Not sure what your after, A manual for the Juno, or Cubase...
I think Roland are making some of their manuals available online now, not sure if the Juno range will be there yet (if at all)
Have you a MIDI interface connected to your computer?
I know that the Juno Alpha's where very early MIDI devices, so I expect that it will be transmitting and recieving on MIDI channel 1.
You may well need to set the Local Control on the Juno to OFF if your using the Juno as your master keyboard.
BTW - The Alpha 1 doesn't generate note velocity, but it will respond to it..
