I totally agree. In fact, not only quantizing but the selection whether synchronizing in a performance should be external (I/O | midi) or internal clock should also be stored in the performance. A global default setting is fine, but within a performance overriding (and storing that setting) should be an available option.

Agreed. I'm just starting to dig-in to this machine and have to say that there needs to be some rearrangement and more thoughtfulness in Navigation.
It is a bit messy, unnecessarily complicated. It's too old school Japanese.

Err, before you go off on a rant...

Sync Quantize settings: Not memorized Globally. In fact it always remains OFF
Must we have to set these parameters in the utility page, rather than where it shoud be- within the performance?
Please consider making parameter settings in the Utility page Global but, providing a entry within the performance pages when one wishes to over-ride the Global.
Settings that are effective specifically for each Performance MUST be located within the Perfomance

The "Auto Sync Quantize" parameter is found in each Performance.

Press [EDIT]
Press [COMMON]
Touch "Arpeggio" > "Common"

In fact, as you spend more time with Montage you will realize that the setting you see in UTILITY mode is just a repeat of the current setting in your current Performance. They are one and the same parameter repeated for your convenience on the page with all things you would or might need when setting TEMPO (MIDI SYNC, ARP SYNC QUANTIZE, CLICK, etc., etc., etc.

It's a feature! (What does it have to do with being Japanese? Curious thing to say)

Very useful solution

I understand nothing -

In Utility mode, the sync function isn't memorized Globally. For me and probably many others, the choice made there is more likely to be in force the majority of time. One only need change it perhaps, 'here and there' so, allowing one to have it available per performance just means that we need to constantly change it. We need both Global and performance.
Regarding 'tempo function'. Most digital audio processors that I've worked with, where tempo is a major feature, provide a global tempo and a per-patch/program/performance tempo. This is very, very necessary. Montage/motif and I assume many other Yamaha devices do not, why not? Regarding tempo, the panel button labeled tempo, how does it work? When I am in performance mode, I can't tap on that, it produces paging but not tempo updates. How does it function.
About old school Japanese. Having observed decades of Japanese manufacturers of digital, menu/page driven, musical/audio products, there is and has been a typical approach and style to it which is generally lacking in clear, well implemented navigation. This is also reflected in owner's and reference manuals. We all know how these are viewed.

... "panel button labeled tempo"

Let me see if I follow. When I:

1) Press the [UTILITY] button
2) Touchscreen (TS): touch-select the "Tempo Settings" left-hand menu option

Alternatively, there's a faster way to get here which is in the top line of the display - there are a series of icons on the right-hand of the top line which shows "FX" (a quick touch icon for getting to the effects menu), icons of keyboard next to the current MIDI mode (USB or DIN) which touching this "quick touch" icon pair brings up the "quick setup" menu, then an icon of a quarter note next to a number - which is the current tempo. You can touch this tempo "quick touch" icon area to transport you to the above menu which otherwise would take an extra step of pressing the [UTILITY] button first.

Either of these methods brings me to a screen that shows a touchscreen field "Tempo" which displays the current tempo setting and also allows for manually entering the tempo.

One item I'm struggling with is your use of "performance mode". Since the keyboard is always in performance mode - this has a nuanced meaning when you use it which is not clear. I can infer you mean that when this screen is not displayed - there's not a way to edit the tempo assuming you have the MIDI sync set to internal. Maybe this is not what you mean.

If you have Sync/MIDI Sync set to MIDI or A/D IN - then these are external sources of the tempo and therefore would not provide a provision to edit these through parameters.

I'm intentionally squelching my feedback (previously given) for tempo since I'm more trying to understand what you're communicating instead of just "riding on top" of your post.

Hi Jason. There is a physical button on the front panel labeled Enter/Tap Tempo. Not unexpectedly, One might assume that we should "TAP" the Tap Tempo button, NO?
I am aware of the on screen methods you've pointed out, thanks.
Regarding performance mode, sure its possible to not be seeing the home page. I do understand that when we are in Cat search we are more or less in performance mode but, AFAIK some functionality differences exist regarding accessing button actuated arps in cat search versus home, etc. When in record mode, again, being able to TAP a button labeled tempo tab SHOULD update tempo, NO?
Global tempo is very important as is evidenced by the overwhelming number of examples of it's use across the industry. Montage should offer global tempo, as well, per-performance and also in Sync Quantize.
