Red Drum wont pick up all the hits

[MLB005]

When I hit my red drum fast consecutively, not all of the hits are picked up making it difficult to play on the higher levels. How do I get this repaired?

Go to the support website listed on the pink paper and request new drums. Be sure to select express, it's much faster.
