摘要： An electronic material instrument includes a tone generator for synthesizing tones by using a number of time-division multiplexed (TDM) modules, an input unit for programming a connection configuration (tone synthesis algorithm) for the modules of each module pair, and a processing unit for converting the input program into control data for each module and transferring the control data to the tone generator. In one embodiment, each module pair is selectively operative in an addition mode, a phase mode or a ring modulation mode, independently of the modes selected for the other module pairs. It is thus possible to attain a tone synthesis desired by the user, and to make the best use of the capacity of the tone generator.

摘要： A key scaling apparatus includes a reference data input device which is operated by a user of an electronic musical instrument to designate at least three different key numbers together with respective key scaling data for those key numbers. When a key number is supplied from a play input device such as a keyboard in the electronic musical instrument, an interpolator computes key scaling data for that key number from the data designated by the reference data input device. The computed key scaling data serve to control a tone parameter such as an envelope level which is then used in a tone generator to develop a tone for that key number. Accordingly, a satisfactory key scaling response is obtained over the entire pitch range of keyboard.

摘要： A digital audio signal prerecorded in a DAT is processed by a computer to calculate a compressed difference data array. This compressed difference data array is obtained by compression processing on the basis of a variable compression ratio depending on the magnitude of the variation of the original waveform data array. This compressed difference data array is written in a ROM as waveform data for musical tone generation, and the ROM which stores the waveform data is used as a circuit arrangement for an electronic musical instrument. The electronic musical instrument expands the compressed difference data array on the basis of expansion ratio data, and reproduces it as a waveform data array. This waveform data array is audibly output as a musical tone signal.
