Abstract

The invention provides a musical keyboard test system which comprises a test device, a control device and an output device, wherein the test device is arranged on an adjusting or sounding component of a musical keyboard. The adjusting or sounding component comprises musical note keys, buttons and a potentiometer, the control device comprises a test command transmitting module and a data receiving module which are connected with the test device through signals, the control device is used for transmitting a test instruction to the test device and receiving a test signal fed back by the test device, an output module is connected with the test device through signals, and a test result is outputted according to the test signal fed back. Specific press-down and lift-up information is transmitted to the control device when a certain musical note key or button in the musical keyboard is pressed down and lifted up, the control device judges whether the musical keyboard is abnormal or not according to the information, requirements on technical knowledge of testers are lowered, test speed and efficiency are increased, and quick test on a flow production line in batch production is facilitated.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to a musical keyboard testing system. Background technique [0002] A MIDI keyboard is an electronic keyboard that can output midi signals. The general test method for a MIDI keyboard is to check whether each function button is normal according to the test manual. But in some cases, the button only changes an internal state, and it is impossible to confirm whether the button is working normally from the outside. Only after some combined operations can it be judged whether the button is working normally. [0003] Some digital control potentiometers are also common controls on MIDI keyboards. When testing, it is not only necessary to detect whether the potentiometer is in motion, but also to check whether the potentiometer can slide to the specified position during the action process, such as the maximum range, minimum value range, etc. Testers not only need to understand how to us...
