A Beatport article from May 2008 shows a snapshot of Deadmau5's technical rider. This is taken from his performance at the Beatport stage at Movement 2008. The third item on the top row, right below the MacBook Pro, is the Apogee Ensemble audio interface. The original article can be found [here](http://news.beatport.com/blog/2008/05/24/deadmau5-technical-rider/).more
Steven uses this audio interface in his home studio. You can watch it in a lot of pictures and videos. You can see the item at the minute 1:38.

"My desktop Mac is an eight?core Intel with 8GB of memory, and I have Apogee Ensemble for going in and out of the computer, and Brent Averill BAE 1272 and BAE 312A preamps, plus a Universal Audio 1176 compressor. Almost everything I track goes through the 312A, then the 1176 and into the computer. Everything else is done in the box. My master keyboard is a Roland A37, my monitors are the Adam 7s, and I recently acquired an Adam Sub 8 bass speaker. My room has some acoustic treatment, with stuff above my head and in front of me. I also have a large selection of analogue keyboards, organs, Moogs, ARPs. I love these things and I have about everything from the '60s and '70s. I've sampled many of them in Logic's EXS24 sampler, so I have a bunch of unusual and imperfect?sounding sounds that I can use for writing and arranging.”more
I don't know if I got a bad one or what, but this thing likes to make you aware of its existence. Most of the time it behaves, but sometimes it will go MAX VOLUME for no reason. It also was throwing loud bursts of white noise into the audio stream. I tried to get Apogee to fix it or exchange it, but no luck. It's a piece of hardware, and it's always acted up. I keep it on all the time, like most gear, but it needs to be shut off and rebooted every once in a while.
High-end digital converter manufacturers Apogee are Apple's audio partner of choice, and their latest Firewire interface is aimed squarely at Mac users with a taste for quality.
