The latest firmware addresses style transitions, MIDI traffic optimisation and tempo control issues based on user feedback.
Korg has released OS version 1.4.2 for the Pa5X arranger workstation, delivering fixes and improvements across the system based on extensive user feedback since the flagship model’s launch.
Catch up on all the latest news here.
The update tackles several significant performance issues that Pa5X users have reported. Among them is the style-transition volume impact, which has been a point of frustration for live performers relying on smooth transitions between arrangements. Additional improvements to style-element triggers—particularly for fill-ins programmed as quarter notes—should make performance feel more responsive and predictable.
MIDI users will appreciate the implementation of an additional SysEx filter designed to reduce MIDI traffic, addressing potential bottlenecks when running complex setups. Expression values for tracks in “OFF” mode have also been corrected, ensuring more accurate playback behaviour across the board.
Several workflow refinements round out the update. Tempo buttons that were previously blocked while metronome and search windows remained open are now accessible, removing the interruption to live performance flow. Time-signature optimisations when using different signatures in the arranger should make complex arrangements more manageable, and MP3 file time-calculation has been improved for more accurate playback information.
Korg has confirmed that development on the Pa5X operating system will continue throughout 2025 and beyond, with “many exciting developments” planned. For a workstation that represents the top of Korg’s arranger line, ongoing support and refinement demonstrate the company’s commitment to long-term product development rather than simply moving onto the next model.
Pa5X users can download OS version 1.4.2 now from Korg. For local enquiries, head here.
