I owned a XV5080 for a while.The unit is great. I had it expanded with a 128meg flash card and 128 meg EDO ram, I also had the new series Concert piano board as well as the Vocal board. The sounds are unbeatible[even Kurz and Korg],It is very flexable[you do have to set it up the way you need to use]. I bought it to use with my G1000, but ,a very BIB BUT...the 5080 had timing or processing problems , when trying to do the job[replacing sounds from the G1000 but retaining the control of the G1000. Most notibaly was the slow down of tempo when using EV5 pedal to bring in a color sound...Fran
