Ahhh .... then you will have to put it in the DRUM track.
Then from STYLE VIEW - press DRUM (F1) until the display shows MIDI DRUMS (this way, you are not using the audio drums).

There is no update yet for the AUDYA 4/5 appart from that shipped with the unit. You cannot update AUDYA 4/5 with AUDYA's 4.1b software.

Thanks,
