    • An improved keyboard (115) for a musical instrument includes a plurality of keys arranged in a side-by-side order, all lying in a common plane. Different embodiments of the invention have a varying number of keys per octave, from as small as 12 keys per octave to as high as 90-120 keys per octave. In those embodiments of the invention in which the number of keys per octave results in a key whose width is too narrow to be uniquely depressed by an operator's finger, associated apparatus (403) determines from a plurality of keys (110-140, 180-220) which have been depressed, a particular tone to be produced. The keyboard may be associated with apparatus (401) to distinguish one set of keys from other sets of keys, which apparatus can include a selectively energizable light source (38) associated with each different key or other equivalent apparatus.
    • 用于乐器的改进的键盘(115)包括以并排顺序布置的多个键,全部位于公共平面中。 本发明的不同实施例具有每倍频程的不同数量的键,从每个八度至12个键到每个八度音程高达90-120个键。 在本发明的这些实施例中,每个八度音阶的键的数量导致其宽度太窄而不能被操作者的手指唯一地按下的键,相关联的装置(403)从多个键(110-140,180- 220),其被抑制,要产生特定的音调。 键盘可以与装置(401)相关联,以将一组键与其他键组区分开,该装置可以包括与每个不同键或其它等效装置相关联的选择性激励光源(38)。

    • An electronic musical instrument comprises a keyboard (11) for generating tone data or key codes each representative of a tone to be generated and a tone generating circuit (14) having a plurality of tone generating channels (#1 to #N). The electronic musical instrument also comprises a RAM (18) having a plurality of storing positions for storing the key codes each of which is assigned under the control of a central processing unit (CPU (17)) to a respective one of the tone generating channels to thereby generate a tone determined by the assigned key code. When a key is newly depressed on the keyboard - (11), each of the key codes stored in the RAM (18) is read therefrom and supplied to an envelope generator (19) which in turn generates data (EGL) representative of an amplitude of each of the envelopes given to the tones. The key codes read from the RAM (18) are also supplied to a ROM (22) to read therefrom weighting data. The CPU (17) modifies each of the envelope amplitude data (EGL) based on a respective one of the weighting data, and selects one of the key codes stored in the RAM (18) in accordance with the modified envelope data. Then, the CPU (17) replaces the selected key code in the RAM (18) by the key code generated in response to the new depression of the key.
    • 一种电子乐器包括用于产生各自表示要产生的乐音的乐音数据或键码和具有多个乐音产生通道(#1至#N)的乐音产生电路(14)的键盘(11)。 该电子乐器还包括具有多个存储位置的RAM(18),该存储位置用于存储在中央处理单元(CPU(17))的控制下分配给每个乐音产生通道 从而生成由所分配的键码确定的音调。 当在键盘上新按下一个键时(11),存储在RAM(18)中的每个键码被从中读出并提供给包络发生器(19),该包络发生器又产生代表幅度的数据(EGL) 给每个音调赋予的信封。 从RAM(18)读取的键码也被提供给ROM(22)以读取加权数据。 CPU(17)根据加权数据中相应的一个修改每个包络幅度数据(EGL),并根据修改的包络数据选择存储在RAM(18)中的一个密钥代码。 然后,CPU(17)用响应于新按下的键所产生的键码来替换RAM(18)中所选择的键码。
