If I do something like this, only the other sound plays :
BigInteger allNotes;
allNotes.setRange(0, 128, true);
XenSamplerSound* xsound = new XenSamplerSound(“foo1”, sfile1, allNotes, 60, 0.05, 0.2, &m_mutex);
m_synth.addSound(xsound);
xsound = new XenSamplerSound(“foo2”, sfile2, allNotes, 60, 0.05, 0.2, &m_mutex);
m_synth.addSound(xsound);
Is that how Synthesizer has been designed to work? It would be very useful for sampler type synths to allow multiple sounds to be triggered from the same note, for sound layering purposes.
