I play a weekly gig at a club that purchased the TTM 57 a few months back and like a lot of the new functions, especially the ease with which I can set and trigger cue points.

Lately, I've noticed that the two of the "soft" buttons (or whatever it is the buttons labeled B1 through B6 are called) keep sticking. That is, the buttons don't respond accurately, no matter what touch I use when I depress them (e.g., hard, slowly, from an angle, etc.)-- sometimes they respond, but most of the time they don't. This is really aggravating.

As far as I can tell, the mixer hasn't suffered any unusual abuse (there's no stickiness from drinks spilled on it, for example), just normal wear and tear (dust, grime, inept DJs).

Two questions:

1. Is there a way to fix the buttons so that they respond normally again?

2. Is there a way to prevent this from happening to the other buttons?
