weird tempo behavior in midi
In the score attached I tried to set the tempo to 50 bpm.
When I export to midi and import to garageband where I can have a tempo track, the tempo oscillates between 50 and 80. Any idea what is going on? It appears to be related to the use of layout breaks.
I've included a screen shot of the garage band behavior 
Thanks

Those aren't just layout breaks, they are section breaks which come with a configurable 3s pause. Since MIDI doesn't have a "pause" concept, this is handled by inserting a tempo change and rest for the configured duration, then the score's tempo is restored for the remainder of the playback.
And indeed you see here one empty measure at 80qpm equals
4beats * 60secs / 80qpm = 3 secondsIf you change the pause value for the section break, you'll see the tempo used changed to compensate for that.
