[Matti Viljamaa]

Ok this is fixed.
I don’t know how though, the code given given earlier works, but it seemed that somehow I had switched two of the lines to (which are in the wrong order)

>> patch = pdengine->openPatch("testpatches/sine.pd", ".”);
>> pdengine->init (/*NInChannels()*/ 0, 2, GetSampleRate());
