Hi Paul. thanks for the answer. The following is not meant as "told you so!". But I also want to show, that I care about this subject and made my homework. And sometimes a well meaning reply is also wrong: That Aeolus and setBfree are sample-less software synthesizers was not only hinted at through " Guest appearances by Aeolus and setBFree :) " but it also mentioned three times on the website itself. Once under "All software synthesizers" and then in each individual description. The samples from pianobook.co.uk all do not fulfill my requirements. See also their terms and conditions: https://www.pianobook.co.uk/terms-conditions/ Quote: " You may not sell sample(s), or give away any sample(s) for use by any other person(s)." And to anticipate one possible reply: My list is not a matter of what is fair and moral and possibly enough to make music. It has a 100% clear, law to the letter, no exceptions approach. I also wrote: "The strict constraints mean that this list will never be very large. Creating sampled instruments is a time-consuming and expensive task and is usually undertaken with the intention of making money from the result, thus not distributing the instrument as free and open source. This is by no means condemnable, but in this case it is simply not our topic. " And finally, from your .sf2 image I can tell at a first glance several well-known illegal rips, instances where the authors falsely claimed "public domain" and cases where the license simply do not meet my requirements, the requirements I prominently put in their own chapter. For example Florestan is well know copyright infringement, SC55 is already clear that these are just Roland samples, G-Town is not as free as people like to think, they are probably worth an entry on my "Other list" (that is linked on the page). Some of the .sf2 are synthesizer sounds, which I clearly declared "out of scope", even if they were CC0 sf2. And maybe they are just bad sounds. As I wrote: "They either have to be of decent quality, or at least be the only ones of their kind." For example balafon1.sf2, which I even created an .sfz version from in 2012. However, I would not recommend that to anyone because I dislike the sound. So, it is possible that a few of these .sf2 are indeed good fits for my list. And in this case I welcome any suggestion, as written on the page. However, I require a source that I can review. With the risk to sound grumpy as well: This time my efforts were already ahead. The "full picture" is sadly not as full as it should be. Not many people have the time, money and skills to produce samples, and that shows. People are desperate and want every sample-lib to be free and good. But most of the time they aren't, but yet another EMU Proteus rip, or something like this. I hope this example of the research-and-elimination process shows why I think I am the right person to create that list.
