There are 100 drum kits in the TD-15 (1-50 are Preset / 51-100 are user). Here’s how to select one.
1. Press the DRUM KIT < or > buttons to select the desired kit. To scroll quickly through the kits, press and hold the button. For an even faster scroll, press and hold both buttons simultaneously.
Tip: You can also turn the main dial to select kits.
