Hi Keith.
Being a retired MF storage specialist for 46 years has embedded Backup/Redundancy/Recovery in my brain and it is second nature for me to backup up everything. In fact I clone 4 USB sticks and when I change the LIVE USB1 on the keyboard, I fire up the others one at a time and copy any thing that was added/changed to the others. Crazy, maybe. But the beauty is that I can grab any one of these sticks and put them into my keyboard or any other keyboard(done that already) and they "work" fine.
The copies on the computer when I tested them by putting them on a stick and tried to use them did "not" work for me. They behave the same way as moving things around like registrations from one folder to another or renaming a folder, the path to the necessary registration components are lost. Unless the Registration is using ONLY what is loaded on the keyboard, then they work fine.
To your point of perhaps keeping them taking them off the "USER" memory, now that I think about does make sense because if I don't load any of my USBs and try to use the ones in memory for example a Registration needs resources from a source other than what is loaded on the keyboard, the Registrations will not work. When I fire up the same Registration with any one of my USB sticks everything works fine.
My searches however are done with one or even all of my stick loaded(favor of the moment) at times, so when I sync my sticks I may have them all connected, USB1,2,3 & 4. While in this state if I search something that has shown up in the past as I stated previously, they will always be found with no problem. Yes it may take the search a little long but they do come up and work.
I have a previous post where Chris made recommendations on my setup with multiple USBs loaded at the same time, so I kind of understand what I can be up against in that first search scenario but been running okay till now. Note that once in a while the search request can pop up a window with the word "Checking" in it when things take a little longer than they should, but at the end I get my results.
As for the Expansion Pack, I got that free from the Yamaha website late last year and only starting to paly with my Packs now. Not sure if the S770 in the name has something to do with my second behavior perhaps meaning that the pack is designed for the S770 and using it on the SX700 may not work as expected and I just have to accept what works for it and what does not?
However, I would still need to understand fully why it takes so long for the keyboard to recognize new entries on the USB. It must have some odd save/search algorithm.
Thanks for your feedback, but I am curious about your backup strategy. If you were to get a new stick and only put some of your Windows backed up files on it and then tried to play say a registration if it would work, keeping in mind that you pick one that does not required ONLY the resources that are loaded on you keyboard. Meaning, that a style in that registration resides in a folder that is/was on your USB at the time the registration was created. In my case I have over 25,000 styles and of course they are not on the keyboard so I have to depend on my folders on my USB sticks. Give it a try and let me know.
PS: FYI.
https://www.psrtutorial.com/forum/index.php/topic,60280.msg464350.html#msg464350 I have read this and with my fully loaded USBs, regardless of what I have on them, my search
for old existing files is fine as mentioned above where it can take some time to find or go into
checking mode with the pop up window but it gives results within less than 3 minutes" . It's only
the new stuff that takes it's time to appear.
Note:
I also forgot to mention that this issues pertains ONLY to new stuff in folders. If I save outside folders I have no issue with the search. It finds the file within 1-2 minutes. My USB sticks contain 21gb of data on them. I did a test with a USB containing many duplicate files pushing it to 45gb on a 64gb USB and still had no issues with the search of old existing files. So my final conclusion and observation on how much is loaded on a stick is that size does not hurt me, yes as Chris mentioned in the attached post, the keyboard is overwhelmed, but it does work over tme very well if you are patient with it and know what to expect.
Best regards.
