Not every time i power up megadrum with USB, my macbook with logic 9 doesnt receive any midi message.
The Vu meter are flat, and the midi led doesn't blink.
Only the Hihat pedal work (only on megadrum display)
But (i realize this because i was angry and i started to hit hard and fast my pads

If i reload config ( i set "autoload config" yes) all works fine.

but i can play anyway!
