Abstract: Vocal musical performances may be captured and, in some cases or embodiments, pitch-corrected and/or processed in accord with a user selectable vocal effects schedule for mixing and rendering with backing tracks in ways that create compelling user experiences. In some cases, the vocal performances of individual users are captured on mobile devices in the context of a karaoke-style presentation of lyrics in correspondence with audible renderings of a backing track. Such performances can be pitch-corrected in real-time at the mobile device in accord with pitch correction settings. Vocal effects schedules may also be selectively applied to such performances. In these ways, even amateur user/performers with imperfect pitch are encouraged to take a shot at “stardom” and/or take part in a game play, social network or vocal achievement application architecture that facilitates musical collaboration on a global scale and/or, in some cases or embodiments, to initiate revenue generating in-application transactions.

Abstract: A radio transmitter having a RF signal source. A splitter receives an input signal from the signal source and divides that input signal into two output signals. These output signals are fed into two phase shifters. A phase control signal is applied to each phase shifter so that the vector sum of the output signals represents the desired amplitude and phase of the desired transmitted signal. The outputs of both phase shifters are both frequency multiplied and amplified before recombining to form the transmitter output signal.

Abstract: When a music audio to be analyzed is to be divided into a plurality of possible pattern segments based on estimated beat positions, it is divided in a plurality of different ways according to individual division models obtained by sequentially shifting the leading or first beat position of the possible pattern segments.

For each of the sets, comparison is made between individual possible pattern segments and individual reference performance patterns. For each of the possible pattern segments of the set, at least one reference performance pattern that matches the possible pattern segment is determined. Then, at least one combination of reference performance patterns is identified for each of the sets of possible pattern segments. One optimal combination is selected from among the identified combinations.

The weighting may be based on the frequency with which it changes and the proximity of its score position to each of the other score positions represented by each of the other position signals. The same weighting factors are then applied to the tempo estimate associated with that position signal.

Abstract: A selector is provided for selecting a predetermined effect. Instruction as to whether this effect should be imparted or not is not made instantly in response to an output of this selector but made in association with instruction of start of tone generation by a key-on event signal. For example, even when a state in which an effect is selected is brought about in the course of generation of a tone without selecting an effect, this effect is not imparted to the tone which is currently being generated. Upon instruction of generation of another new tone in this state, instruction of imparting of the effect is made for the new tone so that the effect is imparted to the new tone from the start of generation of the tone. Conversely, when a state in which no effect is selected is brought about in the course of generation of a tone which is imparted with an effect, the effect is kept imparted to the tone which is currently being generated until generation of the tone is ended.

Abstract: In an electronic musical instrument for automatically a adding duet note, an apparatus, which can reduce the capacity of a memory for storing data used as a basis for selecting a duet note to be added, is disclosed. A chord depressed at a keyboard is specified by a chord specifying means, and a depressed melody note (highest note) is detected by a note detection device.
