If you are a mobile DJ, open-format DJ, or remixer, Virtual DJ is arguably superior to rekordbox on the FLX4. The stem separation alone changes how you can perform.

When Pioneer DJ released the DDJ-FLX4, it was hailed as the ultimate controller for beginners and mobile DJs. It bridged the gap between casual smartphone mixing and club-standard performance. But while it ships with a license for rekordbox and is compatible with Serato DJ Lite , many DJs wonder: How does it perform with Virtual DJ?

If you are strictly preparing USBs for CDJs in a club, stick with rekordbox. But for weddings, parties, streaming, and creative mixing—install Virtual DJ. Your FLX4 will feel like a $1,000 controller.
