摘要： A signal mapping system maps sensor signals into control signals that control the operation of a music synthesizer. A "one to many" mapping technique is used, allowing at least some of the sensor signals to each be mapped into numerous music synthesizer control signals. Physical gestures by a user are mapped into a large set of music synthesizer control signals, some of which continuously vary in value as the user moves through the gestures. Signal mapping functions are used to map the sensor signals into note number and velocity values for at least one voice to be generated by the music synthesizer. The note number and velocity values are sent to the music synthesizer as note-on events when predefined note-on and note-off trigger conditions, defined with respect to specified ones of the sensor signals, are satisfied. Other ones of the signal mapping functions are used to generate asynchronous control signals that are sent to the music synthesizer independent of the note-on and note-off events. A third set of signal mapping functions are used to generate the trigger signals for determining when note-on and note-off events are to be sent to the music synthesizer.

摘要翻译： 信号映射系统将传感器信号映射成控制音乐合成器的操作的控制信号。 使用“一对多”映射技术，允许至少一些传感器信号被映射成许多音乐合成器控制信号。 用户的物理手势被映射成一大组音乐合成器控制信号，其中一些音乐合成器控制信号随着用户移动手势而不断变化。 信号映射功能用于将传感器信号映射到由音乐合成器生成的至少一个语音的音符数量和速度值。 音符编号和速度值作为音符事件发送到音乐合成器，当预定义的关于指定的传感器信号的音符开启和音符关闭触发条件得到满足时，音符编号和速度值被发送到音乐合成器。 信号映射功能中的其他功能用于产生独立于音符开关和音符关闭事件而发送到音乐合成器的异步控制信号。 第三组信号映射功能用于产生触发信号，用于确定何时将音符和音符关闭事件发送到音乐合成器。
