Selectable functions of the mainboard DSP
The DSP on the mainboard provides selectable functions. A description of the indi-
vidual functions can be found as of
page 44
.
The functions are determined in the DSP configuration (
=ym
). In
Tab. 16
all the
possible combinations are listed, with the maximum number of voice channels. For
this the DSP chip on the mainboard has to be loaded with different firmware. Addi-
tional functions require the use of one or more DSP modules. Some of these func-
tions are subject to a licence.
