Abstract: An information processing apparatus includes: a storage storing a program; and a processor that performs control in accordance with the program, wherein a sound production timing is a timing of producing a sound of a note, the sound production timing being specified in a musical piece; and an early press period is between an early time point and the sound production timing, the early time point being earlier than the sound production timing by a predetermined time. In a situation that a performance action is detected within the early press period, the processor causes a sound production unit to produce a sound corresponding to the performance action at the sound production timing. In a situation that no performance action is detected within the early press period or at the sound production timing, the processor does not cause the sound production unit to produce a sound at the sound production timing.

Abstract: An electronic musical instrument includes: a memory that stores a machine-learning trained acoustic model mimicking voice of a singer and at least one processor. When a vocoder mode is on, prescribed lyric data and pitch data corresponding to a user operation of an operation element of the musical instrument are inputted to the trained acoustic model, and inferred singing voice data that infers a singing voice of the singer is synthesized on the basis of acoustic feature data output by the trained acoustic model and on the basis of instrument sound waveform data that are synthesized in accordance with the pitch data corresponding to the user operation of the operation element. When the vocoder mode is off, the inferred singing voice data is synthesized based on the acoustic feature data without using the sound waveform data.

Abstract: The present invention receives sound wave data from a sound inputted into a microphone and samples the sound wave data received using a CPU to obtain sampled data as a digitized tone data, which is then stored in a sampling memory. The CPU performs auto-play of a sound using the digitized tone data sampled by the sampling and stored in the sampling memory. Thus, a result of the sampling is automatically provided to the user after the sampling takes place and the user can intuitively understand what can be done through sampling.
