Designing Audio Hardware For Live Show Backing and Visuals

[adf]

Hi, I'm working on designing some audio hardware and trying to collect info from musicians to find out what would be useful for them. If you get a chance can you please fill one of these surveys (it's quite short) and also pass the link on to any other musicians who might use backing tracks / visuals / synced lights or midi controlled devices etc in their live show? Thanks!
