Reading this post is a good preparation before watching the 25 minute video linked below.
The SAT IV uses two different file ‘types’ for memory tuning storage.
The older SAT IIs and IIIs, didn’t have ‘extended’ memory, so they are able to get along with just one large file for memory tunings.
But the memory of the SAT IV has been expanded to more than double that of the SAT III, requires a different file type for the additional memory. The SAT IV’s extended memory uses library (.lib) files.
The ‘lower’ memory (Pgs. 1 – 140) in the SAT IV “980” still use the .sat file type format, but the rest of the pages (Pgs. 141- 980) need the .lib file type.
{SAT “980”: .sat file for the first 140 pages, and .lib files for pages 141-980.
SAT IV “Standard Model”: .SAT file for the first 140 pages, .LIB files for pages 310 – 589.}
In both SAT IV models, the memory is organized in ‘Banks’ of pages. Each ‘Bank’ contains 140 pages.
The SAT “980” has a single bank of 140 pages that makes up the lower memory, and that bank requires a .SAT file.
The Extended memory, which begins on Page 141 and ends on Page 980, is divided into 6 individual banks of tunings, with each bank containing 140 pages each. Each ‘Bank’ of 140 pages of the extended memory needs to be addressed individually and uses .lib file types..
The memory of both Standard SAT IV and the SAT IV 980 works just the same, there are just fewer ‘banks’ in the standard SAT IV. Instead of the “User available” pages starting on page 141, they start at page 310. That Standard SAT IV ‘gap’ between page 141 and 309 is the ‘protected memory’ space used by the Inventronics Generics Pre-Stored Memory Tunings. These are the built in tunings that come with the Standard Model SAT IV.
{These same Inventronics tunings can also come pre-stored in a SAT “980” if desired. But with the “980” they are stored on pages in the Extended Memory that is available for us to use and not protected by the SAT’s program. Those Inventronics Tunings can therefore be organized differently, or modified to suit the needs and wants and uses of the SAT Technician. They can also be erased or written over to make room for other tunings.}
In the Standard Model SAT IV’s pages 310 – 589 is actually two banks of 140 pages each – two .lib files – one for bank 310 – 449 and another for bank 450 – 389.
Working with .LIB and .SAT files in Piano Manager for both SAT IV models is exactly the same.
Piano Manager recognizes which model (Standard or 980) SAT is plugged in to the computer.
When clicking the Xmem button, the send and read choices and then the number of banks with their pages 310 – 449, and pages 450 – 589 will appear in Piano Manager.
(Since I don’t have a standard model SAT IV, I can’t show a picture of what that looks like. But it’s just like the picture below, only with different bank information. If yours is a Standard Model, you will see the two options, one for pages 310 – 449, and one for pages 450 – 589).).
With a SAT “980” instead of the 2 banks with their pages 310 – 449 and 450 – 589, Piano Manager shows the 6 banks, named Bank 1, Bank 2, Bank 3 and so on.
With either Standard or “980” each bank must be dealt with individually in Piano Manager.
Here is what Piano Manager’s Xmem tab shows when connected to a SAT “980”:

Of course, after the banks and pages of tunings have been installed into either model SAT IV, scrolling up thru the pages in the extended memory is seamless, the SAT reads the banks as if it was all one file.
This 25 minute video will show how to use and work with Library files in Piano Manager for storing and retrieving tunings in the Extended memory of the SAT IV.
Some of the basic differences between a .sat file and a .lib file will be explained.
Also shown in this video is how to move a single tuning or a group of tunings from one tuning file to another. Tunings can be moved from a .SAT file to a .LIB file and vice versa.
