There is provided a mixing method which is executed by a mixing apparatus and
enables cascade connection without providing the mixing apparatus with any terminals
used exclusively for cascade connection. The mixing method is executed by a first
mixing apparatus including a plurality of input terminals when a second mixing
apparatus is connected in cascade to part of the input terminals of the first mixing
apparatus. At least one audio signal input to part of the plurality of input terminals
is set as at least one cascade signal supplied from the second mixing apparatus.
Arithmetic operations are performed on at least one audio signal input to at least
one input terminal other than the part of the plurality of input terminals. The
at least one cascade signal and the at least one audio signal on which the arithmetic
operations have been performed are mixed.
