Here's what Korg say about the PA5X Series

Pa5X is the new flagship in the KORG Professional Arranger lineup, redefining an arranger keyboard. Completely redesigned with a state-of-the-art sound engine and a streamlined color-driven user interface, Pa5X produces a stunningly rich and unique sonic experience that inspires you to create and perform!

Pa5X comes packed with thousands of inspiring Sounds and hundreds of fresh Styles, all instantly accessible through an inviting workflow. A completely new front panel featuring an assignable Pad Matrix and Mixer section, multicolored LED buttons, and a huge tilt-able touchscreen puts you in control of your music making experience at all times. Pa5X excels both as a live performance instrument and as a powerful creative tool in the studio, allowing you to find your ideal sound no matter where your music takes you.

Premium Quality and Elegant Design

The Pa5X was designed with elegance and durability in mind, featuring a sturdy aluminum body and genuine wooden side-panels for a luxury appearance. All of the keybeds on Pa5X provide an authentic feel and full control of expression for any playing situation. The 88-key weighted action has a realistic piano-like touch while the 76- and 61-key versions feature lighter touch semi-weighted keys. All the keybeds include aftertouch control for added expressivity.

Modern and Streamlined User Interface

At the center of Pa5X is a large 8” tiltable touch screen that displays a completely redesigned GUI (graphical user interface). This makes all the sounds and features of Pa5X easily accessible to home and studio musicians as well as live performers. The colors in the display are carefully matched to the ones used in the LED programmable buttons on the control panel. This color driven interface allows you to easily navigate Pa5X, adding color to your music!

Powerful EDS-XP Sound Engine for Rich and Inspiring Sounds

KORG Professional Arrangers have set the industry standard for powerful musical expression, featuring sound engines that inspire musicians to create and perform. Pa5X introduces the EDS-XP (Enhanced Definition Synthesis – Expanded) sound-engine, which builds upon the technology used in Pa4X with advanced hardware and a powerful new operating system, taking sounds on Pa5X to a new level. The 24 stereo Oscillators and 160 voices of polyphony power thousands of high-quality sounds, covering a wide range of musical instruments and genres. The EDS-XP sound engine also introduces new cutting-edge features such as Round-Robin drum and percussion performance, Smooth Sound Transition, Sound-Controller 3 functionality and much more. This provides an unprecedented level of sonic realism and expression that is only available on Pa5X.

Realtime Controllers

Pa5X features a fully programmable control section with 9 buttons and 9 sliders. You can assign any function to it, from mixer volume to drawbar settings, from microphone mute to bass inversion, to lyrics scroll commands and more. The assigned function is shown by an auxiliary strip display so that you always know what you have under your fingertips – even if you are on a different page to the main display.

Numerous assignable controllers are available for expressive real time playing and Korg's DNC (Defined Nuance Control) which supplies so much of the detail in the sound of musical instruments. Faders, switches, real and virtual matrices of real time controls, the joystick, and the ribbon controller can be assigned to modulate any parameter of the sound. This provides precise control of the most subtle nuances and articulation of the instruments you are playing on the Pa5X.

Advanced Chord Recognition System and Full Library of Chord Sequences

Pa5X’s chord recognition system is the most sophisticated around, featuring an Expert mode that is crafted around the playing styles of the best modern jazz pianists. This chord recognition system can be as simple or advanced as desired, even allowing you to trigger chords with a single finger!

With automatic harmonization, a chord sequencer, and a sophisticated chord recognition engine, Pa5X gives you the tools to create rich musical arrangements no matter what the genre of music.

Dedicated Microphone and Guitar Inputs with Effects Processing

A microphone and a guitar can be connected simultaneously to the separate audio inputs of Pa5X. KORG’s extensive experience in vocal harmonization technology and guitar effects processing is featured, with each of these inputs having dedicated on-board effects.

We are proud to have teamed with Shift Audio, a company with 30 years of experience in vocal processing technology. The founders of Shift Audio came from an industry leading company specializing in vocal processing products building on their experience to deliver. The latest generation of vocal processing algorithms optimized to run on the latest technology used in the Pa5X.

The result is incredible lifelike four-voice harmonies that give you the feeling of a real singing group surrounded by your own music. You will also enjoy the new Auto Pitch feature in the Pa5X delivering performance and sound found in a lot of modern music.

The separate guitar input is completely independent and even has its own gain control. Guitar effects include vintage pedal and amplifier simulators to enhance your guitar sound and performance. There are many predefined guitar-presets of up to 4 insert-effects provided, and it is also easy to create and save user effects presets. These new powerful guitar effects make the live performance of your guitarist much easier, as all the effects and effect-settings are handled by the Pa5X. One vocal and one guitar-preset can be assigned to each SongBook entry which makes for an easy and fast musical performance.
