Topic: Xdj az problem deck 1&3 and 2&4
Subject: Urgent Issue: Pitch Fader Jump on Layer Switching (AlphaTheta XDJ-AZ)
​Hi Atomix / VirtualDJ Team,
​I am using the AlphaTheta XDJ-AZ with VirtualDJ Pro (Infinity License).
​I am experiencing a very frustrating issue with the pitch fader when switching between layers (Deck 1 to Deck 3, or Deck 2 to Deck 4).
​Whenever I switch layers, the hardware sends a raw absolute MIDI state dump, causing the software pitch/tempo to jump instantly to the physical fader position.
​I have extensively tried fixing this using VDJScript (pitch_takeover, soft_takeover, conditional scripts, etc.), but all surface scripts fail because the hardware value overrides the software engine before the script executes.
​This makes 4-deck live mixing very difficult. Please update the official native XML definition/driver for the AlphaTheta XDJ-AZ to enforce a driver-level Soft Takeover (Catch-up) on layer switches to block these hardware jumps.
​Looking forward to a fix in the next update.
​Best regards,
Moamen Kwamney

I guess you're using a quite old VirtualDJ build ?
This has been addressed for quite some time.
 

Subject: Re: Pitch Fader Jump Issue on AlphaTheta XDJ-AZ (Latest VDJ Build & Latest Hardware Firmware)

​Hi Support Team,

​Thank you for the quick reply.

​To clarify, I am fully up to date on both hardware and software:

​VirtualDJ Pro: I am running the latest official build with my perpetual Infinity License. ​AlphaTheta XDJ-AZ: My controller is updated to the latest official firmware (Version 2.00).

​Despite being on the latest versions for both the software and hardware, the pitch fader jump / drift issue still occurs on layer switches (e.g., Deck 1 to 3 or Deck 2 to 4), specifically when applying custom VDJScript commands / Shift mappings. The custom XML appears to bypass the native driver-level soft-takeover/catch-up logic.

​Could you please advise on how to maintain custom VDJScript actions while forcing the VirtualDJ engine to keep native driver soft-takeover active on layer changes?

​Please help me get this resolved.

​Best regards,

Moamen Kwamney
