There are three different modes of operation on the Micro BR when doing multitrack recording. Input, bounce and mastering. Take the following steps to switch modes, starting in mulitrack mode (as opposed to mp3 mode).

1. Press and hold [EXIT] then press [UTILITY]. Each time you press these buttons together it willtoggle to the next mode of operation.

You can tell what mode you are in by viewing the upper left portion of the LCD screen you will see either BOUNCE or MASTERING. If neither word is displayed you will be in the Normal or INPUT mode.
