This mapping is for the Numark iDJ Pro controller to use with Algoriddim Djay Pro on your MAC.  All knobs are mapped including the scratch button. 

Requirements:  In order for this to properly work you will need the following:

1) iDJ Pro USB cable - Connects your Numark controller to your MAC.  I just did a search for "iDJ Pro USB cable" on Ebay while writing this and found some listed on there.

2) An iphone or iPad with the Djay app - There is a Free djay LE version in the app store.  This is required to complete the handshake between the iOS device and the controller in order to use the Numarks soundcard.
