摘要： A waveform data storing unit stores waveform data only at steps midway among a top zero level step and originally sampled steps at every sampling period from the top zero level step. An output means is included for outputting the waveform data at a moment staggered from another moment, at which the waveform data at the top zero level step and the originally sampled steps are ordinarily read out, by a period of time corresponding to half a step. The occurrence of a difference in phase of the read-out waveform is prevented without the need of a data correction unit. The waveform data storing unit stores midway-step data which are averages of waveform data at adjoining originally sampled steps and difference data representing the difference between the waveform data at the originally sampled steps and the midway-step data. A fine waveform can therefore be obtained while using a smaller quantity of data.

摘要： An electronic musical instrument is provided with a first programmable counter for generating a reference clock signal corresponding to a musical frequency and a plurality of cascade-connected programmable counters which are each triggered by the preceding programmable counter. A multi-level signal which assumes one of a plurality of levels for each period specified by one of the cascade-connected programmable counters is output as a primary waveform. The electronic musical instrument is capable of setting various variations of the primary waveform abundantly containing harmonics and is satisfactory in the tone quality and in the degree of freedom in setting tones, and hence is of high musicality.

摘要： In one aspect of this invention, upon playing back contents, a content to be played back is selected from a plurality of contents stored in a storage unit, and it is checked for this selected content if a first playback mode that requires a prior playback confirmation operation or a second playback mode that does not require any prior playback confirmation operation is suitable as the playback mode of the content of interest. If it is determined that the first playback mode is suitable as the playback mode of the selected content, the content is skipped without being played back. On the other hand, if it is determined that the second playback mode is suitable as the playback mode of the selected content, that content is played back.

摘要： An electronic musical instrument which has a keyboard and creates a musical tone by striking keys of the keyboard, is provided with an operation control circuit and an adder both for effecting keyboard switch chattering prevent operation processing and touch response select operation processing, a timing control circuit for controlling the switching between the chattering preventing operation and the touch response detecting operation and the scanning of the keyboard switches to detect their status, a musical tone generator for performing a musical tone generating operation asynchronously with the keyboard switch scanning operation, the keyboard switch chattering preventing operation and the touch response detecting operation, and a transfer circuit for transferring touch response information to the musical tone generator. High-speed touch response detecting operation processing and chattering preventing operation processing which are difficult to execute by a CPU are carried out by the operation control circuit and the adder on a time-shared basis, and data is properly transferred to the musical tone generator which performs the musical signal generating operation asynchronously with the abovesaid operations, thereby implementing low cost touch response processing which is free from hardware limitations on the number of tones to be simultaneously produced and the generator assignment system. Furthermore, data for internal processing is set for two words on a time-shared basis, and touch response data which has such a natural temporal variation curve as is obtainable with a time constant circuit system is directly operated by the operation control circuit and the adder is then rendered to one-word external output data of high precision and resolution, thereby effectively reflecting the tough response data in musical parameters of musical tones to be created.
