FREQUENCY MODULATOR FOR ELECTRONIC MUSICAL INSTRUMENT |
摘要 |
A keyboard operated electronic musical instrument is disclosed which has a number of tone generators that are assigned to actuated keyswitches. A tone generation computation means is implemented using a combination of an even symmetric function and an odd symmetric function. One of these functions is scaled in magnitude in response to a modulation control signal. The scaled and unscaled functions are combined to produce a musical waveshape which is frequency modulated by changes in the level of the modulation control signal. |
