KORG Pa5X OS 1.5.0 is available now, adding 40 Styles, synchronized Pads and more control when importing MIDI into a Style. Search, Song Edit and MP3 playback also receive useful changes. Installation replaces Factory and User data, however, so owners need to make a complete backup first.

KORG Pa5X OS 1.5.0 makes Style building more flexible
OS 1.5.0 can import a generic MIDI file into one selected Element and Chord Variation without replacing the rest of the Style or Pad. The file must be a format 0 Standard MIDI File, and each imported variation can contain up to 32 measures. Tempo changes are supported, but meter changes are not, and some Style parameters still need to be programmed manually. The standard Pa5X also receives 40 new Styles covering pop, ballads, dance, rock, Latin dance, jazz, funk and blues. KORG has also published a video about Pa5X System Update 1.5.
KORG demonstrates the main Style, Pad, search and playback changes introduced with Pa5X OS 1.5.0.
Pads now follow Styles and Songs more smoothly
Pads can now start automatically in sync with a Style or Song. One Shot Pads play once, while Loop Pads continue until you stop the Pad or playback. A locked Pad also keeps playing when you select another Style or SongBook Entry, adopting the new tempo instead of stopping. Smart Fill offers another useful live change, letting accompaniment tracks continue their current pattern when a late Fill sends the drums, percussion and bass to the Fill pattern. More detail is available in this Smart Fill workshop video.
KORG explains Style Elements and shows how the new Smart Fill behavior responds to late Fill triggers.

Search and Song Edit now allow safer choices
Search results are now preselected rather than loaded as soon as you touch them. You can inspect a result, view its full path and then send it to the required Player, reducing the chance of loading the wrong file during a set. Song Edit gains an Undo command that identifies the latest eligible action and shows up to five earlier actions in its history, although KORG says not every edit supports Undo. Long paths are easier to read because the display keeps both ends visible, with the hidden middle available through a tooltip.
Back up the Pa5X before installing the update
The update overwrites both Factory and User data, so use File > Save All before starting. Download and extract the 419.4 MB ZIP, then copy the PKG file to a USB drive with at least 500 MB free. The updater works from any earlier Pa5X operating system, and owners do not need to install the intermediate releases first. KORG says installation can take up to 15 minutes, during which the instrument must remain powered on. After the first restart and preload process, restore the backup through File loading operations.
