For a limited time, when you buy and register a V-Drums TD-25K/KV/KVX kit, Roland will send you a TM-2 Trigger Module free of charge. Packed full of additional drum and percussion sounds, the TM-2 also lets you trigger samples so you can include vocal phrases, loops and backing tracks in your performance. It works great with acoustic drum kits too, giving you the best of both worlds. | Roland V-Drums
