Could you elaborate on this, i e specify constraints for Devices and 
Modifiers, if any? E g, would UCM allow for three active Devices and 
four active Modifiers, all resulting in seven independent PCM streams 
running concurrently? Or are there constraints in that e g all Devices 
and/or Modifiers must share the same PCM stream?
