    摘要： A signal processing apparatus has a first memory in which plural pieces of FIR coefficient data used for implementing an FIR filter algorithm are stored, a second memory which stores plural pieces of input data to be subjected to the FIR filter algorithm, and a processor implements the FIR filter algorithm using the plural pieces of FIR coefficient data stored in the first memory and the plural pieces of input data stored in the second memory as many times as the number corresponding to a designated filter order, in which filter algorithm each piece of coefficient data and each piece of input data are multiplied together and resultant products are summed up. The signal processing apparatus is provided, which can implement plural sorts of FIR filter algorithms of filter order which can be changed flexibly.

    摘要： For a parameter used by a tone generator unit to generate an audio signal, type of an effect to be given to the audio signal and degree of the effect to be given to the audio signal are set according to an operation of a panel strip which functions as a combination of an increase control decrease controls with an upper cursor part and a lower cursor part. This setting is made so that when an operation to further decrease the degree of the effect to be given to less than zero is detected, the type of the effect to be given to the audio signal is changed.

    摘要： A detuning control circuit is provided for producing a pitch variation effect in an electronic musical instrument. The instrument includes at least one integrated circuit tone generator chip having at least one tone generator and a detuning circuit responsive to a predetermined detuning control signal for detuning the signals produced by the tone generator. The detuning control circuit comprises a detuning control signalling circuit for producing a predetermined detuning control signal and for selectively applying the predetermined detuning control signal to the detuning circuit of the tone generator chip so as to produce a predetermined pitch variation effect.

    摘要： A continuously varying electrical signal representing an original musical sound is divided at a selected mid-frequency of about 800 Hertz to provide upper and lower frequency signal bands which are then frequency-modulated with separate modulation signals that differ in frequency or amplitude or both, in order to produce a vibrato or tremulant effect and thereby enrich the harmonic content of the musical sound.In order to inject the vibrato or tremulant into each signal band, the modulation process utilizes a pulse sampling and delay circuit which minimizes clock pulse noise by selecting only the central part of each delayed pulse, and which also senses the original amplitude envelope of the unmodulated wave in order to augment the envelope that is recreated from the delayed pulses after they are recovered.The resulting modulated signals are recombined, producing a cross-modulation which adds further harmonic components, and the composite signal is again divided at a frequency of about 200 Hertz into high and low frequency output signals which are supplied to respective high and low frequency stationary loudspeakers.

    摘要： A tone generator for use with an electronic musical instrument includes a binary counter operated by a binary comparator and a source of clock signals for incrementally advancing or decreasing the state of the counter from a first selected state to a second selected state. The states of the counter control a programmable divider which develops corresponding output tone signals. The counter produces multiple state changes between the selected states so that each individual state change results in a frequency change which is inaudible. The overall effect is to thereby synthesize a tone signal creating the illusion of a continuous pitch change between the pitches corresponding to the selected counter states. The source of clock signals includes a rate multiplier programmed according to the states of the counter to compensate system operation for insuring that similar musical effects defined by corresponding musical intervals are produced in equal time intervals. In a vibrato mode, a second rate multiplier is provided to insure that, for a given frequency output tone signal, different vibrato depths result in vibrato cycles of equal time intervals.

    摘要： An electronic musical instrument incorporates apparatus for producing, on either a triggered or a repetitive basis, a wave form which is employed to produce a variety of musical sounds upon being connected to a loudspeaker. The generator is provided with means for independently modifying the wave shape and frequency of a repetitive signal, each without changing the other.
