Song properties dialog:


Here is the most complex dialog of djmixpro. Do not be scared by the many fields in the dialog, as it will become clearer very soon.


Mixing options tab

Mixing options tab


Note : the next two fields do not appear when properties of several songs are displayed at the same time.

Title: the song's title if the file provides a mp3 title tag.

>Length : the song's length.

Note : the following fields appear even when properties of several songs are displayed. In such a case, if all songs have the same property value, the value is displayed. If songs have different property values, no value is displayed. Modifications apply only on properties that are set (not in indeterminate state).

Try Beatlock mix at end : this song is going to be analysed by the Beatlock routines. At the ending position, djmixpro will try to perform a Beatlock mix between this song and the next in the list.

Use normalization : at Beatlock analysis time, the song perceptive volume will be computed. The song volume will be adjusted at play time so that every song has perceptualy about the same volume.

Use fading auto detection results : this song is going to be analysed by a fading search routine. If fading in/out already occurs within the song, no fading in/out is performed by DJ Mix Pro. If not checked or if not starting at pos 0/stopping at end of song , the 'Use fade in/out' are used to determine if djmixpro has to perform fade in/out rather than the 'Use Fading auto detection results' .

Fade at begin : make song volume rise smoothly from 0 to about 50% when song starts. Note that when use fading detection is checked and song starts at position 0, this property is no used. A fade in is done if no fade in was detected in the song.

Fade at end : make song volume smoothly fall to 0% when song stops. Note that when 'Use fading detection' is checked and song stops at end, this property is no used. A fade out is done if no fade out was detected in the song.

Pitching done on both songs : if checked, both songs will change their pitch when mixing. If not checked, only the new one will. Changing pitch of both songs, you will be able to mix more songs togeither since the 2 songs allow about 16% pitch change instead of 8% with a single song.

Using volume (percent) : Target volume after fade in (default 50%) . Is automaticaly set if you use normalization. Is overridden if you touch the playing song's volume control.

Fading in length : length of fade in ( time to rise from 0 to used volume)

Fading out length : length of fade out ( time to go down from used volume to 0)

Pitching length : length of pitch change for Beatlock mixes ( time to go from 100 to target pitch or from target pitch to 100%)

Start at : position within song where mix starts. This doesn't apply for songs not started by a mix.

Stop at : position within song where mix stops. Can be a negative value if relative to the end of the song.

Mixing length : length between beginning of next song's fade in and end of current song's fade out



Tag infos tab

Tag infos tab

Beatlock infos tab

Beatlock infos tab


Note : the following fields do not appear when properties of several songs are displayed at the same time.

Title : the song's title if the file provided a mp3 title tag.

Length : the song's length.

BPM : this song's BPM. Available only if Beatlock status is STATUS OK

Volume when normalized: song computed volume level for automatic volume match.

Number of beats : the number of beats collected during the Beatlock analysis. Available only if Beatlock status is STATUS OK

Coverage of file : percentage of file containing beats detected by the Beatlock analysis.

Beatlock status : the song's Beatlock status. Is may be any one of the following statuses :NO STATUS (YET), BEEING BEATLOCKED,NOT USING BEATLOCK,STATUS OK, STATUS FAILED, BLK NOTALLOWED.

NO STATUS (YET) : this song has not been analysed yet by the Beatlock routines.

BEEING BEATLOCKED : this song is currently analysed by the Beatlock routines.

NOT USING BEATLOCK : this song doesn't have the use Beatlock mix property.

STATUS OK : this song was successfully analysed by the Beatlock routines. In the registered version, Beatlock information is saved in a file to avoid recomputation when program restarts.

STATUS FAILED : the Beatlock routines failed to analyse this song.

BLK NOT ALLOWED : Beatlock analysis is currently down (you selected the Action->Stop Beatlocking menu).


Has silence in : (indicative) tells if song starts with a silence.

Has silence out : (indicative) tells if song ends with a silence.

Has fade in : (indicative) tells if song starts with a fade in.

Has fade out : (indicative) tells if song ends with a fade out.

Erase beatlock files : deletes the selected song(s) cache file(s), which contain beat position, BPM, and fading information. This is useful to recompute the cache file.

Divide BPM by 2 : You can use this to fix the BPM and beats if you feel automatic detection got a wrong BPM.

Shift by 1/2 beat You can use this to fix the beats if you think automatic detection used the opposite beats (snares instead of drums for example).

Double BPM : You can use this to fix the BPM and beats if you feel automatic detection got a wrong BPM.
