@diego > Please don't type all IN CAPS, it's considered yelling... and the bold doesn't help either.
Searching (using the on-screen keyboard) requires that your tracks are processed via rekordbox. Your search will find results in most fields (although not comments, if I recall).
The only time the jog will illuminate red is when linked with a Pioneer DJM900 or DJM2000 - the red jog indicates "on air" status.
