man welcome to the world of the cdj400, it was ment to be fully midi and digital but pioneer decided to cut it away from the rekordbox software (even tho it was admited by pioneer that the software would work with an update on the 400) purley for the resson it would take sales away from the 900 and 2000 the reason the 900 is in the shadow of the 2000 is simple as it has happened in the past aka cdj 1000 cdj800 its all about maintaing cutomer satisfaction in the sence of that if you pay the best you get the best
