	Hello, not sure if I'm at the appropriate place but can anyone tell me why I don't get any sound with this program: #include "H/csound.h" #include uintptr_t csThread(void clientData); typedef struct { int result; //result of csoundCompile() CSOUND csound; //instane of Csound int PERF_STATUS; //tells us if Csound is running }userData; //------------------------------------------------------------ int main(int argc, char argv[]) { int userInput=200; void ThreadID; userData* ud; ud = (userData )malloc(sizeof(userData)); MYFLT pvalue; ud->csound=csoundCreate(NULL); csoundInitialize(&argc, &argv, 0); ud->result=csoundCompile(ud->csound,argc,argv); if(!ud->result) { ud->PERF_STATUS=1; ThreadID = csoundCreateThread(csThread, (void)ud); } else { printf("csoundCompiled returned an error"); return 0; } printf("\nEnter a pitch in Hz(0 to Exit) and type return\n"); while(userInput!=0) { if(csoundGetChannelPtr(ud->csound, &pvalue, "pitch", CSOUND_INPUT_CHANNEL \| CSOUND_CONTROL_CHANNEL)==0); pvalue = (MYFLT)userInput; scanf("%d", &userInput); printf("Okay, %d\n",userInput); } ud->PERF_STATUS=0; return ud->result; } //------------------------------------------------------------- //definition of our performance thread function uintptr_t csThread(void data) { userData udata = (userData*)data; if(!udata->result) { while((csoundPerformKsmps(udata->csound) == 0) &&(udata->PERF_STATUS==1)); csoundDestroy(udata->csound); } udata->PERF_STATUS = 0; return 1; } //-------------------------------------------------------------------------------------------- ... I load this instrument file and get no sound: instr 1 kval chnget "pitch" a1 oscil 10000, kval, 1 out a1 endin _________________________________________________________________ http://clk.atdmt.com/UKM/go/195013117/direct/01/ We want to hear all your funny, exciting and crazy Hotmail stories.
