I tried the free version fot his with just presets and thought the sound was totally there so I bought the big version.... I've been really happy with its vibe, however I just don't seem to use it that much. I wish someone made a good matrix/xpander. Arturia is the only option and everyone who really knows the xpander series knocks on it. I sometimes regret selling my Matrix1000 even though it was so limited compared to its big brothers :-( Well, the 2 OBX type plugins I have right now will have to do for oberheim poly sounds. At elast I have the oberheim 12dB filter on my SE1 and I can do a voice stack with my SEM if I wanna tolerate the noise.... grumble.
