djay 5.6.6 Adds Pro Mixer Support

djay’s latest update is small, but booth-focused

Algoriddim has released djay Pro 5.6.6, a targeted compatibility update that matters most to DJs plugging into club-style AlphaTheta and Pioneer DJ mixer setups. According to the official macOS release notes, the update adds official support for the AlphaTheta DJM-V5, Pioneer DJ DJM-A9, and Pioneer DJ DJM-V10, while also adding a CDJ workflow improvement that marks queued tracks on CDJ screens.

The Windows release notes list the same headline mixer support and CDJ queue-screen change, and Algoriddim’s iOS release notes confirm official support for the DJM-V5 and DJM-A9 on iPhone and iPad. Algoriddim’s community announcement also notes that DJM-V10 support applies to macOS and Windows, while DJM-V5 and DJM-A9 support covers macOS, Windows, and iOS.

Why this matters for DJs

The key phrase here is official support. DJs have long been able to route audio creatively with class-compliant interfaces, external mixers, and manual audio settings, but official mixer support can remove a lot of uncertainty: channel routing, audio-device selection, and booth setup become less of a pre-gig science project.

This is especially relevant for djay users who want to move beyond controller-only setups. The DJM-A9 and DJM-V10 are common high-end booth mixers, while the newer DJM-V5 is AlphaTheta’s compact 3-channel performance mixer. Adding these devices to djay’s supported hardware story makes the app feel less like an alternative ecosystem and more like a practical option for mixed booth environments.

The CDJ queue marker is a workflow feature

The CDJ change is easy to underestimate. Marking queued tracks on CDJ screens gives laptop-and-CDJ users a clearer handoff between the software library and the hardware display. That matters in busy booths, back-to-back sets, and any situation where a DJ is moving quickly through requests, alternates, and prepared transitions.

It also fits a wider trend: DJ software is increasingly expected to treat connected players and mixers as part of one integrated surface, not just as audio/MIDI endpoints. djay has been moving steadily in that direction with OneLibrary, Pro DJ Link-style workflows, and deeper hardware feedback.

Gig checklist before updating

• Update before rehearsal, not at the venue. Mixer-support updates can change audio-device behavior.
• Test external mixer routing. Confirm each deck lands on the expected DJM channel.
• Check headphones and booth output. Don’t assume cue routing survived the update.
• If using CDJs, test the queue display. Make sure your connected players show the expected state.
• Keep the previous installer available. Small compatibility updates are still worth treating as gig-critical software.

The takeaway

djay 5.6.6 is not a flashy feature release, but it is an important booth-readiness update. For DJs who use djay with pro mixers, CDJs, or hybrid laptop-and-club setups, official support for DJM-V5, DJM-A9, and DJM-V10 moves the software further into serious venue territory.
