Abstract

To simulate sympathetic resonances for an electronic musical instrument, during the playing of free notes an excited notes, updating takes place of a first list (26) of free notes and their harmonics and of a second list (28) of excited notes ans their harmonics. At each activation of a free note, for each harmonic of said free note, is sought at least one identical harmonic of a note of the second list (28) and the playing of a sympathetic note is controlled with the pitch of each identical harmonic, and at each activation of an excited note, for each harmonic of said excited note, is sought at least one identical harmonic of a free note of the first lest (26) and the playing of a sympathetic note is controlled at the pitch of each identical harmonic.

Dependent claims

Process for the simulation of first sympathetic resonances for at least one electronic musical instrument adapted to generate sounds for a set of notes and to receive at least one of activation and release controls of at least one of excited and free notes, the activation controls causing the activation of the at least one of the excited and free notes and the release controls causing the release of the at least one of the excited and free notes, the process comprising:

updating, at least during each free note activation or release, at least one first list of free notes in which with each free note are associated harmonics of said free note;
updating, at least during each excited note activation or release, a second list of excited notes in which with each excited note are associated harmonics of said excited note;
for each free note activation, determining at least one harmonic of a note of the second list identical to each harmonic of said free note and differing from said free note, such that the playing of a sympathetic note is controlled at the pitch of each identical harmonic;
and
for each excited note activation, determining at least one harmonic of a free note of the first list identical to each harmonic of said excited note and differing from said excited note such that the playing of a base note at the pitch of a fundamental harmonic of said excited note and a sympathetic note are controlled at the pitch of each identical harmonic.

Apparatus for sympathetic resonance simulation for an electronic musical instrument, the apparatus comprising:

at least one input adapted to receive activation and release control signals for at least one of excited and free notes;
a memory for storing a first list of free notes and a second list of excited notes;
means for associating with the listed notes harmonics corresponding thereto;
updating means adapted to add to the first list free notes activated during free note activation control and subtract from the first list free notes released during free note release control, and adapted to add to the second list excited notes activated during excited note activation control and subtract from the second list excited notes released during excited note release control;
means for seeking, for each harmonic of each free note activated during free note activation control, at least one identical harmonic of a different note in the second list and for seeking, for each harmonic of each excited note activated during excited note activation control, at least one identical harmonic of a different note of the first list;
and
a control signal generator for playing a base note corresponding to the pitch of a fundamental harmonic of each excited note and a sympathetic note corresponding to the pitch of each identical harmonic.
