The essence of mainstream hardcore sound is a distorted bass drum sound, overdriven to the point where it becomes clipped into a distorted square wave and makes a recognizably melodic tone.Often the Roland Alpha Juno or the kick from a Roland TR-909 was used to create this sound. Mainstream hardcore tracks typically include samples and synthesized melodies with the typical tempo ranging from 150 to 180 bpm."@en . . . . . . . . .
