This is some of what is being posted on Korg forum:

After a few days of using PA4x found so far several bugs/problems:

1.Pads are locked in Global,and saved 4 constant pads on " My setting" for start up ,but,after restart, these pads are not the ones selected and memorized,and volume- eq -fx values ,too. - Conclusion - Pad lock function does not working properly.

2.No individual Songbook entry delete option (only initialize Songbook option - wipes whole Songbook )

3.Can not write current style/kbd set/voice preset in Songbook (Book Edit 1 - Write current ) if other style is selected for that song. It can be only saved as new song

4. Voice preset lock option is missing. Voice preset randomly goes on user preset 1 when changing kbd set. There is "Global" check box in Mic tab on main menu screen but after changing style , that Global checkbox always reset to "checked"

5.Found compatibility issues -pa3x styles to pa4- some parameters pa4x did not loaded exactly as they were in pa3x ( Mixer - master fx values for some styles)

6. Compatibility issues with converting Pa3x performances to Pa4x keyboard set - some parameters did not load exactly as they were on pa3x (Master FX values in Mixer menu)

7.Tried to delete random style in Direct style SET which is located on storage internal labeled "DISK" (KORG DISK) and style couldn't be deleted, says "device generic error" . Worked after keyboard restart.

8.Scroling Effect with finger is randomly working, most of the tries and time doesn't work ... Searching for right Insert FX is not easy now...Only work fine when listing effects with wheel ,touch is not working properly .

9. Display font and graphics are not sharp, very bad feeling for my eyes. I am wearing glasses and this is not very pleasant experience,especially when we do not have Songbook editor,styles are not loaded correctly from previous models (explained above) and I spending now hours with Pa4x watching in that display...Not convenient at all.


That's it for now,after 2 days effective usage...Probably will find more. Waiting for new and improved OS

MIDI to MP3 recording to storage KORG HD at 126 BPM MP3 was recorded up to 23 measure. As if the recording starts after 23 measures. While the recording was started first and then play midi !!

MP3 song is not complete. Missing 00:00 to 00:38 seconds!

I'm sure most if not all, plus other problems will be addressed in OS update. It won't take as long as the Ketron update.

Don thanx for sharing this.....I Know as in the past KORG is on the case big time to fix these and what ever comes up in the future ASAP...but, what I want to know is why don't they do more extensive testing before release instead of having the buyers find all these bugs and become the Guinea pigs?

That's a great question!

Donny, my sentiments exactly! A lot of us are performing in front of live audiences and don't have the luxury of do a "reset" while the dance floor is packed etc.

I have to say for the most part thru the years YAMAHA Arranger KB's have held up gig after gig with outstanding performance.

I never had a Yamaha arranger keyboard fail at any time. Thousands of jobs, thousands of moves in and out of the van, setting up and tearing down and never experienced a single hiccup. That's one Hell of a track record.

Well, you all have short memories. I've never any a Korg or Roland fail either, but plenty of hiccups on all brands, including Yamaha.
They had VH parameters wrong on the PSR2000 and never corrected them, although they emailed a full-page work-around so you could sort of make it work as it was supposed to.
They had multiple screen failures with PSR S900.
I can dig up more, but I remember these right off.

You're right, my memory is shot to Hell, and back when I was using the PSR-2000 I didn't use their vocal processor because it didn't sound nearly as good as the Digitech VR that I purchased from one of the synthzone members.

The more complex something is, the more difficult it is to isolate bugs. (Windows 10 had over 5 million testers over 8 months (Not including the Microsoft development team) to iron out any bugs before launch, yet there were still some users that had initial problems with it, which required updates to fix)

One of the reasons medical and military equipment is so expensive is because of the amount of time taken to test, however I doubt many keyboard owners would want to spend 10 times the amount they already pay for a keyboard just to guarantee everything is totally spot on at launch.

Bill

Don, Thanks for posting those bugs!






Donny, From what I've seen some tech companies have a tendency to rush products to market it's all about he bottom line, not sure about Korg................but....... slow to market equals lost sales, especially going into November and December.
