IDS OVER 3 HOURS

FileName=C:\IDS\ID1~0.wav

1) Create a directory on the C: drive called IDS

2) Copy the script " ids over 3 hours.ini " into this directory

3) Prepare 12 sound files called ID1~0.wav to ID12~0.wav

Note: these files can be anything, promo, Ids, jingles, ads etc.
You need to keep track of content, and can replace them as required as long as you keep the same filename. They need to be wave files of course, if you wish to use mp3, edit the script (can be done as a batch job).

4) drop the 12 audio files into the directory you created on the C: drive.

5) Load the script called " ids over 3 hours.ini " into your scheduler

6) In "Options", under "scheduler". "click skip evnets that are overdue" and set it to say 10 minutes.  You can experiment with this and adjust as required to match your format.

That's it. The 12 files will cut in every 15 minutes or so, and wait until the track loaded in the master playlist has finished. In this way, you will have an irregular pattern.  Note that files are are including the ~0 in their name, so no overlap.

You can customise this script. Text pad is a start, there are much better editors available.

IDS OVER 2 HOURS 
Same procedure, except that rotation of IDs will take place every 2 hours with 10 sound files only.
