- 12. An electronic musical instrument as claimed in claim 1 or claim 7, wherein said second detecting means detects said second musical tone volume from an envelope level of said second musical tone.
- 13. An electronic musical instrument as claimed in claim 3 or claim 7 wherein said factor is a value corresponding to musical tone intensity, the interval between said first and second musical tones, musical tone pitch, and musical tone quality.
- 14. An electronic musical instrument as claimed in claim 13, wherein said factor is a value to which a random value is further added.
- 15. An electronic musical instrument as claimed in claim 13, wherein said factor further corresponds to a number of musical tone higher harmonics.
- 16. An electronic musical instrument having musical tone generating channels, said instrument comprising:
- a first detecting means for detecting whether or not a first musical tone which is assigned to be generated by one of said musical tone generating channels in response to a new key-press and a second musical tone which already has been assigned to be generated by one of said musical tone generating channels and is being generated thereby in response to a previous key-press are consecutive beats of the same musical tone by the same key,
