ECHO EFFECT SOUND OUTPUT CONTROL METHOD OF ELECTROPHONIC MUSICAL INSTRUMENT

摘要

The method for controlling the output level and time of the reverberation according the touch force of the keyboard to get the real effect comprises the steps of: (a) detecting and analysing the touch force of the keyboard; (b) selecting and storing the corresponding parameters like attenuation and delay rates into the DSP to process the reverberation; (c) constructing the initial reverberation and late echo corresponding the keyboard touchiness with the stored parameters; and (d) providing the reverberation data to the sound IC to generate the corresponding sound.
