... but in OS 3.0A, you do have a new drum bank (MIDI) which mirrors the AUDIO drums (however, you loose that live 'punch' and feeling only realized with audio) and here is how easy it is to do the switch/changes ...

1. Select the style (as you would with any arranger).
2. Select STYLE - VIEW (which now displays from F1-F10 the entire style parts - 2 Drums, Bass, 2 Lower/Left voices, Chords 1-5).
3. Select the part you want to change (in this case Drum1 or Drum2. It becomes highlighted waiting for your change.
4. While it is highlighted, turn the data wheel to scroll through the current bank (audio or midi - whatever it is now currently in) or press F1 to toggle to the next bank and turn wheel to scroll through Midi or press F1 again to toggle and turn wheel to scroll through USER AUDIO drums. The style can be playing when scrolling/searching through Midi drums but must be stopped to scroll through Audio.
5. If you want to change any of the chord parts, the above process is the same.
6. Like what you hear? Simply press SAVE - the style is automatically copied and saved in the HD USER STYLE folder. The ROM style remains un-altered!!

Hope this make it clearer.

Thanks,

AJ
