I have two Vintage Pro models and a Proteus 2K. if anyone has any that they want to part with, let me know. I'm looking for ONE more ROM to completely MAX out my modules. Let me know if you want to part with the Project ROM. Yes, the Xtreme LEad ROM is very nice for synth sounds. Not sure I could strongly recommend it for much else. I find myself using it mainly for percussion: the sampleset compliments the percussion in the World and Beat Garden ROMs nicely. I also have the Ensoniq Project ROM (not for sale).
