Claims

[Claims for Utility Model Registration] A key-on signal that detects the press of each key and indicates that one of the keys is in the depressed state, and a key that indicates that the pressed key is in the middle of being depressed. A touch response means 4 that outputs a fly signal and a key code signal representing a pressed key, and a touch data generation means 5 that measures a key jump time based on the key fly signal and outputs the measurement result as touch data. a touch value search means 3 that searches for a touch value corresponding to each touch data according to a conversion table representing a correspondence relationship between touch data and touch values for controlling the synthesizer module; and a key code signal from the touch response means 4. A specific synthesizer module 9 selected based on
a touch signal distribution means 8 for distributing and supplying a touch signal representing a touch value to a touch value search means 3; White key touch value powder means 3 for searching the touch value of the white key corresponding to
a, and a black key touch value search means 3b for searching the touch value of the black key corresponding to the touch data of the black key according to the conversion table for the black key; Key discrimination means 11 that outputs a key discrimination signal indicating whether a key is a white key or a black key.
Then, in response to the key discrimination signal, the touch data from the touch data generation unit 5 is distinguished into white key touch data and black key touch data, and the white key touch data is searched for white key values. touch data switching means 6 for distributing and supplying the touch data of the black key to the black key search means 3b; a white key constant setting means 1 that outputs a key constant signal; and a white key that represents the correspondence between white key touch data and white key touch value based on the white key constant signal and the white key conversion function. A conversion table for white keys is formed in the white key touch value search means 3a, and a black key constant outputs a black key constant signal representing a preset black key constant. Setting means 1
′, a black key conversion table representing the correspondence between the touch data of the black key and the touch value of the black key based on the constant signal for the black key and the conversion function for the black key is stored in the touch variable unit search means 3b for the black key. A touch control device for an electronic musical instrument, characterized in that a black key conversion table forming processing means 2b is attached thereto.
