Abstract: A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.

Abstract: An automatic player piano has a released key velocity estimator for modifying the constant released key velocity of a piece of music data information to a target released key velocity; a memory stores relation between the target key velocity estimator and other key-touch factors such as a final hammer velocity and a time interval between an impact timing and a key release timing, the released key velocity estimator supplies the key-touch factors to the memory so as to read out the target key velocity estimator, and modifies the piece of music data information so as to indicate the target released key velocity.

Abstract: An ideal automatic player piano is assumed to reproduce an original performance from fundamental data representative of a fundamental forward key trajectory and a backward key trajectory; however, if an actual automatic player piano reproduces a forward key trajectory and a backward key trajectory on the basis of the fundamental data, the forward key trajectory and the backward key trajectory do not faithfully reproduce the original key motions; for this reason, the actual automatic player piano learns first offset time at the end position and second offset time at an intermediate position between the end position and the rest position so as to determine a virtual forward key trajectory and a virtual backward key trajectory, and further learns first dead time around the rest position and second dead time around the rest position so as to exactly determining first starting time at the rest position and a second starting time at the end position, thereby moving keys along composite forward/backward trajectories

A plurality of optical emitter/sensors are mounted on the pedal support assembly of a piano, and a plurality of corresponding optical reflectors are mounted on the moving connecting rods associated with piano pedals on the piano. Output voltage signals from the optical emitter sensors, which vary according to pedal movement, are monitored and used to generate and record pedal position values. The recorded pedal position values are then used to recreate the original pedal expression of the piano performance by generation of pulse width modulation signals which are used to drive solenoids associated with piano pedals.

Abstract: A sequence generator for a polyphonic tone synthesizer in which a repetitive sequence of musical notes or chords are generated automatically. During a Code mode of operation, each key operated on the keyboard causes an associated data word identifying the specific key by keyboard, octave and note to be stored in a memory. Time data as to the relative time the note is to go on and go off is also stored as part of the data word. During a Play mode of operation, the data words are read out of memory in the sequence in which they were generated. The words are decoded and the time data compared with a real time clock to provide signals to the output of the keyboard which duplicate the signals from the corresponding keys. The time duration of these signals is controlled by the time on and time off data to duplicate the required time that the respective notes are to be played.
