Hi Cosmic,
I'm assuming you were referring to your question:
Also I still wonder if the XV5080 will be able to convert load these extra JV880/JD990 patches on an exp board like the vintage synth....
If you're talking about an expansion board like the regular expansion boards installed on a JV-2080 or JV-1080, then the answer is yes. All of the JV expansion boards (I think there is somewhere around 16 or 17 or them now) will work with the new XV series synths.
I'm still going to kick it's wheels a little bit but I'm pretty sure I'll upgrade at some point to it. I'm not very happy with the JV-2080's midi timing and am hopeful that they fixed this on the XV-5080. Also, I already have a decent library of Roland CD-Roms and Zips that I will load into it.
I sold my S-760 to buy a E-mu E5000 Ultra so I could load more samples at a time (and more polyphony too). If I had known about the 5080 at that time, I would have held off on that decision. I'm happy with the E-mu though.
Oh well,
Fernando
