摘要： There are provided first and second tone signal generation channels for respectively generating tone signals having waveshape characteristics corresponding to parameters assigned thereto. Tone color change control information such as key touch data is applied to a parameter assigning circuit. The parameter assigning circuit selects two parameters from among three or more parameters which are different from one another and assigns the selected two parameters to the first and second tone signal generation channels respectively. Tone signals having different characteristics, which are determined by the assigned parameters, are generated from the respective channels. The tone color change control information is further applied to an interpolation circuit connected to the first and second channels. The interpolation circuit interpolates the generated tone signals in accordance with the tone color change control information. A result of the interpolation is outputted as a tone signal for a tone to be produced.

摘要： A new, performer played, real time, multitonal, multimbral musical instrument consists of speed and force sensitive keys in which time domain multiplexing is used to find and associate one and only one tone generator, not otherwise busy, with any key that is depressed. The sound generator disclosed can provide very realistic simulations of the flute, oboe, trumpet, French horn, trombone through the provision of various types of modulations in amplitude and frequency of the various partials, as is characteristic of each instrument simulated, and filtered noise. Glissandi are provided from one note to another and are controlled from the pair of keys involved by the relative pressure with which they are depressed. For the nonpercussive tonalities, the speed with which a key is depressed, which is determined by differentiating the force, may be used to cause the attack transient to behave in a manner very characteristic of the instrument being simulated. The force with which a key is depressed is determined from the rate of rise of the potential across a capacitive keying system excited through a resistor. Percussive sound generators are provided also; the intensity of the notes generated by these generators is determined by the speed with which the associated key is depressed. The force with which the associated key is depressed can be used to determine the rate of automatic repetition of the note. The speed with which a key is depressed can also be used for nonpercussive instruments to alter the character of the attack transient.

摘要： An organ is described in which a small number of note generators, each comprising a binary divider, a group of keyers, and an envelope generator, serves an entire keyboard. Each note generator is selectively operable by multiplexed signals from a keyboard to produce either of two adjacent notes in any octave interval. Six of these note generators are provided for each manual of a spinet size organ. A seventh note generator, which is selectively operable to produce any of the notes available from the other six, is provided together with selection circuitry which causes the seventh note generator to augment any one of the other six which is called upon to produce two adjacent, or two octavely related, notes simultaneously. The pitch of all notes is determined by a set of top octave dividers which drive the binary dividers individual to each note generator. Synchronizing circuitry is provided to control the phase relation between binary dividers, when they are driven by a common source, to avoid cancellation effects.

摘要： A tone generator includes a plurality of tone generation channels each comprising one or more operation channels. One operation channel performs basic operation of a tone signal computing operation (e.g., FM or AM) and a tone signal is generated by using one or more operation channels for one tone generation channel. Tone generation channels in the tone generator are established according to a selected performance mode. In a first mode, the operation channels are divided into N groups and N tone generation channels are established in correspondence to the respective operation channel groups. In a second mode, the operation channels are divided into M groups and M tone generation channels are established in correspondence to the respective operation channel groups wherein N is a different number from M. Tone generation channels of the number required according to the selected performance mode can be established by efficiently utilizing the operation channels of a limited number.

摘要： An electronic musical instrument of a channel assignment type wherein depressed keys from among a larger plurality of keys are respectively assigned to a smaller plurality of tone producing channels for generating wave of musical tones. The assigner comprises a microprogram, an arithmetic section, a memory, and an interruption control circuit to assign the depressed keys to available tone producing channels. The current on-off information of the keys is subjected to calculation to form a key-on request file and a key-off request file. A tone request file is formed on a plurality of tone data as designated by the tone levers. A channel assignment table is formed, based on the key-on and key-off request files, to indicate a status of assigning the depressed keys to the tone producing channels. The channel assignment table is stored in the memory and the contents thereof are supplied to the wave generator, whereby a plurality of musical tones are generated simultaneously by the wave generator as controlled by the microprogram.
