Here is a detailed summary of the KORG Pa5X OS Version 1.4.3.1 update, including all major features introduced in the v1.4 series and cumulative improvements from previous versions:
OS v1.4.3.1 Specific Improvements and Bug Fixes
The latest incremental update focuses on system stability and critical performance fixes:
• Fill Note Logic: A regression was fixed where sustained notes were being interrupted when pressing the FILL button at specific positions within a pattern.
• MP3 Time Accuracy: Corrected an issue where MP3 Song time calculation was inaccurate specifically when TEMPO LOCK was enabled.
• System Stability: Addressed issues regarding Scale resets via MIDI, display refresh errors during Cut & Paste operations in the File menu, and handling of special characters in musical resource name.
• Pad Lock Behavior: When Pad Lock is enabled, Pads now continue to play when selecting a different Style, automatically adjusting their Tempo to match the new selection.
Major Features Introduced in v1.4.0
• New File Format: A new format for User data was introduced to significantly enhance system speed and reliability.
• Style Creator Bot: This powerful tool can automatically create a full Style from a standard MIDI file, including all Style Elements, Pads, Keyboard Sets, and Chord Sequences.
• Recording Studio: A brand-new mode that creates a MIDI Song from a live performance. It features a visual timeline where users can edit “regions” of Styles, Chords, Pads, and Keyboard Set.
• Redesigned Song Record/Edit: The entire MIDI Song recording and editing environment has been revamped to be faster and more intuitive.
• Free Rearrangement: User elements (Styles, Pads, Keyboard Sets, etc.) can now be rearranged freely within their banks, rather than being restricted to alphabetical order.
Musical Resources and Sound Editing
• New Content: This update cycle added 46 new Styles (Pop, Dance, Rock, Ballad, etc.) and dozens of new Sounds and Pads.
• Advanced Drum Editing: Drum Layers have been increased to sixteen, improving compatibility with complex third-party libraries.
• Expanded Memory: The maximum number of Samples in memory was increased to 53,000, and the preload buffer was expanded to 420MB.
• Microphone Processing: A De-Esser was added to the microphone effect chain to remove sibilance from voice.
Workflow and Cumulative Features (v1.1 – v1.3)
• KAOSS Technology: Integrated KAOSS effects allow for live transformation of music flow, morphing between variations, and reshaping rhythms via the touch interface.
• Pa4X Data Conversion: Extensive support for converting SET folders from Pa4X into the Pa5X KST format, preserving User Sounds, Styles, and SongBook entries.
• Add-On Support: The system now supports external Add-On packages, allowing users to load new collections into a dedicated “Local” area without overwriting User data.
• Matrix Pad Enhancements: Chord Sequences can be triggered, and SongBook songs can be selected directly from the Matrix Pads.
• Hardware Support: Added support for microSD cards up to 1TB in capacity.
Important Update Note: Installing this OS update will overwrite all Factory and User data. It is mandatory to perform a “File > Save All” operation before updating to preserve your data, followed by a “File > Load All” once the update is complete.
