• Cycle Control principles:

1 Fully automatic mode: In this mode, in principle, it is required to be able to play the loop effect, in the case of possible, it is recommended to describe the end and start of a cycle by the difference of time interval;

2 Full Manual mode: In this mode, it is recommended not to do the cycle, that is, in one-dimensional direction, there is a terminal state, in order to facilitate user understanding, control;

3 Automatic and Manual mode: In this mode, in principle, it is required to maintain the unity of automatic and manual mode, that is, if the display of the automatic mode is a loop, the manual mode also provides a matching loop control, and vice versa; In general, it is recommended that this mode be used to display and control the
