'An electronic musical instrument with the form of antenna - synthese2'

摘要

in an electronic musical instrument is the musiktonsynthese by controlling the harmonischenanteile touch a keyboard pressed key according to a fixed information provider.a parameter rechenschaltung (13) recognizes the harmonischenfrequenz the frequency of the fixed information provider on the next adjacent and produces fm rechenparameter using the next adjacent harmonischenfrequenz as a carrier frequency and a fundamental wave or a harm onischenfrequenz the selected note as a modulation frequency.a frequenzmodulationsschaltung (16) on the basis of these parameters, a fm account and there will be a sound is generated, the harmonischenanteile according to an information provider are controlled, the mittenkomponente the next adjacent harmonischenfrequenz.the parameter rechenschaltung (13) calculates the frequenzdifferenz between the next adjacent harmonischenfrequenz and the mean frequency of the fixed information provider to control the amplitude of a frequenzmodulationsschaltung according to this frequenzdifferenz synthesised information provider.this is done by controlling a amplitudenkoeffizienten amplitudensteuerung a clay or the modulationsindex to fm account. as a subformant mittenkomponente another harmonischenfrequenz in the proximity of the next adjacent harmonischenfrequenz exhibits relatively low amplitude can be formed by the information provider to the subformanten
