The integrated assembly includes a plurality of microphones arranged and electrically connected such that the resulting amplified sound is of optimal quality and of relatively constant loudness regardless of cymbal tilt.

Abstract: An electronic percussion instrument modifies the effect applied to note generated in response to a strike based on the intensity of the strike. A plurality of patches are stored in the waveform memory. Each patch includes settings for the effects applied to each pad of the instrument. The patch also includes a setting indicating whether the parameters of the effects applied to the pads are to be modified in accordance with strike intensity. Subsequently, during performance, when a strike is detected the intensity of the strike is used to determine whether the parameters of the effect applied to the note are to be modified, and if so the parameters are modified in correspondence to the intensity of the strike. This allows the performer to easily modify the effect applied to the notes of the percussion instrument during performance.
