Abstract
A resonant effect apparatus for an electronic musical instrument includes a plurality of resonant tone signal forming channels for forming a plurality of resonant tone signals different in their resonant frequency characteristics when applied with a musical tone to be generated and a plurality of acoustic conversion systems for acoustically converting each of the resonant tone signals to issue the converted resonant tone signals therefrom. In the resonant effect apparatus, a supply condition of the resonant tone signals to the acoustic conversion systems is controlled for control of a sound localization of the resonant tone signals.
Claims5
A resonant effect apparatus for providing a resonant effect to a musical tone in an electronic musical instrument, comprising:
- a plurality of resonant tone signal forming channels for forming a plurality of resonant tone signals different in their resonant frequency characteristics when applied with a musical tone signal to be generated;
- memory means for memorizing a plurality of resonance control parameters for control of each sound localization of the resonant tone signals;
- control means for controlling each of the resonant tone signals based on the memorized resonance control parameters;
- and
- a plurality of acoustic conversion means for acoustically converting each of the controlled resonant tone signals to issue the converted resonant tone signals therefrom.
A resonant effect apparatus for an electronic musical instrument including means for designating a tone pitch of a musical tone to be generated, musical tone forming means for forming a plurality of musical tone signals at different tone pitches designated by said designating means, and a plurality of resonant tone signal forming channels for producing a plurality of resonant tone signals different in their resonant frequency characteristics in response to the musical tone signals applied thereto from said musical tone forming means,
- wherein weighting means is arranged at each input side of said resonant tone signal forming channels to weight the musical tone signals applied thereto from said musical tone signal forming means in accordance with a difference between each tone pitch of the musical tone signals and each resonant frequency data for control of the resonant tone signals and to mix the weighted musical tone signals for applying the mixed musical tone signals to said resonant tone signal forming channels.
