Arches ... Odd Or Even Number Of Segments?


Recommended Posts

I suggest an odd number. It gives you a segment at the top/middle, a nice visual transition from left to right and reverse.

But as Tim indicates there is no wrong answer (and I also use 5) I would suggest 5 being the minimum, 4 (or less) just doesn't look right.

Repeat... No wrong answer, unless... you're using a number other than 5. :P I think by now you see your answer (5), is what-ever floats your boat (5). ;)

I use 10 foot arches and the lights I used perfectly fit each 2 foot section resulting in a total of 5 sections per arch. You may want to build one before programming them. It's easer to make your sequence match your arch section count rather than the other way around.

No wrong answer. .... I use 5

I second this answer!

I use 5.... And there is no wrong answer.

People will say to use 4 or 8 because that number divides evenly with timing. But when using the LOR sequencer (if that is what you'll use) the "auto chase" function makes chasing over unequal channels easy and thoughtless.

Also it depends if you are using the sleeve method to arches (like I do) or you make one long continuous arch. Do you have room to store four or five 16' arch at the end of the season? The sleeve method helps with storage concerns but the continuous arch shows a fluid motion at the boundaries of each string on the arch.

For me, it's easier to sequence with an odd number of channels, preferring to create a split at the middle of the arch. I think this is something you need to test out for yourself.

Why don't people use an odd number for their mega trees?

I use 7 because that's all the channel space I had. In the coming 2013 year, I'll upgrade to a spiral tree with 8 channels of red/green/clear/blue minis/LEDs

I like the odd count because you can go from a single center point and spread evenly through the channel...

If you have an even number like 8... you turn on 2 in the center and spread evenly. I had a 10 count mini tree line and just didn't like it at all with 10, so I cut it back to 9.

Wouldn't that issue be the same with a mega tree? You need to start a middle effect/chase some where.

IMHO the odd arch number cannot work as well as even.

A chase does not care if odd or even, but I challenge anyone to show that an odd number translates better to most music than an even number such as 4 or 8.

Well, you can slice the pie any way you wish :) I'd keep the word "challenge" down to a minimum here lol ;) you are an Planet Christmas and people will see this post and actually take on this challenge haha (bigger bigger BIGGER)

As for a SPIRAL tree, the odd way in which the lights are wrapped will not identify exactly how many channels are on the tree OR the exact middle of the tree. It will be harder to tell exactly what channels are doing what. So in that instance, starting a center-out split on the spiral may not have an effect as something so blatent as a 9-tree tree-line or 8-channel arch etc... Currently I use 42 channels (4 colors x 7 channels) because it was all I had left in my arsenal of controllers from 2010/11 :) for 2012 I added 2 new controllers specifically for the Mega Tree so now I have 4 colors x 8 channels I can use which weren't there before. Was going to add the 8th but figured It was too much work to add another "leg" to the Mega tree this year since the display was already running.

Now I must say that I'm contemplating the expansion of my arches to 9 channels and making them longer and taller for 2013. I also notice that there are 16 channels to an LOR unit. I'm toying with the idea of trying 8 simply because I've not used 8 channels on an arch. So, I think I'm up for a little empirical research this year.

This is an absurd statement. I use 3 arches with 5 segments each and they look great. Not every display item needs to change for every beat of every song. Besides I prefer and recommend an odd number of segments. You get that middle that isn't available on even numbers - without using both the middle channels at the same time.

For me sequencing a song is only partially about the beat. It's also about the flow, and the entertainment factors. If I want the perfect beat - only, I'd go back to a Mr Christmas. We often way over analyze our on creations. We all slave over our sequences seeking perfection. The reality is if our sequences were only half as good as we make them - we would still be the only one to notice.

Please read and understand the post before commenting the statement is "absurd".

I did not say odd looks bad, what I did say is that even, in general, translates better to most music.

My challenge stands, I don't think you have shown or proven otherwise.

My first year of arches had 9 so I could light up the middle channel, sort of like an LED volume meeter. What I found was most songs lend themselves better to 8... 4/4 time... 2/4 time.... I also found that with 9 channels, channel 5 would cross the middle... with 8 channels, it was easier to split the arches in half.

There is no right or wrong answer... Odd or even.... I have had an easier time with most effects using 8 rather than 9.

What you are really saying here is you want bona fied proof that it looks BETTER. Well, you're not going to get the PROOF so challenge away. in any event, Craig has the right answer

There is no right or wrong answer... Odd or even.... I have had an easier time with most effects using 8 rather than 9.

And I have an easier time with 9 rather than 8. But getting back on topic.

I'm new at adding arches. What are your thoughts as to number of segments and odd or even number of segments? What are your reasons?

Thanks

He asked for reasons not an argument as to why we disagree.

I use mainly even numbers for display items. My 2 Stars are odd numbers unless you add in the "Firestick" then you have 12 channels. I have 5 channels for the points & 2 channels for the explotion (which was not in my original idea) just the 5 point Star. Even this I can go 8 channels now that I know what the Stars look like in action.

The bottom line is......... you need to make the decision on your own & then you live with it until the season is over & then go from there.
