version of the 1.0.3.
This makes me think about hardware again. Especially when you get a good (working) hardware synth (Blofeld) for the price of two (more or less working) Arturia Synths meanwhile. Come on Arturia...
