A portable electronic device with a touch screen display for photo management is disclosed. One aspect of the invention involves a computer-implemented method in which the portable electronic device displays an array of thumbnail images corresponding to a set of photographic images. The device replaces the displayed array of thumbnail images with a user-selected photographic image upon detecting a user contact with a corresponding thumbnail image in the array. The user-selected photographic image is displayed at a larger scale than the corresponding thumbnail image. The portable device displays a different photographic image in replacement of the user-selected photographic image in accordance with a scrolling gesture. The scrolling gesture comprises a substantially horizontal movement of user contact with the touch screen display.

Systems and methods for creating, modifying, interacting with and playing music are provided, particularly systems and methods employing a top-down process, where the user is provided with a musical composition that may be modified and interacted with and played and/or stored (for later play). The system preferably is provided in a handheld form factor, and a graphical display is provided to display status information, graphical representations of musical lanes or components which preferably vary in shape as musical parameters and the like are changed for particular instruments or musical components such as a microphone input or audio samples. An interactive auto-composition process preferably is utilized that employs musical rules and preferably a pseudo random number generator, which may also incorporate randomness introduced by timing of user input or the like, the user may then quickly begin creating desirable music in accordance with one or a variety of musical styles, with the user modifying the auto-composed (or previously created) musical composition, either for a real time performance and/or for storing and subsequent playback. The graphic information preferably is customizable by a user, such as by way of a companion software program, which preferably runs on a PC and is coupled to the system via an interface such as a USB port. A modified MIDI representation of music is employed, preferably, for example, in which musical rule information is embedded in MIDI pitch data, and in which sound samples may be synchronized with MIDI events in a desirable and more optimum manner. The system architecture preferably includes a microprocessor for controlling the overall system operation. A synthesizer/DSP preferably is provided in order to generate audio streams. Non-volatile memory preferably is provided for storing sound banks. Preferably removable non-volatile storage/memory is provided to store configuration files, song lists and samples, and optionally sound bank optimization or sound bank data. A codec preferably is provided for receiving microphone input and for providing audio output. A radio tuner preferably is provided so that output from the radio tuner may be mixed, for example, with auto-composed songs created by the system, which preferably includes a virtual radio mode of operation.

PROBLEM TO BE SOLVED: To provide a process for producing 4,6-diaminoresorcinol and/or its salt without causing the quality problem in the polymerization with terephthalic acid and enabling efficient recovery of by-produced (substituted) aniline. SOLUTION: 4,6-Diaminoresorcinol and/or its salt are produced by reducing a 4,6-bis(substituted)phenylazoresorcinol of the formula (R is e.g. a halogen atom or a lower alkyl; (n) is 0 or 1-5) with hydrogen in a solvent in the presence of a noble metal catalyst. In the above process, an N-basic acid is added to a raw material solution in an amount of (2/N)×(0.25-5) times mol (based on the 4,6-bis(substituted)phenylazoresorcinol), the amount of the N-basic acid in the reaction liquid after the completion of the reducing reaction is adjusted to (2/N)×(0.55-1.0) times mol (based on the azoresorcinol) and the by-produced (substituted) aniline is separated from the system.

PURPOSE:To easily give diverse timbre variation to a musical sound waveform signal of high quality at low cost. CONSTITUTION:Waveforms consisting of plural cycles among all waveforms from the start to the end of sound generation are stored in a memory 17, and they are read out and inputted to a digital filter 14. Filter characteristics are set with filter characteristic parameters which vary with the time from the start to the end of the sound generation of a musical sound and the timbre of the waveform signal of high quality read out of the memory 17 is varied with the time and controlled with diverse characteristics according to the parameters. The parameters can be improved in precision by being determined according to the deviation in waveform spectrum between the memory read waveform and a desired waveform when the envelope amplitude level is made nearly constant. The whole waveform section is divided into plural frames and level parameters are generated corresponding to the respective frames; and the level of the waveform signal is controlled with them and then the precision of timbre variation by filtering is improved.

Tone color data are stored in a tone generator storage region of a RAM (4) The tone generator data storage region (4) is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region (4), and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region (4), a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region (4), the tone color data are read out from a storage medium (100) storing the selected tone color data, and transferred to and stored in the tone generator data storage region (4), while generating a musical tone based on other tone color data similar to the selected tone color data

Method and apparatus for generating musical tones, processing and reproducing music data using storage means

A pitch synchronizing signal (PS) synchronized with the pitch of a digital tone signal to be filtered is generated by a pitch synchronizing signal generation circuit (110). A digital filter circuit (111) which receives the digital tone signal and imparts it with a desired tone color by subjecting it to a proper filter operation executes this filter operation with a sampling period synchronized with the pitch synchronizing signal. A moving formant thereby is realized which is suitable for control of a tone. A pitch synchronization output circuit for sampling and outputting the output of the digital filter circuit in accordance with the pitch synchronizing signal may be provided and this will prevent occurrence of a sampling noise. A switching circuit is provided for enabling switching order of the digital filter circuit between an even number and an odd number. By this switching of order, a desired filter characteristic can be realized with high fidelity. The filter coefficient may be used commonly for two orders positioned at symmetrical positions. Filter coefficients which do not undergo timewise change and those which undergo timewise change may be selectively supplied in separate channels.
