1. A signal processing device configured to be connected to a remote signal processing device that is remotely located from the signal processing device via a network, the signal processing device comprising:
an electronic controller including at least one processor, the electronic controller being configured to execute
a reception unit configured to receive second time-series data, the second time-series data being generated based on first time-series data of a performance in which a predetermined musical piece has been played, the second time-series data including at least data indicating a timing of the performance;
a generation unit configured to generate third time-series data, which make the timing of the performance visually recognizable, based on the second time-series data received by the reception unit;
a processing unit configured to output an output signal based on the third time-series data such that the timing of the performance is visually recognized; and
an ensemble processing unit
configured to transmit a performance sound signal of performance sound, which is collected by a microphone of the signal processing device in response to the output signal, to the remote signal processing device via the network, and
configured to receive a performance sound signal of performance sound, which is collected by a microphone of the remote signal processing device in response to the output signal, from the remote signal processing device via the network, to output the performance sound, which is collected by the microphone of the remote signal processing device in response to the output signal, from a speaker of the signal processing device.
