.M3U Splitter?

[PROducer]

I'm toying with the idea of using MusicGen to schedule my music, but it seems to only output a single .m3u playlist per day.  RadioDJ really doesn't like loading playlists that large, even if the files are already in the database, so I'm wondering if anybody on here knows of any software that will split a .m3u playlist into multiple files?

Thanks
PROducer.

Yep.

Check if it is what you looking for.

M3Util.zip

On a small test working fine.

Hello, is there a pdf help file? My Windows 7 Pro does not allow me to open the downloaded file. 
Thank you all.

[Jhonny]

I don't have a pdf help file, sorry.

 Thanks Jhonny,   could someone please explain how this software works?

I've got a php script that does this. I'm not at my computer right now (on my phone) but I'll attach it when I'm back there. You'll need server software to use FYI. I use XAMPP.

Here is the script. Customize it however you want. Just keep in mind that you will need an END OF HOUR marker.

Been almost a week since I asked this question, but I've been busy trying a number of different methods.  Thanks Jhonny for your solution... it works, but I couldn't figure out how to split files hourly instead of the default 80 minutes.  It was just too weird of a split for my needs.

Marc, thanks also for sharing your php script.  I'm using MusicGen Lite to schedule, which has it's own foibles, especially when outputting an .m3u file.  Only certain things wind up in the .m3u export which extremely complicates how to build the categories, etc.  I'm sure someone may find a use on their own system.

My solution: I wound up searching for a "text file splitter" which there are a lot out there. (I'm thinking it must be a project in some computing courses... there's really that many simple text file splitters) but most split at xx lines.  What I needed was something to split at an hour marker. I found a program called TextWedge Text File Splitter.  My only issue with it is it doesn't "remember" how you want to split your files, so you need to set it up each time.  It's a simple process, but would be nice if you didn't need to.

I just got everything setup and working this morning in RadioDJ and it's sounding great!  The main reason I'm doing this is because my weekends are double-play, and I was noticing I wasn't getting great artist separation using an SQL Query to create playlists.  The setup for artist separation works great if you're using rotations, but if you switch to SQL queries for the weekend like I do, suddenly you'll get stuff close together that you don't want.

TextWedge exports sequentially numbered files, starting with 01, so that required me to create a new event for every hour of the day (by day) and it loads the playlist for every "hour +1" because there is no 00 file.  I load the next hour to the bottom of the queue at the :45 minute mark, so if an hour is a little short, it doesn't run out of music before the next hour load.  The only time I don't is at midnight, when I load the hour at 2 seconds past midnight.  I also clear the queue before I do this to get everything back into sync.

So far, I'm very happy with what I'm hearing.  My double-plays are now separated better, and I'm getting pairs of Bands and their solo artists together instead of two Band feat. Artist!

       

Now, to figure out how to make it simpler to voice track with the scheduling software!
