Chase programming
Chase programming is a type of programming of a drum computer in which the user has a button with an illuminated display for each beat of a bar . These buttons are usually arranged in a row. When the device has started, it shows each beat by briefly flashing the lamp associated with the beat, hence the name "running light".
The buttons are used to enter the rhythm program. This is a scheme in which beats and rhythm sounds are assigned to one another as required. The illuminated displays represent this assignment, namely by means of continuous light, so that it can be distinguished from the aforementioned flashing.
In a simple case, the basic beat is limited to sixteenth notes and the time signature to 4/4, so that the device requires 16 buttons and lamps. Many devices have this button and lamp arrangement, but also use them for their additional options, including for displaying other time types. With a 3/4 clock, for example, only 12 of the 16 buttons and lamps are used.
The concept of chase programming can be found in a similar way with step sequencers and groove boxes .
