I asked the question on the Sibelius forum, as to if the Kontakt player included with Sibelius 3 could play the GPO sounds. Their answer is no. Sib. 3 also cannot use the Kontact player included with the GPO. From within Sib. 3 and their included Kontakt player you can only use the sound package that comes with their product. This might change in the future though. As a workaround, you could also use a product like MidiYoke to route the Sib. signal to the GPO.
