FULL WRITTEN REVIEW IN LINK ABOVE ^^^^^^^
The Pioneer DDJSR is a compact and professional Digital DJ Controller that fits nicely within the new Pioneer DDJ controller range as a trimmed down twodeck version of the DDJSX which is still capable of controlling all four virtual decks of Serato DJ. The new Pioneer DDJSR has a smaller footprint than the DDJSX and adds a new PAD PLUS button that gives the 16performance pads even more functions than before.
