    • A vacuum tube amplification unit for use with electric instruments that allows for reduced or eliminated signal loss before the electrical signal of the instrument is amplified. The vacuum tube amplification unit includes an amplifier cartridge having an amplification circuit. The amplification cartridge is attached to and electrically connected to an instrument through a cartridge receiver. A pre-amp assembly of the amplification circuit provides a first stage of amplification, while an at least one vacuum tube provides a second stage of amplification. A power supply provides current to amplify the electrical signal of the instrument and a gain control allows for adjusting the magnitude of amplification. The amplification circuit may further include an integrated speaker, a signal converter, a transmitter, and a device terminal. Additionally, the amplifier cartridge may further include a device dock for attaching an electronic device.

    • A reproducing apparatus has three reproducing modes that are a first mode, a second mode, and a third mode. In the first mode, when a program that has been reproduction restricted is tried to be reproduced, the reproducing operation is paused and the user is asked whether he or she wants to reproduce the program. Corresponding to the user's reply, the reproducing operation is performed or prohibited. In the second mode, a program that has been reproduction restricted is prohibited from being reproduced. In the third mode, a program that has been reproduction restricted is unconditionally reproduced. When the power of the apparatus is turned on at step S31, a prompt that causes the user to select one of the first mode, the second mode, and the third mode is displayed. At step S33, a process for designating a mode is performed. Information of the designated mode is stored in a nonvolatile memory.
    • 再现装置具有作为第一模式,第二模式和第三模式的三种再现模式。 在第一模式中,当尝试再现限制的节目时,再现操作被暂停,询问用户是否要再现该节目。 对应于用户的回复,执行或禁止再现操作。 在第二模式中,禁止再现被限制的节目。 在第三模式中,无限制地再现限制了再现的节目。 当在步骤S31打开设备的电源时,显示使用户选择第一模式,第二模式和第三模式之一的提示。 在步骤S33,执行用于指定模式的处理。 指定模式的信息存储在非易失性存储器中。

    • Systems and methods for performing simple and quick real time single music note recognition algorithm based on fuzzy pattern matching are disclosed. In one aspect, the systems and methods use a 256-point FFT and fuzzy pattern identification and recognition method. The systems and methods can recognize a note as short as 0.125 seconds in a frequency range from 16 Hz to 4000 Hz, with 11.025 KHz sampling rate and 8-bit per sampling signal. The systems and methods may be used as part of a music tutor system that receives a played note, identifies the played note, and compares the played note with a reference note. An indication may be given as to whether the played note matched the reference note.

    • A method of playing music using a computing system in which MIDI events are synchronized with samples is disclosed. A sequence of MIDI events is provided. At least one of the MIDI events includes delta time parameter data, and the MIDI events are provided to a digital signal processing resource. Audio stream events are processed, and one or more of the audio stream events has associated therewith audio sample data, and the audio sample data is provided to the digital signal processing resource; the audio sample data is not provided from a MIDI sound bank. A first MIDI event is provided that is configured to include delta time parameter data associated with the intended playback timing of at least one audio stream event. The audio stream event is rhythmically synchronized with the sequence of MIDI events using the first MIDI event. The first MIDI event may be an NRPN MIDI command. The audio sample data may be decoded before the audio sample data is provided to the digital signal processing resource, and as a first step the audio sample data may be encoded in a compressed audio format. The digital signal processing resource may consist of a first section associated with the MIDI events and a second section associated with the audio stream data. The audio stream data may be preloaded using a second MIDI event associated with an earlier point in time in the music than the first MIDI event. The second MIDI event may be processed in response to user input.
