Electronic musical instrument controlling impartment or non-impartment of effect in synchronization with start of tone generation

An electronic musical instrument comprising:

• tone generation instruction means for designating a tone and instructing that the tone should be generated;
• effect selection means for selecting a predetermined effect;
• tone generation means responsive to outputs of the tone generation instruction means and the effect selection means for generating a tone which is imparted, or not imparted, with the predetermined effect with respect to the tone designated by the tone generation instruction means depending upon whether an effect has been selected by the effect selection means or not;
• and
• control means for inhibiting, when an effect has been selected or the selection has been released by the effect selection means, a change of a tone being generated by the tone generation means to a state where the predetermined effect is imparted or to a state where the effect is released during generation of the tone.

An electronic musical instrument comprising:

• tone generation instruction means for designating a tone and instructing that the tone should be generated;
• effect selection means for selecting a predetermined effect;
• means for deciding, when the tone designated by the tone generation instruction means is assigned to a tone generation channel, whether the predermined effect should be imparted to the tone or not depending upon whether an effect has been selected by the effect selection means or not;
• and
• tone generation means for assigning, in accordance with this decision, a tone which is imparted, or not imparted, with the predetermined effect with respect to the tone designated by the tone generation instruction means to a tone generation channel and generating, in accordance with this assignment, the tone which is imparted, or not imparted, with the predetermined effect in the tone generation channel.

An electronic musical instrument comprising:

• tone generation instruction means for instructing that a tone should be generated;
• effect instruction means for instructing to impart a predetermined effect to the tone;
• tone generation means for generating tone signals in response to instructions by said tone generation instruction means;
• effect imparting means for imparting the predetermined effect to tone signals generated from said tone generation means;
• and
• control means for controlling said effect imparting means in such a manner that the predetermined effect is imparted only to a particular tone signal corresponding to a tone for which start of generation is instructed by said tone generation instruction means after instruction by said effect instruction means that the predetermined effect should be imparted.
