Will my MYTWorks Slider work with the spectrum?

You bet.  We support the following: 

• MYT Camera Slider Medium in 4,5,6 foot lengths https://www.mytworks.com/camera-sliders/
• MYT Camera Slider Large in 4,5,6 foot lengths https://www.mytworks.com/camera-sliders/

To make it go, you need a standard spectrum ST4 + the correct integration kit from eMotimo or MYTWorks.
