Hi ajoteph,

There is a GPO2 under Garritan Studio and a GPO3 under KP2 and KP3. All three sample players are by Native Instruments. GPO4 runs under Aria by Garritan. Each successive player has become more efficient in using computer resources. KP2 and KP3 are worthwhile to get for their plug-ins. Both players are for free. GPO4 has some really good new brass instruments from Project Sam Brass. It has a basic mixer and reverb only, no other effects.

I started off with GPO2 under Garritan Studio and upgraded to KP2, KP3 and now to Aria player with GPO4. I never have had a problem. You can use KP2, KP3 and the Aria player side by side.

I don’t have Sibelius and can’t comment on it.
