Hi Carlo,

I stumbled across this while trying to figure out the rvoice mixer rendering data flow: FluidSynth allocates 8192 * sizeof(fluid_real_t) of memory for each output buffer, so for a normal stereo setup with reverb and chorus and double-precision floats that's 256k of memory. The size is hard-coded in fluid_rvoice_mixer.h: #define FLUID_MIXER_MAX_BUFFERS_DEFAULT (8192/FLUID_BUFSIZE) So if you know how many blocks you render at any one time, you can probably change the 8192 to something *much* smaller (maybe even to FLUID_BUFSIZE), reducing the memory footprint of FluidSynth quite a bit. Cheers, Marcus
