TODOs

• Loading of carbon/cocoa audio units' gui

XCode Sample Project >

The sample code which can load a host Audio Unit borrows heavily from PlaySequence sample code / but allows you to specify Kontakt Player rather than just dls files. ./PlaySequence /yourpath/pyau/Midi/1.mid -b /yourpath/gitWorkspace/pyau/gls.dls -p -f "/yourpath/pyau/test.wav" lpcm 44100
