In a synthesizer, the highest note number is set from the allowed Oct width and the lowest note number of a sound production part in a setting table, and if the note number of an Arp note memoryis not between the lowest note number and the highest note number, the note number of one octave unit is added to or subtracted from the note number of the Arp note memory. Consequently, the note number of the Arp note memoryis corrected to the pitch range between the lowest note number and the highest note number, and thus can be corrected to the sound production pitch range of the timbre of the sound production part, and arpeggios can be outputted using sounds that are more appropriate for an instrument of said timbre.

Arpeggiator, recording medium and method of making arpeggio

[Problem] To provide an arpeggiator capable of creating a rich arpeggio performance that includes multiple pieces of performance information, and a program equipped with a function therefor. [Solution] When the key press mode for a sounding part is a chord, a synthesizeracquires all note numbers from a remain table for the sounding part in a setting tableand stores all the note numbers in an Arp note memory. This allows all the notes corresponding to the note numbers set in the remain table to be concurrently generated at the sounding time set in an Arp pattern. That is, an expressive arpeggio based on a chord made up of all the notes corresponding to the note numbers set in the remain table can be produced.

[Problem] To provide an arpeggiator enabling musically natural arpeggio playing to be achieved, and a program comprising a function therefor. [Solution] In the present invention, a synthesizerresets the number of octaves in an octave counter memoryto zero at the beginning of each bar when an octave reset function is on. Due to this configuration, sounds generated at the beginning of each bar, that is, when the step count is 0, all have the same note number. Consequently, a sound generation timing-based cycle of an arpeggio pattern of each bar can be synchronized with a pitch variation-based cycle, making it possible to give a listener the impression that a consistent phrase is being played.

A musical tone signal processing apparatus configured to extract musical tone signals that are signal processed for a plurality of localizations. Such an apparatus may be configured to carry out signal processing for signals that have been extracted by first retrieving processing (S) and/or second retrieving processing (S). The first retrieving processing (S) and the second retrieving processing (S) extracts a musical tone signal (e.g., the left channel signal and the right channel signal) that satisfies each of the conditions that have been set (e.g., frequency, localization, and maximum level) as the extraction signal. Accordingly, the extraction signal can be extracted to allow the musical tone signal processing apparatus to signal process the extraction signal for each of the plurality of conditions.

Musical tone signal-processing apparatus

A musical tone signal processing apparatus configured to freely expand or contract an acoustic image. A setting means may set a second reference localization, a first function that stipulates expansion of the boundary of one end of a direction range, and a second function that stipulates expansion of the boundary of an other end of said direction range. In addition, an output direction indicated by localization information of an extraction signal that exists in the direction range in which the conditions have been set in this manner is shifted by an acoustic image scaling means. The acoustic image in said direction range is expanded or contracted accordingly. In other words, the acoustic image formed by the extraction signal is expanded or contracted by shifting the output direction for each extraction signal extracted from within the direction range.

A user interface apparatus for displaying areas having vocal or instrumental unit signals that are included in an input musical tone signal. Display locations, for display on a display screen that has a localization-frequency plane, are calculated for the input musical tone signal based on localization information of each frequency band. Then, the primary level distributions, in which the levels of the frequency band corresponding to each display location are expanded and obtained using a specified distribution in each of the frequency bands, is calculated. The secondary level distribution is calculated in this manner by aggregating the frequency bands for each respective display location. Said secondary level distribution is displayed in three dimensions (the localization axis, the frequency axis, and the level axis) and viewed from the level axis direction. Therefore, the areas, in which the vocal or instrumental units exist in a grouped state, can be easily identified.
