The Lighting Controller

Hi Everyone!
Love the software and the Livemobile app.
I have a very sluggish system at the moment.
Using all DMX cables.
The lighting scenes are not reliable on cue.
I'm not sure if it's my MacBook that is causing the delays or do I need to rewire the system so other lights are first in the chain?
I am using a dmx terminator on the last can.
Any troubleshooting or advice appreciated!
Thanks everyone!

Hi! thanks for the reply! I am using .Wav files but the system is still very sluggish. even without the .wav audio file in the timeline the lights just don't want to respond that well. hmmm? thanks for any help:)
