Latency with external controller

I'm experiencing a very very noticeable latency with my N.I Maschine controller when it is bound to an UI object in m4l. It doesn't happen when the Maschine is bound to a Live UI object out of m4l. This is particulary huge when it involves giving info back to my controller (i.e i have a live.toggle bound to a pad, when the toggle goes off in m4l, the pad is updated nearly 1 second after).
