create an output audio signal

[pansoul]

Hello
with the SDK V2 i succeed to create an output signal but now with v3 version i have some difficulties
i tried this

for (kk = 0;kk < 128;kk++){
pMultiLooper->SetEvtArrayData(pMultiLooper->paudioout,kk,sin(2*3.1415*kk/128));
}

but it doesn't work (no output sound)
am i using the good fonction ?
thanks

yep, it's the good function...

maybe you forget to set the paudioout event size, the InitModule is a good place for that :

Code: Select all

	
void InitModule (void* pModule, TMasterInfo* pMasterInfo, TModuleInfo* pModuleInfo) {

	TMultiLooper* pMultiLooper = ((TMultiLooper*)pModule);

	// remember, it's up to us to initialise the pMasterInfo poimnter herited from TUserModule
	pMultiLooper->SetMasterInfo(pMasterInfo);
	
	pMultiLooper->SetEvtSize( pMultiLooper->paudioout, pMultiLooper->GetBlocSize() );	

}

and you should clean your code

Code: Select all

	
	// local variable used in for loop
	int i;
	int blocksize = pMultiLooper->GetBlocSize();

	for &#40;i = 0; i < blocksize; i++&#41;&#123;

		pMultiLooper->SetEvtArrayData&#40;pMultiLooper->paudioout, i,sin&#40;2*3.1415*i/128&#41;&#41;;
	&#125;

and ideally put out all constant operations from the for loop

Code: Select all

	
	// local variable used in for loop
	int i;
	int blocksize = pMultiLooper->GetBlocSize();
	float sampleoperator = 2*3.1415/(float)blocksize ;

	for &#40;i = 0; i < blocksize; i++&#41;&#123;

		pMultiLooper->SetEvtArrayData&#40;pMultiLooper->paudioout1, i,sin&#40;sampleoperator *i&#41;&#41;;
	&#125;
