Mixvibes Dj Community old forum

Hi, I am a new user intending to use a tablet to play prerecorded short sounds in a live theater-like scheme where I have to listen to cues and then select the right sound (song excerpt) to be played. On import these sounds obviously are assigned a BPM value. Playout then adjusts the speed to match the BPM value of the pack. On of the forum contributions mentions "play mode sound" but I cannot find this setting for my samples. How can I proceed? Overwrite all BPM values with the same value for all files?
