SYNOPSIS

10       #include <allegro.h>

13       void reserve_voices(int digi_voices, int midi_voices);

DESCRIPTION

16       Call this function to specify the number of voices that are to be  used
17       by  the  digital and MIDI sound drivers respectively. This must be done
18       _before_ calling install_sound(). If you reserve too many voices,  sub‐
19       sequent  calls to install_sound() will fail. How many voices are avail‐
20       able depends on the driver, and in some cases  you  will  actually  get
21       more  than  you reserve (eg. the FM synth drivers will always provide 9
22       voices on an OPL2 and 18 on an OPL3, and the  SB  digital  driver  will
23       round  the number of voices up to the nearest power of two). Pass nega‐
24       tive values to restore the default settings. You should be  aware  that
25       the  sound  quality is usually inversely related to how many voices you
26       use, so don't reserve any more than you really need.
