Hi, i have a montage 6 for a couple of years, only at home use, but for some time now, the touch screen is not responding at (usual) the outer edges when tapped on selections,
even with the calibration screen the 2 lower edges of the screen wont respond as good as it should, i have to tap the lower 2 dots several times, to get them to respond.

That seems consistent… the Calibration screen is used to recalibrate normal operation. Not responding to the outer edges is what is being recalibrated. If the dots were initially spot on, you would likely not be on the calibration screen in the first place. Tapping the dots several times may indeed be necessary to recalibrate the screen.

Press [UTILITY] + [COMMON] > then [ENTER] to launch screen calibration using buttons.

You should do so whenever necessary. The fact that you also report that after you’ve been using the unit for an hour it doesn’t happen any more — we assume this is after you have successfully recalibrated the screen. If after an hour it fixed itself (without you recalibrating it) that would be something maybe… but recalibration, when successful, is not measured by how many times you have to hit the pixel… it is measured by the last time you tap the pixel and it offers you the next one to tap.

I’m simply saying, there is nothing unusual about tapping that dot and getting no response, if that happens, tap it again until it disappears. It disappearing means it is now recalibrated.

If you’re asking why it gets askew, I couldn’t tell you. But everything you have reported seems like a normal recalibration. I’m guessing temperature might be one of the things that affects screen behavior — next time I talk with a technician, I’ll see if they have any additional information.

Thanks, for the reply, this behaviour, of the touch screen, it does it every time i switch on, even in the re cllibration screen, i have to tap the lower dots several times,
and when i complete the calibration, it does not improve, until the unit is on for about one hour, so yes it is like it has to 'warm up' or something, that seems a bit weird.
Anyway its a bit of a nuisance, that it wont repond as snappy right away, as it used to do in the past, eventually i might take it to the store where i bought it, to get it fixed,
no rus, cause its probably no warrenty, since i have it for about 2 or 3 years now.

Interesting that this is happening in the Montage now. I had a similar problem with a MODX7 earlier this year and it's still continuing intermittently. The lower "buttons" on the screen were not accessible-the touch points were off the touch screen. "Run the recalibration": well that only works if the dots respond and in my case the top two responded but the lower right never did, however many taps or however long I waited. Recently I was out of town for a week and then a hurricane was threatening so the MODX was unplugged for about 3 weeks. When I powered it up again there was no response from the touch screen. I could still use the hardware buttons to select sounds but can't access the "buttons" on the far left of the screen with the hardware buttons. After leaving the board on for an hour or so the screen finally responded but again, not to the calibration routine. Lately it seems to be working again. It's about 18 months old so out of warranty, it doesn't leave the house, and as with most intermittent problems if I take it to the local service center it will probably work fine for them. In an internet search I found I'm not the only one with this screen problem. Hardware issue? Software issue?

I have the problem you mention. A few days ago I took my Montage 8 to a stage and the temperature was very cold, suddenly I noticed that the touch screen was unresponsive and operated only on the left side. While starting the show I selected the voices with the buttons on the right, but the screen continued with that behavior, then I had to enter a different menu so that the voice would not change automatically. After a moment, I assume that due to temperature increase it normalized. However, on a second occasion, in a different, colder scenario it never worked properly and I had to play my entire session with a piano. On returning home I installed the piano in its usual place and it was operating normally. I consider this a bug that Yamaha should correct because something is wrong with low temperatures.

I've had problems with Yamaha's display flex (or more rarely: ribbon) cable connectors from flagship synths to consumer relatively lower cost pianos.  They seem to be sensitive to humidity and/or temperature.  Almost wish they would solder down a ribbon cable - not make it a flex cable - not make it removable for service.  Then come out with the removable part as a USB connection or more robust cabling in general.  

With Montage - you should be able to navigate everywhere you need with just physical buttons and without having to touch the screen to select things.  This takes some learning how to use the cluster of buttons to the right of the screen in order to navigate around.

And then the other part of this would be - so you don't have to memorize how to get around - is to carry with you a small monitor you could mount somewhere and connect with a USB cable and USB-to-video converter that's compatible with your monitor and Montage.  There's other threads on this.

That's one backup plan.   The other backup plan would be to use a tablet or laptop to "tell" Montage (using MIDI) to change to this or that Performance or Live Set slot.  You would just be driving by using the computer/tablet device to get you through the night.  Probably overall this would be much much easier to setup and carry and just figure out in the first place.   I've got an old iPad I carry with me and I did purchase Camelot Pro which could serve as the software to organize my set list on the tablet.  There are free options too.  Soundmondo can be used offline for this using an iPad.  Android or Mac/Win laptops have their own options of varying expense (including no cost).

Given this seems to be an achilles heel going back generations - I don't see this getting fixed anytime soon.  Maybe add an idea to ideascale and see who can rally around it.  I'd be happy to upvote and add my thoughts.   Therefore, for now I would suggest managing the potential for this happening again with one of the options given.   

I guess another route would be to use some kind of foot pedal that can be programmed to pull up any Performances or Live Set slots you want.  It may be more limited in terms of how many different - lets just call them "patches" to generalize - you can recall with foot presses.
