app_sysex_event is not called

[Dymaxion00]

I'm trying to implement a sysex ID request handler, as I've got a piece of hardware that seems to need it to recognize the device. However, the app_sysex_event method doesn't seem to actually get called when I send it 0xF07E7F0601F7. I've attached a minimal code snippet that reproduces the problem. This should light pad 1 any time any sysex message comes in, but it does not light.
