ELECTRONIC MUSICAL INSTRUMENT
Document Type and Number:
Japanese Patent JPS5833297
Kind Code:
A
Abstract:
Touch responsive control of note amplitude and harmonic content is achieved by providing each key with a touch responsive transducer. A set of attack/decay scale factors are accessed sequentially from a memory and used to establish the amplitude envelope of the generated note. The accessed scale factors are modified by the transducer output to effectuate touch responsive amplitude control. In a preferred embodiment, scale factors stored in consecutive memory locations define a piano-like attack/decay envelope. The transducer output sets the initial memory access location, so that the harder the key is struck, the greater the initial amplitude of the generated note.
