[fluid-dev] Question: why sample reference count is incremented twice ?.

[CERESA Jean-Jacques ENAC/ENAC]

 Hi,

When a voice is initialized by fluid_voice_init() function.
we can read this:
  /* Increment the reference count of the sample to prevent the
     unloading of the soundfont while this voice is playing,
     once for us and once for the rvoice. */

Why this counter needs to be incremented twice ?.
Is it not enough to increment it only one time ?

Many Tanks.
Regards
