Change of display style of an audio signal processing device due to the difference between new and old parameters

摘要

In an audio signal processing device which processes audio signals and outputs the audio signals, setting controls (118), such as filter controls (11), for setting values of parameters for the signal processing and a display (13, 24, 34) for presenting information by the presence or absence and the style of lighting of LEDs is provided, in which when scene data stored in a scene memory is loaded, the display style of the display (13, 24, 34) is made different in accordance with match/mismatch between a current set value of the parameter and the value of the parameter relating to the loaded scene data. Alternatively, the display (13, 24, 34) is made to simultaneously present the loaded value and the value at the time of the loading in different display styles.
