How would you power each structure? What would the distance from the structure to the controlling computer be? What types of sounds are you trying to make? Are you going to need a lot of flash to store the sounds?
I would make five identical structures and control them with a Zigbee radio (like
the MaxStream XBee). All you would need to do is to plug in the structure. The control PC would then communicate point-to-point with each structure.
I have some application information and some simple examples of wireless control

The XBee also has digital I/O so for simple control a uC would not be needed.
Check the MaxStream XBee datasheet.
