If you already own an S4 Mk1 gathering dust, do not sell it for pennies . Install Virtual DJ (free for home use with controller support in the trial, or $20/month for Pro). It turns a forgotten relic into a fully functional stem-separating 4-deck machine.
Enter (specifically the 2021-2025 builds, including VDJ 2025). Known for its adaptability, stem separation, and massive hardware support, VDJ breathes new life into old gear. But is it a match made in heaven, or a frustrating experiment in legacy drivers?
Introduction The Native Instruments Traktor Kontrol S4 Mk1 is something of a dinosaur in 2025. Released in 2010, it was the flagship controller for Traktor Pro, built for a time when sync buttons were still controversial and "four decks" meant you were a serious power user. Fast forward over a decade, and many units are gathering dust in closets, sold for under $150 on the used market.
VDJ’s default mapping is surprisingly comprehensive. It assigns decks A/B to channels 1/2, and C/D to channels 3/4. All EQs, filters, volume faders, crossfader, pitch faders, and the jog wheels work out of the box.
If you are buying new? Skip it. Get a used Traktor S2 Mk3 or Pioneer DDJ-FLX4. But if you find a Mk1 for under $120 and you’re on Windows, this setup is one of the best value-for-money controller rigs for bedroom DJs who want 4 channels and stem control without spending $600.
After spending 20+ hours with this exact setup (S4 Mk1 + VDJ Pro Infinity), here is the definitive long-term review. The Good: Virtual DJ recognizes the S4 Mk1 instantly. There is no need for complex MIDI mapping. As soon as you plug in the S4 via USB (using a printer-style USB-B cable ), VDJ’s hardware controller database detects it. You simply go to Settings → Controllers → Select "Traktor Kontrol S4 Mk1" → Hit "Use."
Replace the stock USB cable (it’s notoriously weak) and clean the pitch faders with compressed air. Then remap the "Shift" button to activate VDJ’s "Beatgrid Editor" – you’ll thank me later.
