Alot of aliasing if you combine sync whilst ring modding. So you cannot get the Ultravox sound they did with the original (I now use my Prodyssey as a set of knobs for my Nord Modular 2 if I want that Odyssey sound).I have just ordered a Prodyssey through a music store here.... can't wait....... I will speak with Juergen if I find any problems on it.....It sounds great from examples I have heard....
If you forget it is supposed to be an ARP Odyssey emul then it is fantastic and the best (IMHO) of the ASB's. If you want the Odyssey emulation forget it!
