Even the full Serato DJ Pro software pack is usually limited without an add-on controller plugged in, but with the Play expansion pack you get the full DJ experience, as long as you’re fine using a mouse or keyboard to perform. The layout includes multiple decks, filter controls and waveform views. That means you can prep sets and make mixes when you move away from your DJ setup to take some time on the couch, or soon enough even somewhere outside of your home entirely.

Serato’s free Play expansion pack offer is only available during the month of May for DJ Pro or DJ Lite users. After that, it returns to its normal price of $29. You can also visit the company’s “keeping busy” landing page for how-to guides, giveaways and other special offers.
