摘要： A user interface implemented on a touch-sensitive display for a virtual musical instrument comprising a plurality of chord touch regions configured in a predetermined sequence, each chord touch region corresponding to a chord in a musical key and being divided into a plurality of separate touch zones, the plurality of chord touch regions defining a predetermined set of chords, where each of the plurality of separate touch zones in each region is associated with one or more preselected MIDI files stored in a computer-readable medium. In some embodiments, the touch zones are configured to provide different harmonic configurations of a base chord associated with the chord touch region. Some harmonic configurations provide progressively wider harmonic ranges across each adjacent touch zone. Other harmonic configurations can provide chords with a progressively higher relative pitch across each adjacent touch zone.

摘要： Process for synthesis of a synthesized audio signal, in which at least one audio signal of contact is produced for each excitation contact of a sequence of contacts carried out on a vibrating body (2). A partial attenuation signal of remanence is generated from at least one vibration signal representative of the vibration of the vibrating body (2) generated by at least one excitation contact, named partial contact, the partial attenuation signal of remanence being representative, of a partial attenuation of at least one remanent audio signal of contact, resulting from an excitation contact that is previous to said partial contact. The synthesized audio signal after said partial contact is produced by mixing the audio signal of contact of said partial contact and each remanent audio signal of contact affected by the partial attenuation signal of remanence. The invention extends to a device (3) for synthesizing said synthesized audio signal. The invention relates in addition, to a process and a device (3) for synthesis from a signal, named transposition signal, resulting from a sequence of contacts of changes in pitch of the vibrating body's (2) vibration. For at least one excitation contact of change in pitch, at least one frequency component, named channeled component, of an audio signal of contact, named tonal signal of contact, resulting from an excitation contact that is previous to said excitation contact of change in pitch, is modulated around a harmonic frequency of a new pitch, corresponding to a harmonic rank different from the harmonic rank of a preceding synthesis frequency of the channeled component.

摘要： Based on the understanding that time-varying characteristics of a tone element, such as an amplitude and pitch, in waveform data acquired through a live performance of a musical instrument include a variation component intended or controllable by a human player and a variation component not intended or non-controllable by the human player, the present invention allows the two components to be adjusted/controlled separately and independently of each other, so as to achieve effective and high-quality control. Discrete variation value train is acquired for at least one particular tone element in original waveform data, and the acquired variation value train is separated, in accordance with a time constant factor, into a “swell” value train of a relatively great time constant and a “fluctuation” value train of a relatively small time constant. The “swell” value train and “fluctuation” value train are variably controlled independently of each other. In this way, high-quality control can be performed on tone elements, such as an amplitude and pitch, included in the sampled waveform data.

摘要： Provided are an apparatus and a method for processing a bell sound in a wireless terminal capable of controlling a volume of sound source samples as the bell sound is played. According to the method, a plurality of notes, volume values, volume interval information, and note play times are extracted from inputted MIDI file. After the number of volume samples for each step is computed using the extracted volume value and the volume interval information, a volume of the sound source samples that correspond to a note that is to be played is controlled in advance using the number of the volume samples. Next, the sound source samples are converted using a frequency given to the notes and outputted, whereby a system load due to the real-time play of the bell sound can be reduced.

摘要： Basic envelope is produced for at least one tone on the basis of performance information. In response to a free selection by a user, a segment template including a characteristic variation curve is supplied, and the characteristic variation curve of the segment template is placed on a performance time axis. Then, the placed characteristic variation curve and the basic envelope are combined together to produce a synthesized envelope, and a tone is generated using the produced synthesized envelope. A plurality of segment templates of different lengths are prepared beforehand, which include phrase segment templates corresponding to lengths of phrases, note segment templates corresponding to substantial total lengths of tones, and tone-portion segment templates corresponding to lengths of portions of tones. Two or more segment templates of different lengths selected by the user are combined, as necessary, so as to permit fine envelope control.

摘要： A musical sound generating system which generates musical sounds having desired tone regardless of the variation of volume setting. In the musical sound generating system, the standard tone control touch curve TCstd, the maximum tone control touch curve Tcmax, and the minimum tone control touch curve TCmin when the amplification factor V is standard (a standard amplification factor Vstd), maximum, and minimum respectively are stored. If the amplification factor is higher than the standard amplification factor Vstd, an interpolation between the standard tone control touch curve TCstd and the maximum tone control touch curve TCmax is performed, and the tone control touch curve TC according to the amplification factor V is obtained. Based on the tone control touch curve, the cut-off frequency F corresponding to the velocity value Tv is determined, and then the tone of the musical sound is controlled by the low pass filter with the cut-off frequency F.

摘要： An electronic keyboard musical instrument is responsive to a step-on of a soft pedal so as to impart effects similar to those of a soft pedal of an acoustic piano to an electronic sound; a tone generator incorporated in the electronic keyboard musical instrument causes a series of waveform data codes to be read out at a higher speed so as to slightly increase the pitch of an electronic sound, an envelop generator to give a gentle envelop with a small attack and a long sustain to the electronic sound and a filter circuit to emphasize a certain high frequency component, thereby making the electronic sound to be quite close to the piano sound produced under the step-on of the soft pedal.
