I've got the Expansion manager running great using WINE so it was time to work out how to merge more than one pack together, my previous keyboard (PSR-S650) could have one Expansion pack installed at any time, the S970 has 512Mb of memory so can have more packs installed at once (if they are merged into one).
I also wanted to see if I could bring in some of the style tracks from my old S650 packs.
Importing packs is easy enough, you just click on the +, locate your Pack Project File .ppf and it's imported.
I also found I could locate my old S650 packs which are .YEP format.
Some instruments could not be imported as they were using a different format but that was OK.
The question now is how to export these out in a file format that I can load into the S970.
The sparse Expansion Manager user guide mentions loading your instrument info file.
I found this is located in the System / Owner screen.
Just OK the question and save to USB , this will save a file with the correct .n27 suffix file (your instrument info file)
Launch the Expansion Manager, on the left select the + next to install Target , then select the "import instrument info".
Locate your .n27 file
This will be imported into the Expansion Manager.
The Install target will show your instrument name, after a few seconds this will colour in a purple colour.
You now have the instrument programmed into the Expansion Manager.
To import expansion packs remember to select MY PACKS at the top left, this gives you the option to click + and import etc.
You can save files and custom pack settings in MY PACKS but can't use them in the instrument.
To do this click the PSR-S970 on the left, you now have the option to select multiple packs (Green tick), or deselect them. You can also highlight files within the packs and exclude/include.
You now select "Save as Pack Install File"
When you save the pack you need to add the ".ppi" on the end, otherwise you can't load it in the keyboard so just check it's there before you transfer the file to the USB pen drive.
Insert the drive, Press the Function button, select the pack, in this case I've added several of my S650 packs so there are 14 packs merged into one.
Once installed the keyboard will restart.
Voices and Styles are there - I wouldn't expect everything to work, after all I've imported some files from an older keyboard but they are there, it's just a case of keeping note if anything does not work, then you can customize the pack a little more in the Expansion Manager and load it on the keyboard which will remove the items which you don't like or don't work.
