Since Tom was a long time user of Mark of the Unicorn's Performer 6 software, we decided to upgrade to a 27" iMac running Digital Performer 7, and install an 828MK3 audio interface as well as a Micro Lite MIDI interface. The number of Performer revisions between P6 and DP7? Thirteen!
Here is the preliminary placement of the 27" iMac. Eventually the stock stand was replaced with a VESA mount.
