2.PLEASE PLEASE release the midi learn function,or at least let us map external controllers in the "keyboard" section!!! !!!

3.When in browse mode in performance mode and I want to change the song works but only when i quit the browsing mode.The same thing with switching the channels - works only when I hit spacebar again.

4.Beat grid controls dont work on ddj-sz.

5.Can you make 4 banks of pad fx per channel?

6.Can loop (and loop roll) be quantized without the whole deck being quintized?

7.Thig program is a masterpiece and takes mixing to another level,and this funkction above will make it an absolute monster.Bow down to the creators.
