摘要： A transposing and intramanual coupling control circuit for an electronic keyboard instrument in which the status of the keys are scanned in groups by a group counter, each group corresponding to the twelve notes of an octave. The keys in each group provide status signals on a corresponding number of time-shared output lines as each group is scanned. If any key in a particular group has changed status, the scanning of the groups is interrupted and the individual keys in the particular group are scanned by a note counter to determine which keys have changed status. If a key has been depressed, the note number and octave number in the respective counters are stored in an assignment memory for assignment to a tone generator. Transposition is provided by shifting the phasing between the key scanning by the note counter relative to the output lines by a predetermined set amount at the start of each group scanning step. Depending on the set amount, which can be changed at the group scanning rate, a transposed note number is stored along with the octave number in the assignment memory in response to depression of a given key in a group. If the transposed note number associated with a particular key is in the next octave, the octave number from the group counter is adjusted by one as stored in the assignment memory.

摘要翻译： 一种用于电子键盘乐器的转置和内部耦合控制电路，其中键的状态由组计数器分组扫描，每组对应于八度音阶的十二个音符。 每个组中的键在每个组被扫描时在相应数量的时间共享输出线上提供状态信号。 如果特定组中的任何键已更改状态，则组的扫描将被中断，并且特定组中的各个键将通过音符计数器进行扫描，以确定哪些键已更改状态。 如果键被按下，各个计数器中的音符号和倍频程号被存储在分配存储器中，以分配给乐音发生器。 通过在每个组扫描步骤开始时，通过音符计数器相对于输出线的键扫描之间的相位移位预定的设定量来提供置换。 根据可以组扫描速率改变的设定量，响应于按下组中给定的键，转置的音符号与八度音数一起存储在分配存储器中。 如果与特定键相关联的转置音符编号在下一个八度音阶中，则组计数器中的八度音程数按照存储在分配存储器中的方式进行调整。

摘要： A key signature actuator for a musical keyboard eases playing from music written with difficult key signatures by automatically actuating the sharps or flats in the key signatures. The keyboard has five back digitals per octave span, like the traditional keyboard, except that the back digitals are de-emphasized as landmarks by making them light gray, and musical notes are associated with movable landmarks, rather than with fixed digitals. When in written music a key signature is indicated, the landmarks are electronically shifted so that the key note of that key signature is played by a tonic digital (a fixed front digital to the immediate left of a group of two back digitals). At the same time the tonic digital is made to sound the key tone corresponding to that key signature by adjusting the overall pitch of the musical output by means of a uniform pitch changer. The number of electrically changeable landmark elements is minimized and binary coding is used to simplify the electrical connections. Apparatus for moving the landmarks mechanically is also disclosed.

摘要： The organ plays either a hexatonic scale or the diatonic scale on its front digitals. The organ has a tone transposition apparatus comprising a scale selector apparatus, a key selector apparatus and an absolute pitch changer switch. The key selector apparatus includes a hexachord key selector switch in cascade with a diatonic key selector switch. Each key selector switch is formed by two linear arrays of movable contacts sliding along two linear arrays of stationary contacts. Either of these key selector switches can be set to physically activate key signatures of written music. The key selector apparatus operates on the top octave of tones; lower tones are derived from the top octave by frequency division.
