Abstract
An automatic rhythm performance device is of a type in which an intro performance which is in a rhythm pattern different from a rhythm pattern of main performance to be performed amidst music progression is automatically provided at the start of an automatic rhythm performance. To provide the intro performance, this device has a memory for storing special rhythm patterns in addition to regular rhythm patterns for main performance. At the start of the automatic rhythm performance, this memory is made operable for a predetermined time period so that the intro performance is executed on the basis of intro pattern pulses read out from the memory. The intro performance is inhibited when "synchro start mode" which starts the automatic rhythm performance in synchronism with key depression is being selected.
Claims9
In combination with a synchro start automatic rhythm performance device intro control means for automatically providing an intro performance based on a predetermined pattern at the start of an automatic rhythm performance, and inhibition means for inhibiting the operation of said intro control unit when said start of the automatic rhythm performance is a synchro start in which the automatic rhythm performance is started in synchronism with key depression.
In an electronic musical instrument including keys for playing musical notes, an automatic rhythm performance device comprising:
- a first automatic performance circuit for rendering a first automatic rhythm performance under a first rhythm pattern;
- a second automatic performance circuit for rendering a second automatic rhythm performance under a second rhythm pattern;
- a start-stop control circuit including a start switch and being connected to said keys and to said first and second automatic performance circuits for controlling start and stop of said first and second automatic performance circuits in at least two modes, one being a first mode wherein automatic performance starts, upon actuation of said start switch, with said first automatic rhythm performance for a predetermined limited time period and thereafter is succeeded by said second automatic rhythm performance, whereas the other being a second mode wherein automatic performance starts, in synchronism with the first actuation of any of said keys, with said second automatic rhythm performance.
