Waves Multi-Rack is a software that can interface with a StudioLive mixer. While there isn't necessarily a video created by PreSonus Audio concerning how to use the software with our mixer, there is some information Waves has on their website:
An overview is found here of the Waves Multirack software: http://www.waves.com/mixers-racks/multirack
StudioLive specific setup instructions are found here: http://www.waves.com/live-sound/presonus#overview
NOTE: We do have an overview of using the Auxiliary Inputs generally on a StudioLive mixer, but it's expressed here through Studio One software. This can be correlated to Waves Multirack in theory.
For more questions with their software, be sure to contact Waves support. For questions with our software and fuctionality, please search through our Knowledge Base for FAQ's, which includes an article on making sure your mixer is functioning correctly, or Contact Technical Support should you have any other concerns.
