I put together a New Year's Eve Party Light Show this year and sequenced a shortened version of Mariah Carey's Auld Lang Syne -
https://vimeo.com/150398059The sequence depends on a megatree and a matrix. I also use a star, arches, single strands and some starbursts but you can map these to anything you want and it will look fine. All elements in my show, except the DMX and matrix are also grouped together and this is where most effects are applied.
If you want to add it to your show, it's a simple sequence, follow the steps below and you'll have it up and running in 30 minutes or less:
1) Download the song:
https://www.amazon.com/gp/product/B0048Y7V6K?ie=UTF8&keywords=mariah%20carey%20auld%20lang%20syne&qid=1451539065&ref_=sr_1_1&sr=8-1 and place it in your show folder
2) Copy the Audacity data files folder from
https://www.dropbox.com/sh/vp0il22sffl4hzh/AACyNR_n1ajgiC4yX8myM1Oka?dl=0 to your show folder and open up the Auld Lang Syne.aup file.
3) Export the MP3 to your show directory call it Auld Lang Syne-short.
4) As described above, in Xlights create a group called "All - 2015 no matrix" or something like that.
5) Import the sequence, map Mega-Star to your star, M24TREE120 to your megatree, and Matrix 96x64 to your matrix.
6) The Arches, Starburst and Lawn Stake Globes keep the beat, so map them to elements that you normally use for beats. The L & R sides are identical.
7) I've got some DMX elements - not shown in the video - you can ignore this but if you've got DMX elements, I've replicated the sequences from the Arches and Starburst on these, so they may work for you.

The only tricky bit is the fan sequence on the megatree. I adapted this from Gil's Shut Up and Dance sequence and given that I struggled with this effect at first, here are a few pointers.
a) You need a Morph effect on N/2 layers where N is the number of strands on your megatree.
b) The first layer controls the effects on the first and last strand. You need to set the Repeat Skip on the Options pane to N-1 (I've got 24 strands, so the number for me is 23.)
c) The second layer controls the effect on the second and N-2 strand. Depending on your N, you will need to adjust X1a on the Start pane and X2a on the End pane to a new value (X1a=X2a), and adjust the Repeat Skip Count to on the Options Panel to N-3
d) Repeat for each layer below until you reach the center two (or 1) strand. Note: you may need to add or delete layers.
If that's too much of a pain, try replacing this effect with a Garland effect

That's it. Enjoy.
