understood, but Csound::GetOutputBufferSize() returns 0 after
CppSound::perform() and Csound::PerformBuffer() just hangs.  code attached

// test app for CppSound
#include "CppSound.hpp"

int main(int argc, char* argv[])
{
    // cppsound object
    CppSound* cpps = new CppSound();

    // create score
    cpps->addScoreLine("f 111 0 4096 10 1");
    cpps->addScoreLine("i 100 0 1.0 20000 220 111");
    cpps->addScoreLine("i 100 0 -1");

    // create orchestra
    cpps->setOrchestra("instr 100\na1 oscil p4,p5,p6\nout a1\nendin");

    // create csound command with temp orc and score
    cpps->setCommand("csound -RWdfo test.wav ./tempk.orc ./tempk.sco");

    // export performance
    cpps->exportForPerformance();

    // perform?
    cpps->perform();
    // cpps->PerformBuffer() hangs
    // cpps->Perform() hangs

    // size check (returns a zero size)
    printf("%ld\n",cpps->GetOutputBufferSize());

    // cleanup
    delete cpps;
    return 0;
