I'm working on a really simple MIDI note visualisation engine, and have hit a 
frustrating problem. I've setup a composition to to make a red square appear 
whenever a note in the range C1 > B1 is pressed. So, I have an Iterator with 12 
iterations, each iteration corresponding to 1 note. I'm attempting to handle 
multiple retriggers of the same note within a short period by nesting another 
Iterator inside the first. The problem is, the same setup that works for a 
single key trigger (the inner Iterator) does not work properly when nested. It 
works perfectly when it's not though. I can't work out what the problem is.

I'd be really grateful if someone could have a look at the attached QTZ and 
tell me if it's conceptually flawed, or if I've stumbled on a bug.

Oh, I'm using MacOS 10.6.1.

Thanks a lot guys!
