Korg have released the Pa5X, the new flagship model in the Professional Arranger product range which is available in 61, 76 (semi-weighted) and 88-key (weighted piano-style action) versions. This successor to the Pa4X has been completely redesigned and features Korg’s new EDS-XP sound engine along with a powerful new operating system.


Each model’s front panel is built around a large central touchscreen that displays a newly designed GUI, and plenty of hands-on control is provided via assignable Pad Matrix and Mixer sections. Mixer volume, drawbar settings, microphone mutes, lyrics scroll commands and more can all be controlled directly from the front panel. Assigned control functions are shown by an auxiliary strip display, allowing users to keep track of the hardware controls even when the main display is set to a different page. Programmable LED buttons on the control panel have all been careful matched to the colours used in the GUI in order to ease navigation and ensure intuitive operation.

Combined with new features such as Round-Robin drum and percussion performance, Smooth Sound Transition and Sound-Controller 3 functionality, Korg say that the Pa5X provides an unprecedented level of sonic realism and expression. On-board sounds also benefit from the assignable controls, with faders, switches, joystick and ribbon controllers all able to be configured to modulate any adjustable parameter.

Sound Library

The built-in sounds range from realistic acoustic instruments to electric vintage keyboards and synths, as well as fantasy sounds and special effects designed for game, media, video and cinema production. Sounds from Korg’s SV-2 Stage Vintage Piano are included, as well as a selection of sounds from the Kronos and Nautilus synth workstations. A new Drawbar Organ that utilises the physical controls is included, and new effects derived from the CX-3 Combo Organ also make an appearance. The device’s new Drum Kits feature increased realism thanks to the use of technology based on round robins, and users are able to record their own samples or import sounds in standard file formats such as AIFF, WAV and SF2 for use with the built-in sampler.

Vocals captured by the microphone input can be used to generate four-voice harmonies, and an Auto-Pitch feature provides access to modern pitch-corrected vocal sounds. Guitars have not been left out, with the Pa5X including vintage pedal and amplifier simulators, with the ability to save chains of up to four effects as presets.
