LE 4 midi output problem with JV 1010

Was happy to see that Cubase LE 4 has a patch for my Roland JV 1010 synthsizer module. Was able to import midi tracks from Band in a Box and switch the output to the instruments I wanted without problems. But when I tried to record my own tracks, using the 16 midi tracks template, every track plays the same instrument. I tried different channels with the different instruments, but the same result.

I noticed the Band in a Box midi file that I imported had Track 1 with no note data, only all channels selected. Is that the key to successful routing?

A last question: Is the patch for the JV 1010 included in later versions of Cubase? Using a synthesizer is a bit old-fashioned, but I would hate to be without it or manually enter the patch bank data.
