A musical sound signal generation device continuously connects any one of a connected zeroth delay unit and a connected second delay unit to a fractional delay block and connects at least any one of a new zeroth delay unit and a new second delay unit to at least any one of the fractional delay block other than the fractional delay block connected to a new first delay unit in response to setting any one of the connected zeroth delay unit and the connected second delay unit as the new first delay unit, setting a delay unit in a preceding stage of the new first delay unit as the new zeroth delay unit, and setting a delay unit in a subsequent stage of the new first delay unit as the new second delay unit in accordance with a change in a designated tone pitch.

A method creates a virtual ensemble file by receiving, at a central assembler node, recorded performance files from a recording node(s). The recording nodes generate a respective one of the performance files concurrently with playing a backing track and/or nodal metronome signal. Each performance file includes audio and/or visual data. The assembler node generates the ensemble file as a digital output file. Another method creates the ensemble file by receiving input signals inclusive of the backing track and/or metronome signal at the recording node(s), and generating the performance files at the recording node(s) concurrently with playing the backing track and/or metronome signal. The performance files are transmitted to the assembler node. A computer-readable medium or media has instructions for creating the ensemble file, with execution causing a first node to generate the performance files, and a second node to receive the same and generate the ensemble file.

A resonance signal generating method includes generating a first resonance signal of a first pitch circulating through first loop processing by inputting a first excitation signal to the first loop processing including first delay that delays the signal by a time corresponding to the first pitch and first attenuation that attenuates the signal, the first pitch being a pitch having a resonance frequency of a predetermined speaking length of a piano, generating a second resonance signal of a second pitch circulating through second loop processing by inputting a second excitation signal to the second loop processing including second delay that delays the signal by a time corresponding to the second pitch and second attenuation that attenuates the signal, the second pitch not being a pitch having a resonance frequency of any of speaking lengths of the piano or a pitch of a harmonic thereof but being higher than the first pitch, and outputting the first resonance signal circulating through the first loop processing and the second resonance signal circulating through the second loop processing.
