Abstract: A display such as meter panel and advertising display comprises a color image forming layer provided on a light-transmitting permanent support via a photo-polymerizable adhesive layer, and a photo-polymerizable image-receiving layer closely adhered to the color image forming layer. The display can be effectively produced by a process comprising the steps of forming a color image on a photo-polymerizable image-receiving layer of a photosensitive image-receiving material, placing it upon a photo-polymerizable adhesive layer formed on a light-transmitting permanent support to form a laminate so that the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer face each other and then exposing the laminate to light so as to closely adhere the photo-polymerizable image-receiving layer and the photo-polymerizable adhesive layer to their adjacent layers, respectively, by the photo-polymerization.

Abstract: A musical tone generating apparatus includes a position information generating device to generate musical instrument position information (PS) as plane coordinates values. This information (PS) is stored in a memory device, or selectively determined by a manual operation. The apparatus also includes an information converting device to convert information (PS) into musical tone parameter control information (PD). This control information (PD) controls musical tone source signals (S11, S12, and S13) to generate a sound field corresponding to the position of musical instruments arranged on a stage.This enables an operator to verify the musical instrument positions on a stage, thereby providing a feeling of being at a live performance.

Abstract: In a musical tone signal generating apparatus, first sampling data and second sampling data are multiplied together by a convolution operation, wherein first sampling data indicates instantaneous amplitude values of a musical tone waveform generated from a keyboard, for example. The second sampling data is obtained from an impulse response waveform signal indicative of a reverberation characteristic of room or an acoustic characteristic of amplifier or musical instrument such as a guitar or a piano. Or, the second sampling data can be obtained from a waveform signal indicative of animal sound, natural sound or the like. Then, the multiplication result of first and second sampling data is combined together into the musical tone waveform data, whereby a musical tone signal corresponding to this musical tone waveform data is generated.

Abstract: An automatic musical performance apparatus for an electronic musical instrument provides a buffer memory and a recording medium. The automatic musical performance apparatus further includes a microcomputer for executing programs for read-out and write-in operations of the buffer memory and the recording medium. The musical performance data groups generated by the electronic musical instrument are temporarily stored in the buffer memory and are transferred to the recording medium wherein the musical performance data are recorded thereon. At this time, the microcomputer detects transfer control information corresponding to a data quantity which indicates the data quantity transferred in a unit time. This transfer control information is recorded at a predetermined area of the recording medium. Next, first musical performance data group of the data quantity is read from the recording medium and is stored in the buffer memory before the musical performance data groups are reproduced.

Abstract: An automatic performance apparatus including a memory, a readout means, a musical tone generator, high and low-speed dials and a rotary encoder. The memory stores musical performance in an event style representing the on/off of a key and identifying the key and relative time data representing time between event of said key and the immediately previous event in accordance with musical performance. The readout sequentially reads out the event data from the memory. The musical tone generator is arranged such that the pitch, generation timing and termination timing of the generated musical tone are controlled on the basis of the event data read out by the readout means. A combination of dials and rotary encoders manually designates a readout direction and a readout speed of the stored data. The readout includes a circuit for exchanging the on-data with the off-data (and vice versa) in the memory when the designated readout direction is opposite to the storage order.

Abstract: A musical tone signal generator for an electronic musical instrument is constructed by a waveshape generator, a function generator and an interpolator. The waveshape generator successively generates adjacent two waveshapes of a plurality of different waveshapes which have been intermittently sampled in an actual produced tone. The function generator generates an interpolation function which is a function of time. The interpolator weights the adjacent two waveshapes in accordance with the interpolation function, combines the weighted two waveshapes and outputs the combined waveshape as a musical tone waveshape to be produced at a rate corresponding to a frequency of the musical tone waveshape. In the waveshape generator, the generation of next two adjacent waveshapes are performed when a value of the interpolation function has become equal to a predetermined value. As a result, it is made possible to obtain a good quality timewise spectrum change of the musical tone waveshape.

Abstract: Tone signals from plural keyboard systems are supplied to an effect imparting circuit via a distribution circuit. The effect imparting circuit comprises plural effect imparting channels and the device can impart a tone effect independently to a tone signal provided to each of the effect imparting channels. The distribution circuit distributes tone signals from the respective keyboard systems to any one or more of the effect imparting channels. An effect selection device is provided for selecting tone effects for the respective keyboard systems and an effect assignment device is also provided for assigning the effects selected in the respective keyboard systems to any of the effect imparting channels according to the selection by this effect selection device. The distribution circuit delivers the respective tone signals to the proper effect imparting channels respectively as controlled by the effect selection and the effect assignment.
