Hi Nick,
To make a chase with these fixtures, you have to select all the sub fixtures.
Then you can start a chase from the Chase tab.
With the "Phase-Shift" you can make waves etc.
In the left down corner of Visual DMX you can open the Subs tab, right click and select "All".
Then go to the Team tab, right click again and click "Add, include current selection"
Now you only have to select the Team that you would like to use, click a dimmer Chase, and click start.
When you right click the chase that you are running you can change the timing setting to Clock, with this set, you can use the Speed fader to set the chase speed.
Now play around with the Phase-shift to create a wave for example.
Once you get the hang of it, you can open the chase in the sequence editor and start modifying it to create your own.
Please give it a try and let me know

Regards,
Bart
