Hi,
origin version could eventually be done with an Acces Virus (which I sold because I couldn´t hear these trance sounds anymore... now I wish I never did do that ). But you can emulate these sounds with the PC3:
I would try to program this sound by using one of the trance super saw programs by GergorDe as a starting point (thanks at GregorDe, these sounds are really beautyful; download at sonicmatter.com) and modify it by using different octave settings of the layers with a lot of detune of the saw. Quiet fast envelope settings, rest to be done by using chorus and hall. Filter modulation set to velocity or modwheel. Other possibility could be done with triple saws or super saw combined with pulse width modulation). A little pitch modulation is also been heard. The more layers you use, the better the result. In two or three weeks I maybe have time to do an attempt for this sound.

Regards

Joerg
