Abstract: A musical performance data reproduction appparatus for reproducing stored performance data compensated with a just-beat function. A clock generator generates a clock proportional to a given tempo. A clock counter counts the clock to output incremental clock data. A clock converter converts the incremental clock data into reproduction clock data with a nonuniform increasing rate. The performance data is then reproduced based on the nonuniform reproduction clock data and a time base of the reproduced performance data is expanded/compressed so that reproduced tones are just-beated with respect to a reference beat time.

Abstract: A keyboard system for an electronic musical instrument of the keyboard type, such as a synthesizer, electronic piano, organ or controller keyboard. The keyboard includes an electromechanical key actuation and sensing element that in combination with electronic processing allows the performer to adjust both tactile and tone control parameters associated with keyboard touch response. The tactile response can be tuned over a broad range and is capable of simulating a light organ touch, heavier "piano key feel" or stiff percussive action. Since any of these features can be selected and adjusted while the performer is playing the keyboard, the keyboard system also has a desirable "real time" capability that does not interfere with musical performance.

Abstract: A keyboard operated musical instrument is disclosed in which the musical tones are generated by reading out a sequence of data values stored in memories. A first memory stores the musical waveshape for the attack and decay phases of the musical tone. One of a plurality of memories, each storing a period of a different waveshape, are selected by means of a touch response signal generated by the manner with which a keyswitch is actuated. At the end of the decay phase the waveshape selected by the touch response signal is read out sequentially and repetitively and is substituted for the data stored in the first memory. A means is provided to minimize the transient created in the transition between data read out of the first memory and the selected second memory. Provision is also made for a touch response loudness effect.

Abstract: A touch sensitive system for an electronic musical instrument providing a multiple key switch contact system for effecting control over two or more tone generating systems. The first tone generating system operating rapidly in response to the actuation of the key switch to produce a desired voice. The second or subsequent tone generating systems operate sequentially in a delayed manner on the actuation of the key switch effecting a predetermined delay in the production of the desired voice. The audio output of each of the tone generating systems is summed forming a resultant waveform for audio amplification. The key switch actuation, depression and release, causes the tone generating systems to respond immediately to the depression or release of the key switch which effects a change in the envelope characteristics of the resultant waveform.

Abstract: The invention relates to an electronic percussion-type musical instrument, such as an electronic piano, capable of producing electronically sounds simulating a piano, harpsichord or other keyboard percussion instrument. The keyboard is multiplexed to produce a serial time division multiplexed data stream having tri-level encoded signals in time slots corresponding to the keys, wherein the encoded signals indicate whether the key is undepressed, partially depressed or fully depressed. The amount of time for the key to travel in its undepressed to its fully depressed state is detected and a binary representation of the key velocity correlated to this timing is stored in a memory for readout synchronized with the scanning of the keyboard. In each time slot, a portion of the percussion envelope for the pertaining key is calculated and generated together with the discrete amplitude levels for the percussion envelope in a digital to analog conversion circuit. The conversion circuit comprises a digital to analog converter connected to the velocity data and having its analog output connected to the multiplying input of a multiplying digital to analog converter having its other input connected to the output of the envelope generator. The envelope keys tones from a generator in the keyer circuit to produce tones having frequencies corresponding to the depressed keys of the keyboard and velocity scaled envelopes calculated by the velocity and envelope generation circuitry. All of the processing is accomplished on a time-shared basis among the keys of the keyboard and then converted to parallel format for the keying operation.

Abstract: A brass pulse keyer for electronic instruments such as electronic organs wherein the tone during attack is both amplitude modulated and pulse width modulated. The keyer is adapted for large scale integration and comprises a timing capacitor, an electronic switch connected between a source of charging potential and a capacitor and having a control terminal which is connected to the tone input, and a second electronic switch connected in series with the charge voltage, the first switch, and the capacitor and having a control terminal connected to receive the keying envelope. A comparator compares the potential on the capacitor with a reference potential and disables a gating circuit when a compare condition is reached such that the duty cycle may be controlled. As the keying envelope continues towards its maximum, the duty cycle decreases so that a more brilliant tone is achieved. This signal is connected to the input of an analog keyer, which is also controlled by the keying envelope such that amplitude modulation of the tone may also be achieved.

Abstract: Delayed vibrato is implemented in an electronic musical instrument of the type wherein the fundamental frequency of the generated tone is proportional to a frequency number R supplied to the instrument. At the beginning of note production, the frequency number R itself is supplied to the instrument for a preselected delay time, so that no vibrato is introduced during this initial delay time. Subsequently a periodically varying fractional frequency number R.sub.v is added to the frequency number R and the sum supplied to the instrument. This causes the generated tone to exhibit vibrato at a rate corresponding to the periodicity of the value R.sub.v. The depth of vibrato is established by the maximum value of R.sub.v and may be varied by scaling R.sub.v. Advantageously such scaling is done when the vibrato begins, so that the vibrato depth will increase gradually to the maximum value.
