AGI: Fix Crash with Apple][ Instruments
|Reported by:||SF/mthreepwood||Owned by:||SF/buddha_|
When the instrument data for Apple][ AGI games is not present, and the engine tries to play a MIDI sound, the game crashes with a failed assertion in common/array.h, line 94. This patch disables midi sound when the instruments haven't been found which fixes the crash.
