When turned on, the Brush Switch in the TD-30 enhances the sensitivity of the pads while you're playing with brushes. If you have a kit that has brush type sounds assigned to the pads, turning on the Brush Switch will enhance the playability and triggering. Here's how to access the Brush Switch in a Kit:
1. Choose a Kit to edit.
2. Press F2(FUNC).
3. Press F3 (BRUSH).
4. Turn the dial to set the Switch to "ON."
5. Press EXIT when you're finished. The new setting is saved in the Kit automatically.
