for saving banks:
Obviously you must have the ELoader installed.
Your computer must have MIDI interface, you can't transmit using only the USB interface, this one is just for speeding the process. both MIDI plugs must be connected on the EMU and the computer. Cables must be connected before turning on the unit.
You can find the process of downloading banks on the CDROM, on the documents section, ELOADER Operation manual. The process takes a few minutes. On the EMU, just go to the MIDI menu, send patch bank, match the MIDI Device number (use 1 on both)
Sorry for the Cubase question, I don't use computer for music production, I'm 100% hardware.
About the 32 roll....
There are lots of ways for playing the 32 rolls:
take one patch. One the patch cords, assign one knob, to turn off and on the arppegio on the patch. go to the arppegio editing screen, select a arppegio pattern. If the arppegio is 1/16 based, duplicate the pattern speed.
then, you can turn on and off a32nd roll with just moving one knob.
When recording on realtime, put the quantize value on 32. With the repeat button, now you can enter 32 notes while recording.
On step grid, each time you select the repeat note, it will record automatically 23 notes.
the 32nd roll is used widely on drum & bass. I apply it on bridges and pattern transitions. Play with them, controlling the notes quantity with a knob, and with another one, increases and decreases on the volume. Also, associate the 32nd notes bridges,with discrete variations on the attac and decay level of short sounds.
I also use it on goa trance leads. Command stations can simulate VA synths, using weird patchcords on its controller programming. Fast performances of VA sounds, sound very good when applying 32nd notes. 32nd notes can be used not only on snares or hi hats, but on leads and edge sounds.
