At its core, Cross DJ Pro 3.5.9 utilized Mixvibes’ proprietary Elastique v3 time-stretching algorithm from zplane.development. This was a critical upgrade from earlier versions, as it offered superior sound quality when pitch-shifting or tempo-adjusting tracks. At extreme tempo changes (e.g., slowing a 128 BPM house track to 100 BPM), artifacts were minimal compared to the grainy "rubber-band" sound of competitors like djay 2 or early edjing versions. The keylock function remained stable even with +50% tempo changes, a testament to the algorithm’s efficiency.
Latency was exceptionally low—typically between 5 and 10 milliseconds on an iPhone 6s or newer, rising to about 15ms on older Android devices (Android version parity was a noted weakness). The audio waveform rendering was buttery smooth at 60 frames per second on iOS, with the RGB waveforms providing clear transient information for drum-heavy genres like techno, drum and bass, and hip-hop.
When compared to its 2017–2018 rivals: cross dj pro version 3.5.9
Cross DJ Pro 3.5.9 excelled in hardware connectivity. It natively supported MIDI controllers over USB (via Apple’s Camera Connection Kit) and Bluetooth. Preset mappings existed for the Reloop Mixtour, Numark iDJ Live, and Pioneer DDJ-WeGO4, but the MIDI Learn function allowed users to map any knob, fader, or pad. This was revolutionary for mobile DJs in 2016–2018, transforming an iPad into a functional equivalent of a $1,000 standalone controller.
Wireless integration was also notable. Ableton Link support allowed multiple Cross DJ instances (or other Link-enabled apps like Loopy or Gadget) to synchronize BPM and phase over Wi-Fi. For live performers, this meant a DJ could sync loops with a producer running Ableton Live on a laptop without any physical cable. Cross DJ Pro — Version 3
Version numbers in the 3.5.x line typically indicate incremental improvements and bug fixes rather than major new features. For a 3.5.9-style update you can expect:
Yes, but only for specific use cases.
It is a goldilocks release—not too old (missing critical features), not too new (bloated). If you own an iPad Air 2 or an older Android tablet that cannot run modern DJ apps, Cross DJ Pro version 3.5.9 turns that museum piece into a fully functional 4-deck mixing rig.
However, if you are on a modern iPad Pro or a flagship Samsung tablet, do not hunt for this version. You will be disappointed by the lack of high-res display scaling, missing Apple Silicon optimization, and no access to streaming services. Backup playlist on USB and export a secondary
For the retro-DJ, the minimalist, or the backup-seeker, version 3.5.9 is a time capsule of mobile DJing's golden age—when apps were paid once, worked offline, and fit entirely within 200MB of storage.
