A standard drum machine with a realistic and natural sound With 233 realistic and natural sounds, each one is available in both dry and reverb versions. The SR16 also features Alesis' unique Dynamic Articulation function, which changes the drum sound depending on how hard you play, just like a real drum. The 50 preset patterns are not programmed, but are actually performed by top studio drummers. Each pattern has rhythmic variations (A, B, Fill) that are extremely useful when composing and arranging, and patterns and songs can be customized and saved by the user.
