A Range is the portion of a song that will be used in the Automated Beat Mixing process in OtsAV. During the Automated Beat Mixing process, the Outro (end) of the playing song will be beat mixed into the Intro (beginning) of the next song. The graphic below shows a simple example of the beat mixing process.
Using the Range Start

Match Point 
, and
Range End 
markers in the Edit Beat Info window, you can specify exactly
how to beat mix songs into each other.
Intro and Outro Ranges can be as long or as short as required. Range lengths should match the sections of the song.
For example, an Extended Club Mix version of a song may have ranges that cover 1 or 2 minutes, as generally these ranges will contain only a beat and some basic instrumentation. more...
A Radio Edit of a song may only contain a few beats, depending on the length of the intro and outro of the song. more...
During an Automated Beat Mix in OtsAV, the Match Point from the Outro Range of the first song, is aligned with the Match Point from the Intro Range of the second song.
Intro Range
Setting the markers for the Intro of a song is a quick process. Firstly, make sure you have calculated the BPM accurately. The next step is to position the Match Point marker.
The Match Point marker should be positioned on a 1 beat, just as the song is gaining momentum, or the energy level of the song increases. Typically, this is where the intro of the song ends, and the main body of the song commences.
Note: The graphic below, for Yeah by Usher, has the Match Point marker set on a 1 beat, where the vocals "Yeah, Yeah, Yeah..." begin, as this is where the energy level increases.
Tip: Holding the CTRL key on your keyboard while dragging markers will snap them to the beat grid.
The Range Start marker should be dragged to the earliest point where you want the audio to be part of the beatmix. If you don't want part of the intro played during automated beat mixing, position the marker immediately after the unwanted audio.
Note: The graphic below, for Yeah, has the Range Start marker set immediately after the words "Peace up, A Town", as we don't want to hear this in the beatmix.
The Range End marker should be dragged to a position where you want the audio to stop being included in the beatmix. This may be immediately after the Match Point (which would effectively produce a "slam" mix), or 8, 16, 32 or 64 counts past the Match Point.
Note: In the Yeah Intro (below), we have set the Range End marker 16 beats after the Match Point. At this point in the song, a verse commences. During an automated beatmix, the Outro from the previous song will have ended by this marker.
The graphic below shows the Intro Range that has been setup for the song Yeah by Usher.

Outro Range
Setting the markers for the Outro of a song is also a quick process. Again, make sure you have calculated the BPM accurately. The next step is to position the Match Point marker.
The Match Point marker should be positioned on a 1 beat, just as the song is losing momentum, or the energy level of the song decreases. Typically, this is either where the outro of the song begins, or the song ends, or the main body of the song concludes.
Note: The graphic below, for Yeah by Usher, has the Match Point marker set on a 1 beat, after the vocals have finished in the song. This ensures that all of the vocals are heard during the beatmix, before the incoming song takes over.
Tip: Holding the CTRL key on your keyboard while dragging markers will snap them to the beat grid.
The Range Start marker should be dragged to the earliest point where you want the audio to start being part of the beat mix. If you don't want part of the outro played during automated beat mixing, position the marker immediately after the unwanted audio.
Note: The graphic below, for Yeah, has the Range Start marker set immediately before the vocals "Take that, rewind it back..", as this is where we would allow a beatmix to start from.
The Range End marker should be dragged to a position where you want the audio to stop being included in the beat mix. This may be immediately after the Match Point (which would effectively produce a "slam" mix), or 8, 16, 32 or 64 counts past the Match Point.
Note: In the Yeah Outro (below), we have set the Range End marker 16 beats after the Match Point. At this point in the song, a verse commences. During an automated beatmix, the Outro from the previous song will have ended by this marker.
