Method for controlling audio signal processing device, audio signal processing device, and storage medium

An audio signal processing device comprising:

• a plurality of mixing buses, each of the mixing buses mixing audio signals processed in a plurality of channels:
• an acceptor circuitry configured to accept a switching instruction to switch a function of the mixing buses;
• and
• a control circuitry configured to switch operation mode of one or a plurality of switch mixing buses among the plurality of mixing buses between a first mode and a second mode in accordance with the switching instruction,
• wherein, in the first mode, the audio signal processing device controls ON/OFF of signal transmission from each of the channels to the switch mixing bus in accordance with settings of ON/OFF of signal transmission from the each channel to the switch mixing bus, and
• wherein in the second mode, the audio signal processing device controls ON/OFF of signal transmission from each of the channels to the switch mixing bus in accordance with manipulation of cue controls respectively provided to correspond to any of the channels.
