Quick and probably easy question that I just can't seem to figure out.

I am running the Sibelius 5.2 update and Virtual Drumline 2 on my MacBook Pro. I'm using an M-Audio KeyRig 25 2-octave MIDI controller. I turned on the IAC Driver, and loaded the samples I wanted, but I can't get them to play back. In the VDL2 manual, it tells you how to set the MIDI channels, but it's not the configuration that Sibelius 5 has. You set the IAC driver for the instruments in the mixer window, but it won't let you select which MIDI channel that you want it to play from. What am I missing?

Sibelius 5.2 will host any VST or AU program, like Kontakt Player 2. You don't need to run them externally.

Got it. Thanks.
