1. Choose a Kit to edit.
2. Press the INST button.
3. Press the PAGE UP button to confirm that you're on Page 1.
4. Press the F1 button to select the INST tab.
5. Hit the pad that you want to adjust.
6. If you have hit a pad that has a Kick, Tom, or Snare instrument assigned, you can adjust the Shell Depth with the R2 knob. If you have hit a pad with a cymbal sound assigned, turning the R2 knob will adjust its size.
7. Repeat Steps 5 and 6 for the remaining pads as desired.
8. Press the EXIT button when you're finished. The new settings are saved in the Kit automatically.
