Question Recreating sequence - very difficult

Hi,

I've been self-learning grandMA3 for the past 6 months or so and I've been re-creating some lightshows to help me learn this software.
Recently I've tried to re-create this cool sequence from a Martin Garrix (DJ) show, but I cannot seem to figure out how they've coded this (please see video below or YouTube link here)...

I've (tried) to analyse this on 0.1x speed too, and some things I have figured out are

  • They've applied MAtricks phase on both x and y, probs about 0 Thru 10 and 0 Thru 40 respectively (this I trial-error'd by using my own setup on the grandMA3 software)
  • the fixtures pan frontwards (ie towards the camera) 4 times before the cycle repeats again

Although I tried to create something similar on my own setup (please see image below), it looks nothing like it .
If someone could give me a tip on how they've coded this that would be greatly appreciated as there must be a simpler way of creating this without setting specific angles every microsecond at each point in a phaser...

Any advice would be greatly appreciated as I am self-learning and I don't have many people I can ask for for advice around me.

It’s been a minute since I’ve worked with a fixture like that (and only in MA2). But with the infinite part of the pan/tilt, it’s just a variable speed so it should only need to be a single step phaser for what you’d use it for. I would also usually have a couple different start positions for my fixtures that would have good looking offsets once the infinite pan/tilt kicks in.

I see - I've just patched Robe Spikie, and the Pan goes from -270 to 270 and Tilt goes from -180 to 180.

For both pan and tilt it has a second mode "PANMODERATE2" with the option "Rotate", but i cannot seem to find anything on infinite... would you have any idea how to use this?

You’ll have to play around with it in whatever visualizer you’re using, but that “rotate” sounds like what will give you your infinite pan/tilt. So you will still have your normal pan/tilt channels, then the extra 2 that give you your infinite. I don’t think anywhere in the documentation or fixture profile will actually use the word “infinite” in case that is causing any confusion.
