摘要： A breath controller for musical instruments includes a mouth piece for blowing the air into an air chamber. Blowing the air makes an air pressure increase in the air chamber, thus an elastic member is displaced corresponding to the air pressure. At the same time, the displacement of a reflection surface changes an amount of light to reflect an emitted light from a light-emitting element to a light-receiving element. The light-receiving element then controls a signal corresponding to the amount of light, thus making the signal change to a musical tone signal.
摘要翻译：用于乐器的呼吸控制器包括用于将空气吹入空气室的口部件。吹空气使得空气室中的空气压力增加，因此弹性构件相应于空气压力而移动。同时，反射面的位移改变了光的量，以将发射的光从发光元件反射到光接收元件。然后，光接收元件控制与光量对应的信号，从而使信号变为乐音信号。

摘要： A first amplifier stage receives electrical signals generated by a musical instrument and provides an output signal. A second amplifier stage is driven by the output signal from the first amplifier stage as switch selectively connects an attenuator to the first amplifier stage to attenuate the output signal thereof and selectively connects a gain modifying circuit to the first stage. In a first mode, the attenuator is connected to the first amplifier stage and the gain modifying circuit is disconnected from the first amplifier stage. As a result, an output signal from the first amplifier stage has a level which drives the second amplifier stage to provide a substantially linear output signal therefrom. In a second mode, the attenuator is disconnected from the first amplifier stage and the gain modifying circuit is connected to the first amplifier stage. As a result, an output signal from the first amplifier stage has a level which will overdrive the second amplifier stage to provide a non-linear saturated signal therefrom having a first desired amount of increased harmonic saturation.
摘要翻译：第一放大器级接收由乐器产生的电信号并提供输出信号。当开关选择性地将衰减器连接到第一放大器级以衰减其输出信号并选择性地将增益修改电路连接到第一级时，第二放大器级由来自第一放大器级的输出信号驱动。在第一模式中，衰减器连接到第一放大器级，并且增益修改电路与第一放大级分离。结果，来自第一放大器级的输出信号具有驱动第二放大级以从其提供基本上线性的输出信号的电平。在第二模式中，衰减器与第一放大器级断开，并且增益修改电路连接到第一放大器级。结果，来自第一放大器级的输出信号具有将使第二放大器级过驱动从而提供具有第一期望量的增加的谐波饱和的非线性饱和信号的电平。

摘要： A variable control device accessory for a music synthesizer having a horizontally disposed keyboard. The device is positioned in front of the keyboard. It has a plurality of movable bars, at least of one of which is capable of being pivotally and slidably moved by the wrist of a player while all the others are only slidable. The bars modulate selected light beams focussed on light responsive mechanisms to produce variably dependent analog signals as inputs to the music synthesizer.

摘要： A two hand operated instrument, for controlling electronic music synthesizers, video games and computers, capable of producing two independent control voltages, in addition to the signals produced by keyboards held in each hand, such additional control voltages actuated by rotating and telescoping the concentric tubes with respect to each other. In musical applications, the finger operated voltage signals may be used to select notes and the twist and telescope signals to control musical parameters, such as volume, pitch, timbre, pulse, width, spatial location, etc.

摘要： A player piano recording system has photosensor flags secured to the undersides of the piano keys, vertical movement of which is detected by horizontally adjustable photosensors to produce "key played" and key velocity signals which supplied to a microprocessor for deriving expression signals for recording on magnetic tape. The microprocessor provides output expression values and key play information. According to the invention, the expression values are a direct function of key velocity and key play information and switch selected boost (an enhanced initial frame expression for overcoming solenoid inertia) and add (for trill) values. Key play data is dependent upon key play inputs and the frame extension switch value. The unique structure of the key flag permits horizontal adjustment of the photosensors for vertical misalignments etc. of the piano keys. Player piano tapes prepared by use of the invention may be used directly to control player pianos or as master tapes for the production of commercial cassette tapes for consumer use with commercially available tape controlled player pianos.
摘要翻译：玩家钢琴记录系统具有固定在钢琴键的下侧的光电传感器标记，其垂直移动由水平可调节的光电传感器检测，以产生“键盘播放”，并将提供给微处理器的键速度信号用于导出用于在磁性上记录的表情信号胶带。微处理器提供输出表达式值和键播放信息。根据本发明，表达值是键速度和键盘播放信息的直接函数，并且切换所选择的升压（用于克服电磁铁惯性的增强的初始帧表达式）并添加（用于颤振）值。键播放数据取决于键播放输入和帧扩展开关值。键标志的独特结构允许光电传感器的水平调整用于钢琴键的垂直未对准等。使用本发明制作的演奏者钢琴磁带可以直接用于控制演奏者钢琴或作为用于生产用于消费者使用的商用盒式磁带的主磁带，其中市售的磁带控制的演奏者钢琴。
