In a month or so, I am having a rather large party on my property and am looking at renting some SCX500's. These will be run as "set and forget" and I will not have much programing time so I am looking at the built in macros and also the "audio active" feature. I know that the DJ end of the market often has pretty dodgy audio modes, but coming from a company like Martin, I was assuming it would be better. Does anyone have any experience with these fixtures, and specifically the macros and Audio mode? Is the audio effect actually any good? Thanks.
