Hello, I am samurai in Tokyo.
I can speak English a little, but I post here because I listened to the good news in Japan (here is the main factories of Roland and new products release first in the world).
The news is: Roland Japan has stopped making JV-2080 and groove sampler since December 1999. And this suggests that Roland will release new alternative synthesizers soon = NAMM Show in Los Angels is to hold on the next February).
We (Japanese synth users) are waiting for new Roland's synthesizers and samlers with R-BUS or 24bit D/A Converter.
