Electronic musical keyboard instruments with variable touch sensitivity
First Claim
1. An electronic musical instrument having a keyboard, comprising:
- a plurality of keys;
a plurality of musical tone signal generation systems, to which different tone groups are assigned respectively for respectively generating musical tone signals each having a tone pitch corresponding to a depressed key among said keys and having a tone color belonging to an assigned tone group, each of said tone groups including at least two tone colors having parameters representing predetermined characteristics of musical tones, at least two tone groups in said tone groups being selected under one key depression to generate at least two tones of said selected tone groups;
touch data producing means for producing touch data representing a degree of depression of said depressed key;
touch sensitivity setting means for setting respective touch sensitivities representing sensitivity to a key touch for said musical tone signal generation systems;
touch data modifying means for modifying said touch data in accordance with each of said touch sensitivities and for delivering modified touch data for each of said musical tone signal generating systems; and
control means for controlling a characteristic of each of said musical tone signals in accordance with a corresponding one of said modified touch data.

Abstract
An electronic musical instrument having a keyboard, includes a plurality of keys, a plurality of musical tone signal generation systems, a touch detector for producing touch data representing a key touch accompanied by a key depression, a panel operation unit for setting a touch sensitivity representing a sensitivity with respect to a key touch for each of the musical tone signal generation systems, and a register unit for modifying the touch data in accordance with the touch sensitivity corresponding to each of the musical tone signal generation systems. Different tone groups are assigned to the musical tone signal generation systems, and a musical tone signal which has a tone color belonging to the corresponding musical tone group and a pitch corresponding to a key depression is produced from each of the musical tone signal generation systems. Each musical tone group includes at least two tone colors having a common attribute. The musical tone signals from the corresponding musical tone signal generation systems are controlled in accordance with the modified touch data corresponding to the musical tone signal generation systems obtained from the register unit.
