Hi Everybody,
There is a new update for your Korg PA5X to take it to 1.4.3
You can find it here
https://www.korg.com/us/support/download/software/0/895/4965/

Best Regards,
Barry

Brilliant,
Many thabks for letting me know.
Enjoy that Pa5X. It is unique.
Best regards,
Barry.

Thank you Barry, that is most helpful. It is now working correctly.

Hi There,
Sorry I have not been on for a couple of days.
Sorry also to read that you have Parkinson's.

Please ensure that you have the main volumes on the Nautilus and the PA5X turned right down before you start this.

OK have you turned the line inputs on because when you first turn the Pa5X they are disabled.
The instructions for that are on Page 700 of the Pa5X_User_Manual_v1.4_(English).pdf
Please make sure that you follow the instructions re lowering the Volume level to zero before you begin.
This is what the Manual says

Turning the line channel on/off
1
Be sure the selected CONTROL mode is MAIN.
2 Use BUTTON #5 (Line On/Off) to turn the line input channel on or off.
Please note that, for safety reasons, the input is always switched off when turning
the instrument on.

Adjusting Slider 5 of the Control section changes the volumes.

Again this is what the Manual says on page 704

Line Audio Inputs
Adjusting the line channel volume
The line input can be quickly turned on or off, and its volume in the mix adjusted,
right from the control panel or from the main page.
1
Be sure the Line channel is turned on.
2 Be sure the selected CONTROL mode is MAIN.
3 Use SLIDER #5 (Line) to adjust the Line channel volume.

I hope that helps,
Barry.

I hope that you can help me. I am a novice keyboard player with a disability. I have Parkinson's disease and I purchased my Korg Pa5x a few years ago to enable me to enjoy playing the keyboard for my mental health.
The Pa5x is an excellent machine, and I have hardly explored all the functionality that it offers me.
I decided to buy second hand a Korg Nautilus 73 to explore the functions of a workstation.
I have installed the Nautilus workstation on a two tier keyboard stand, and I bought some cables which I thought I would use to plug my Nautilus into the Pa5x and then I would be able to hear my Nautilus sound on my PaAS speaker
I first used 1/4 inch mono jack leads which I connected to the Audio out L & R jack sockets on my Nautilus and to the Audio In L&R jack sockets on my Pa5x.
I could not hear any sound on the PaAS speaker. The Pa5x was powered up, but I could not find out how to enable the Audio In sockets on my Pa5x to be able to hear the Nautilus sound.
I had also bought 3 midi cables. Please note that I am not familiar with MIDI function, but I thought I would plug in the OUT socket on the Nautilus into the IN socket of the Pa5x.
I then thought that I would plug in the other two MIDI cables to the IN/OUT sockets which remained and the THROUGH socket too.
I heard sound but it was not the full sound which I could hear on headphones connected to the Nautilus.

Can you please provide me with some simple instructions which would allow me to hear the full sound of the Nautilus on the Pa5x PaAS speaker?
I can see a large number of options in the MIDI menu, but I don't have enough understanding to competently troubleshoot.
My current view is that what I am trying to do is not supported between the two keyboards, and that I may need to buy an external mixing desk and connect that to an external amplifier and speakers in order to hear both the Nautilus and the Pa5X sound.
I hope that you are able to help me.

Hi There Susan,
Many thanks for your message and I am so sorry for the delay in getting back to you.
I have just checked the page and it does seem to be loading OK. Not fast but OK.
Have a wonderful New Year,
Barry.

Hi there Korg Fans,
The new update is version 1.4.2

Inside the update zip file you will find a 280 page PDF of new features and improvements. Please read the instructions carefully before putting applying the update.

Hi There James,
It is really great to hear from you.
What a wonderful article this is.
Many thanks for posting it and for your contribution.
Best Regards,
Barry.

The Pa5X is a powerful workstation, but there's one modern tool missing that would truly elevate its creative potential:
a built-in MIDI-FX step sequencer, similar in concept to Woodpekr.

Not an audio loop tool.
Not just an arpeggiator.
Not a pattern sequencer buried in the style editor.

I'm talking about a realtime MIDI generator/modulator that sits in the MIDI-FX chain and can output:
   •   Notes
   •   CC automation
   •   NRPN data
   •   Probability-based rhythms
   •   Step-locked modulation patterns

✅ Why this matters

Arrangers traditionally rely on pre-built style patterns, but today's production workflows demand:
   •   Real-time pattern creation
   •   Automation inside the keyboard
   •   Probability, ratcheting, step gating
   •   DAW-style modulation lanes
   •   Euclidean and polyrhythmic sequencing

Modern producers expect this from software and modular gear — there's no reason a flagship workstation shouldn't offer the same power.

✅ What it should do

A Pa-series MIDI-FX step sequencer should include:
   •   1–64 steps
   •   Per-step note, velocity, gate, probability
   •   Per-step CC/NRPN lane
   •   Ratchets/micro-steps
   •   Pattern chaining & save/recall
   •   Sync to style/song tempo
   •   Assignable per-track (Upper, Lower, Drums ch.10, Pads)
   •   Option to send to external MIDI gear

In other words:

A Step Modulator for the Pa workstation that turns MIDI into a creative engine — not just playback data.

✅ Why Korg is positioned to do it

Korg already has:
   •   DNC articulation
   •   Style engines
   •   Scene/variation switching
   •   Advanced MIDI routing
   •   Processing power and UI for deeper MIDI tools

This feature isn't a stretch — it's the natural evolution of an arranger into a modern hybrid workstation.

🎯 What this would unlock
   •   Live pattern manipulation
   •   Intelligent fills beyond fixed styles
   •   Modular-like creativity inside the keyboard
   •   DAW-level automation without a computer
   •   More expressive, dynamic accompaniment

A MIDI-FX sequencer on the Pa platform would be a game-changer — giving users a creative tool that bridges traditional arranger workflow with next-generation electronic music and film-score style sequencing.

Korg has always innovated. This is the next step.

Final Thought

A $6,000 flagship should feel like a 21st-century creative instrument, not a closed environment.

Adding a MIDI-FX step sequencer would not just catch up with modern production — it would put the Pa platform ahead of the curve.
