No. It is a place holder or mute on the track it's assigned to.

In earlier years when there wasn't thousands of hours of recorded audio for RealTracks or thousands of RealTracks, it was easy to identify a song created using BIAB because of the limited amount of recorded data, it was common to hear many songs using the same riffs by different users. It was also quite common to have to edit a RealTrack when using the Bar Settings (F5) to mute and unmute tracks during the user arrangement process because of abrupt endings, transitions and intros. Somewhere along the way, PG developers created RT 1152 for the algorithm to read and account for a transition or mute and select RealTrack data accordingly and add fade-outs, fade-ins, cross-fades, and different audio recorded for endings and intros so that using RT 1152 eliminated the necessity to edit these transitions. RT 1152 allowed BIAB to have smooth transitions.

Another feature that takes advantage of programmed silence of RT 1152 is the RealTrack Medley Maker. The RealTrack Medley Maker functions as a sub-mixer for each of the 24 Tracks if a RealTrack is assigned to it. The RealTrack Medley Maker adds the capability for 10 additional RealTracks to be assigned to any RealTrack channel of the Mixer to be played either consecutively from 8 presets or all eleven instruments to play simultaneously, panned and volume automated.

PG Music developers also use MultiStyles that use RT 1152 as a place holder for track variations of instruments and also transitions.
