I have a question concernig the sound generator in sumacc. I have sucessfully
started the Free Form sound generator whith FSWrite( -4... but i can't get it
to work with StartSound. I have tried both synchronous and async mode.

This is selected parts of the code.

# define FFMODE 0
typedef FFSynthRec * FFSynthPtr;
unsigned char *waves;
FFSynthPtr wave_ptr;
int the_time;
...
wave_ptr = (FFSynthPtr) NewPtr(100000);
wave_ptr->mode = FFMODE;
waves = wave_ptr->waveBytes;
...
wave_ptr->count = FixRatio(the_item+1-SOUND90, 1);
wave_ptr->waveBytes[0] = 0;
wave_ptr->waveBytes[1] =     ...

/* This works fine */
FSWrite( -4, &the_time, wave_ptr);

/* Those two do not */
StartSound(wave_ptr, the_time, (ProcPtr) -1);
StartSound(wave_ptr, the_time, (ProcPtr) 0);

What am i doing wrong ?
