yes that may be ok.....but try doing that while singing a song lets say and your doing the eg: the big "MY WAY" etc, Ending and it locks up...OMG!!

I had a new Roland E-70 many, many moons ago, that would lock the left hand sound on the last chord played, with the new chord only changing thew style. It was totally a random thing. The only way to stop it, was turning the instrument off, and back on. I was working at a music store in Newfoundland, so I sent the keyboard back to Roland Canada, and it was replaced with a new one. The second one worked perfectly.

This was in the days before OS upgrades could be user installed.

Outstanding service by Roland Canada, but at the time, the glitch was very irritating, as are all random problems.

I hope this issue with Dave's PA-900 can be rectified as soon as possible, as, like Donny said, it doesn't give you a very secure feeling knowing it can happen at any time.

Stuck notes, while being pretty rare (I've only had it happen twice in ten years - and, ideally, shouldn't happen at all, but it's not an ideal world), what are the realistic odds of it occurring at a crucial point such as you mention, Donny? It must be one in billions.

You can, with cool judgement and good timing, make it unnoticeable by hitting a dead stop at an appropriate point and utilising that as if it were intended. Even if it did occur in the '"big ending", you could still pull it off.

It was most likely inhabited by some sort of spook during the Halloween party. Perhaps you could get Deacon Fran of the great Church of Roland to say a few words over it.

Thing is, what's the buzz over at Korgforums about this issue? I would have thought that's the place to find out if this is common, if there's a repeatable way to produce it (hard to get action from Korg until you can spell the problem out in a way they can get it for themselves), and whether anyone has figured out a workaround.

From having run the Roland-Arranger.com Bug Forums for some years, my experience is that the more information you can give them to reproduce the bug, the better your chances of them taking it seriously and fixing it. So, I know it's bit of a chore, but if you can write down quickly as much as you can remember from any lockup happening, the style used, the Performance, the Songbook entry, RH sounds, and then what you were trying to do, with any luck and a bit of perseverance, you can get it to happen again at home.

Once you have a repeatable bug, the manufacturers take you FAR more seriously, and a fix should be coming, with any luck, or at least a workaround.

The thing is, most of our modern arrangers have Songbooks, Performance Lists, MusicFinders, etc.. and fully using these can save you a ton of button pushing between (and during) songs. If that's the issue (too rapid button pushing), making full use of these features should cut back on the need to do that so much. Many of us came from the 'Free Panel' days, and still tend to do much that way, but more modern ways now exist, at the cost of more preparation at home.

If a fix doesn't appear quickly, perhaps using these more fully can help?

Thanx for all your input, but I may not have described the issue correctly - the sound emitted is NOT a stuck note - it's an electrical drone signal and it's the same pitch each time.
More thoughts came to me from your many comments ...

I will take out the "freebie" styles that are not native to the PA series(they didn't work perfectly anyway), and I will reformat my USB drive for starters.

This lockup is not the same as a note freeze - the instrument is rendered useless and must be powered down to proceed. Mic shuts off sound blares until powered down.
A puzzlement, for sure.

Dave,

That is an OS crash for sure and it is very likely one of the things you have loaded into the keyboard from outside source or defective USB device.

You're on the right track and please keep us informed of your progress because we too have this keyboard.

Dave ... how did you make out with this problem?

This is the same lockup they had with the PA2X which drove me crazy and into a T4

If it is so hard to find a repro, it can't be all that common...

You say it happened only three times. In how many performances? And you can't make it happen at home?

I think one of the things I'd suggest you try is a small, inexpensive UPS. House power can vary radically, not just from venue to venue, but at different times. If, for instance, the house A/C and the house freezers/walk-in fridges all power up at the same time, the power browns out a bit, and that's not something you are likely to ever encounter again.

On the whole, a UPS is the first thing I'd try. If you can't get it to lock up at home with a whole bunch of button pushing, it may not be the issue. But a whole lot of different things, from computers, to DVR's, to modems etc. can be VERY intolerant of drops in voltage. $30-40 ought to be enough to get one, and even if it doesn't cure this particular problem, you can still use it at home for your rig there...
