Ensemble effect imparting device using a bucket brigade device for an electric musical instrument
US 3866505 A
Abstract
Several bucket brigade devices respectively constituting signal delay paths are supplied with one common sound signal obtained from one electric musical instrument such as an electronic organ or electric guitar or are separately supplied with different sound signals derived from one or more electrical musical instruments. Each of the bucket brigade devices receives the sound source signal, transmits the signal therethrough with a delay which is in accordance with the clock pulse applied thereto from a clock pulse oscillator and gives out a time-delayed signal. The delaying time is determined by the clock pulse frequency of 40 kHz to 120 kHz which is controlled by a plurality first low frequency signals having a frequency of about 0.5 to 3 Hz and a second low frequency signal having a frequency about 5 to 12 times that of the former signal and a voltage level equal to about 1/3 to 1/5 of that of the former signal. The first low frequency signals applied to the respective clock pulse oscillators are different in phase from one another. Sound signals from the bucket brigade devices are conducted through amplifiers to one or more loudspeakers, thereby reproducing musical sounds from the loudspeakers with a unique orchestra or chorus effect.

Agent, or Firm-Flynn & Frishauf [57] ABSTRACT Several bucket brigade devices respectively constituting signal delay paths are supplied with one common sound signal obtained from one electric musical instrument such as an electronic organ or electric guitar or are separately supplied with different sound signals derived from one or more electrical musical instruments. Each of the bucket brigade devices receives the sound source signal, transmits the signal therethrough with a delay which is in accordance with the clock pulse applied thereto from a clock pulse oscillator and gives out a time-delayed signal. The delaying time is determined by the clock pulse frequency of 40 kHz to 120 kHz which is controlled by a plurality first low frequency signals having a frequency of about 0.5 to 3 H2 and a second low frequency signal having a frequency about 5 to 12 times that of the former signal and a voltage level equal to about 1/3 to 1/5 of that of the former signal. The first low frequency signals applied to the respective clock pulse oscillators are different in phase from one another.
