SAT IV Users:

The SAT IV has more than double the memory of the earlier SATs.  This extra memory results in a different memory configuration within the SAT IV.   Piano Librarian treats the extra memory in a different way.

In the older SAT IIIs, there was a memory space that would hold 198 tunings.    All tunings went into that single space and were handled as a single file of single block of tunings.     The SAT IV is different.

The SAT IV actually has 4 separate memory ‘areas’ or spaces, for 4 groups of tunings.

Pages 1-120 are exactly like the older SAT IIIs.  They can be written to or written over, and can be saved to a file, and sent to the Piano Librarian Program.

Pages 121 – 140 contain special pages used for storing sequences, temperaments, custom pitch raise amounts, Exam pages, and so on.

Pages 141-309 contain tunings provided by Inventronics.  These pages with Inventronics tunings, are ‘protected’ and cannot be over written.  We can ‘copy and paste’ them to a page (1-120), and do a few other things with them,  but the Inventronics tunings in their original form cannot be lost, altered,  written over, or damaged.

Pages 310-589 are available pages of memory for us to use.   These pages are ‘write only’.   If I have a .lib  file, I can send it, or write it, to those pages in upper memory.  But, the SAT IV cannot ‘send’ an upper memory file back into Piano Librarian.  All work on the .lib tunings:  the creating, sorting, organizing, arranging, naming, saving, &c., is done within Piano Librarian.  The file is then then installed into the SAT IV’s upper memory, replacing whatever was previously on those pages.

For our purposes here, we are only interested in the areas of the SAT IV”s memory we can write to and use: Pages 1-120, and Pages 310-589.

The ‘lower’ memory of the SAT IV is similar to the older SATs and will hold 120 tunings and uses the same file format as the older SATs.

The ‘upper’ memory, pages #310-589,  as previously noted, must be handled slightly differently than the lower memory. For installing tunings to this upper memory area, the tuning file needs to be 140 pages or less and be in the .lib file format.  Piano Librarian’s (library) format “. lib” is used when storing pianos to these upper memory pages.

Both these file formats: .sat, and .lib, are part of the Piano Librarian Software.

If you have had your SAT IV for a while and are just now wanting to use Piano Librarian to manage your tunings and communicate with your SAT IV, before you get started, it might be a good idea to contact Inventronics to make sure you have the latest version of Piano Librarian, and the latest firmware installed in your SAT IV.

Also, please please please backup your Accu-Tuner files as you would your other important files.   Make sure to include your .sat and .lib files in your automatic daily backup routines.  Also when working on .sat and .lib files, please please remember to make copies and rename your most recent files while working on them.   There is no ‘undo’ button in Piano Librarian!   Making backups like this is like having a ‘undo’ button.

The latest SAT IV firmware and ‘Updater’ software for the SAT IV is free and can be emailed to you.

More detailed instructions and help can be found in the SAT IV Instruction Manual and the Piano Librarian Instruction Manual.    If further help is needed,  call me or Inventronics.
