Sorry forum, I tried attaching images to my original post, but the file sizes were too large, then I tried with pdf's but they were unsupported. I think I should be able to attach the photos now as I reduced the image sizes.

Here's a link to my original post

I thought it might help if I posted back with some photos of screenshots that illustrate what happened when I tried auditioning a Voice Library with Samples to my USER SDRAM and then Loaded my ALL DATA file to restore my original settings. I am hoping that you can help me understand some things that do not make sense to me as I went through this process.

I began this exercise by taking note of what was in my FL1 before and after the process of Loading the library to USER SDRAM. Please see photos "FL1-1" and "FL1-2". These show the Waveforms that were in FL1 before I began Loading anything new to my XF. I had 16 Waveforms listed, with the first five belonging to Chick's Mark V and the remaining eleven belonging to a Piano Library.

Next, I thought it would be good to go into INTEGRATED SAMPLING to document what was there. You will see in photo "Int Samp-1" that nothing is listed there. Again this is what I saw before Loading anything new.

I then Loaded the new Voice Library (with 126MB of Samples to my USER SDRAM. I loaded this as an "All" file as I figured this would be a 'worst-case scenario' in the sense that it would overwrite everything in my XF, all the while knowing that I could always restore my ALL DATA file with all my original settings. I should point out that I had Saved two ALL DATA files, one "With sample" and one "Without sample", in case I lost my Samples and needed to get them back.

After Loading the new Voice Library, I took a look again in INTEGRATED SAMPLING and saw the new Waveforms listed there. Please see photo "Int Samp-2" and you will see that I have new Waveforms listed. This is what I expected based on what you wrote in your last post. The Voices all played and I was able to audition the entire Library. OK, I thought this all made sense.

Then I decided to Load my own ALL DATA file Without sample, as I know by now that all Samples in my FL1 will remain there until I either delete them or re-format the Flash module. The Load setting was: FL1>Without sample. I know from what you wrote that I can take "Without sample" to mean with waveform. You also wrote the following:

As long as you are loading from a personal backup file (one that contains your instrument's personal Waveform List) the XF will "know" NOT to duplicate Waveform data. So when loading from you own files the XF will NOT duplicate Waveforms.

All of my original data was restored as it originally was before I began this exercise, with one exception: All the Waveforms I originally had in flash were in fact duplicated. Instead of 16 Waveforms, I now had 32 Waveforms listed in FL1. See photo "FL1-3" and you will see that the duplicate Waveforms start at 17 and continue through to number 32. I didn't take a photo of the remaining Waveforms, but I hope you get the idea. Well, I thought this did not make sense based on your explanation. As a test, I deleted the duplicate Waveforms, and the same thing happened as the last time I tried that: None of the Chicks' Voices nor the Piano Voices dependent on what was in FL1 would play. Silence!

Next, I Loaded my ALL DATA file Without sample again, but this time with the following setting: FL1>none. This time, everything was restored to my original settings, with all Voices, Performances, Masters, Patterns, etc. all playing properly. No duplicate Waveforms were present in FL1.

I am glad I was able to restore my ALL DATA file, but what happened does not make sense to me. Do you know what might have happened here?

Also, I thought it was interesting that, although the Waveforms for Chick's Mark V have the suffix, .wav after the Waveform name, the Waveforms for the Piano Library do not have the suffix. Any idea why that might be?

I will continue to work through this as I think little by little it is starting to make sense, but what I described above does not. I would appreciate if you could share your thoughts on this.

Thanks in advance,
Brian
