Like myself, Steve Brown believes in honest reviews over glowing reviews. Also like myself, Steve Brown is unlikely to work for professional music gear magazine publishers. This is because Steve Brown also believes in the Cave Johnson school of thought: When Life gives you lemons, burn Life's house down... with the lemons.
When Numark sent him an iDJ Live to review for DJ Worx (formerly Skratchworx), he wrote an honest one. DJ Worx refused to publish it. One of his chief complaints was that the jog wheels on the iDJ were far too laggy, so he set out to modify his review unit, to be able to playing on the iPad screen instead of the useless jog wheels.
Correction: Mark Settle from DJ Worx was quick to point out that they did in fact run his review. In the comments here he insists that the review appeared in full and unedited. You can see it at the SkratchWorx archive.
I am unclear on why the YouTube description says otherwise:
The folks at Numark were nice enough to give me an IDJ Live so that I could write a glowing review of it for Skratchworx. I wrote an honest review and nobody wanted it published. I also modified the controller and sent it back to them. (one might think that they implemented to locking mechanism from my idea)
Here is his demo of the modified iDJ Live.
