I bought Garritan Steinway basic and installed it as an audio unit in Garageband 09. Steinway shows in the list of instruments. I am however not able to hear any sound. I didnt do anything fancy. Dont have knowledge for that. In softwareinstrument/edit/SoundGenerator I simply chose Steinway. It shows up as Browse/PianosAndKeyboards/Steinway.
What should I do in order to hear something?
