Tempo controller
专利汇可以提供Tempo controller专利检索，专利查询，专利分析的服务。并且PURPOSE: To decide whether or not a tap is correct and to ignore a wrong tap by providing an inter-tap score time difference detecting means which detects a difference in score time position.
CONSTITUTION: The tempo controller 1 supplies tempo clock information to a sequencer 2 through an MIDI cable. At this time, the tempo controller 1 estimates the score time of a strong beat point that an operator intends at the time of tapping, and considers the current tap to be a wrong tap and ignores it when the score time is ≤1/2 time as long as the score time of one beat (constant:384). Then performance data are read out of the performance data memory in the sequence 2 according to a tempo clock and sent to a sound source 3, and waveform data corresponding to the performance data are outputted to a sound system 4. Consequently, even if the operator performs tapping by mistake, the tempo of an output musical sound is prevented from varying in tempo undesirably.
