Hi Tomorrow!
Set up and use the bundled OEM SoundDiver software. This will let you control everything on the jv1010 very easily. However, running SDiver in parallel with a sequencer makes it necessary to install Hubis Loopback device on your system, which isn't really an intuitive process. Help is at hand at the SoundDiver user forum http://groups.yahoo.com/group/sounddiver-users
Do a search on Hubis and with a little patience you should have things sorted.
All the best,
Magnus
