Library Files and Piano Manager

Let me first say that I have two AccuTuner IV “980’s.   I have two because I don’t want to work without one.   I alternate them , using one for one week and the other for the next.   I also use a Microsoft Surface Pro 4 when I tune.   I have two of those as well.   I’m backed up, with both hardware and software.   It’s a great feeling to know that if one of my SAT’s go down, or one of my Surface Pros go down, I’m still tuning as usual with no stress.

I can experiment with a SAT pretty much as much as I want, because if even if I mess it up, I can still go tune using my working combo.   Both of my SAT’s are exactly the same, and I have pretty much exactly the same tunings in both.   They are interchangeable.   The Surface Pros are both Windows 10, both have Excel, Piano Manager, and whatever other applications I need to tune a piano.   The Surface Pros are not exactly the same, however.   I bot a little more than I needed when I bot the first one, so when I bot the 2nd one, I got it with a slightly smaller SSD drive, and a slightly lower CPU.   But both work great for a portable fast device I can carry with me every day.

Backups are a very ‘freeing’ feeling.   I’m fearless, knowing almost whatever I do, I will still be able to work.

I say that because when working with Piano Manager, especially when working with the Extended Memory, reading and writing files to the SAT IV “980”, there have been times when files have become corrupted.   If I only had one SAT, I’d probably get freaked out.   But since I’m backed up hardware-wise, I can calmly keep working with the program and the SAT until I get everything working smoothly and how I want it.

Piano Manager is a relatively new piece of Software, and the SAT “980” is a relatively new piece of hardware – in fact the “980” has only been available since late 2016.   There have been numerous updates to the Piano Manager program, and again, I’d recommend using the latest version.   You can download it here.

Library Files or .LIB files are the type of files used by the Sanderson AccuTuner IV’s ‘Extended’ Memory.  This upper memory or ‘Extended’ memory greatly expands the capacity – the number of tunings – that can be stored in the SAT IV.

With a SAT IV, when installing, retrieving, sending, reading, or viewing tuning files in the SAT IV’s upper memory, .LIB files are used.

However, these .LIB files used by the Extended memory require a slightly differently ‘handling’ than the .SAT files used in the ‘lower’ memory of the SAT IV.

The .SAT files are the file type that has always been used in the earlier model AccuTuners:  The SAT II and SAT III.   So, if you connected your SAT II or SAT III to a computer (via MIDI connections), you were working with .SAT files.

But the SAT IV “980” uses both .SAT and .LIB files types for memory storage.   The .SAT file format is used for the ‘lower’ memory (Pgs. 1 – 140) and .LIB files for the Extended Memory (Pgs. 141- 980).

The Standard Model SAT IV  also uses both .SAT and .LIB files types for memory storage.   The .SAT file format is used for the ‘lower’ memory (Pgs. 1 – 140) and .LIB files for the Extended Memory (Pgs. 310 – 589).
{The Standard Model SAT IV has a protected area of it’s Extended memory that is used for Inventronics Memory Tunings.   The tunings in that ‘protected’ area cannot be changed, moved, edited, or addressed in any way in Piano Manager}.   

When using Piano Manager to organize, read/write, send/get, tunings from the Extended memory of either standard SAT IV or SAT IV “980”,  .LIB files are used.
When using Piano Manager to organize, read/write, send/get, tunings from the Lower memory of either standard SAT IV or SAT IV “980”,  .SAT files are used.

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 “980” and Standard Model SAT IVs, the memory is organized in what can be called ‘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 it’s that bank that requires a .SAT file.

The SAT “980”s Extended memory, which begins on Page 141 and ends on Page 980, is divided into 6 banks, with each bank containing 140 pages.   Each ‘Bank’ of 140 pages of the extended memory needs to be addressed individually.

So, to fill up the upper memory of a SAT “980”,  six .LIB files, each with 140 pages, are used.
To fill up the upper memory of a Standard Model SAT IV, two .LIB files, each with 140 pages, are used.

The Standard Model SAT IV works just the same, but instead of the User available pages starting on page 141, they start at page 310.   That gap – between page 141 and 309 – is the ‘protected memory’ space used by the Inventronics Pre-Stored Memory Tunings.  By Pre-Stored, I mean 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.} 

The Standard Model SAT IV’s pages 310 – 589 is actually two banks of 140 pages each.
So, with the Standard Model, two .LIB files will be used – 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 SAT is plugged in to the computer.

When Piano Manager recognizes a Standard Model, when clicking the Xmem button, you will see the send and read choices and then the 2 banks with their pages 310 – 449, and pages 450 – 589 in Piano Manager.

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”:

(If yours is a Standard Model, you will see the two options, one for pages 310 – 449, and one for pages 450 – 589).

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 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.
