I also think the bass sounds are weak in the stock XV's- I was expecting better especially considering they went to town in improving the acoustic guitars (the best of any synth IMHO!). The bass/drum card has the BEST bass sounds out there this side of a sampler and also the drum kits contain samples not available in the stock XV's ROM- I use this board more than any other (it's in my JV1080) but I'm interested to know about the quality of the guitar and drum sounds in the COUNTRY expansion board- to me this seems Roland's answer to that supposed guitar and drums board that was to be released earlier on- I haven't heard this board yet so any opinions would be appreciated as I have one more slot in my XV3080 yet to fill!!!!!!!! Cheers.
