Electronic musical instrument apparatus

专利汇可以提供Electronic musical instrument apparatus专利检索,专利查询,专利分析的服务。并且PURPOSE: To harmonize the performance on the automatic side to the manual side by providing plural performance operators which control the performance speeds, minute changes of pitches and timbres and sound volumes of the automatic performance apparatus to the manual performance apparatus.
CONSTITUTION: When quarter notesare read out from a random-access-memory and a counter circuit 83 counts clock pulses CP
1 , the AND conditions of an AND circuit AN 4 do not hold and at this point a D type FF 88 inverts and terminal Q outputs logic value "1". Since the FF 88 is reset by the clock pulses CP from an oscillator 9 immediately after this, the terminal Q again outputs logic value "0" and in the end one pulse is generated from the FF 88 as a result. Here, the performer is able to freely adjust the period of the pulses CP because the variable resistance 81 provided to the oscillator 9 of a time detection automatic address generator control unit 8 may be adjusted by means of the knee lever, etc. of the electronic musical instrument main unit. Hence, at the time of joint performance of the automatic and manual performance apparatus, the performance on the automatic side may be harmonized to the manual side.
