The sad truth is that it is very unlikely that they will ever reach the quality of Coakley's ones. So why I'm strugling to make those soundfonts? Because nobody else does! This is a known problem that has been discussed several times in the freepats lists. There are very few people willing to give their time to create free soundfonts (Marcos Guglielmetti, main developer of the Musix GNU/Linux distribution, is one of the very few exceptions). Few people realise that most "free" soundfonts out there contain unlicensed samples. It is easy to recognize copyrighted samples in those soundfonts from manufacturers like Emu, Korg, Roland, Yamaha... There are lots of sites in the Internet with "royalty free", or "public domain" samples, but actually those samples are ripped from some unknown (most likely copyrighted) source. Just exactly like free software, free samples need to be unambiguously placed under a free license by *its author*. And of course the author *must* be identified. Thinking that they are free because the author is unkown is just too much optimistic. They must be recorded from original, analog instruments, or synthesized from scratch by the author. The samples contained in hardware synths/keyboards are subject to copyright in the same way that proprietary soundfonts, so they can't be used on a free soundfont. There are very, very few free samples out there. Note that the license used in sites such as freesound.org is not free in the freedom definition used by the FSF, since it does forbid some kinds of commercial usage. So my first and most important goal is to create a collection of free samples for several instruments. Next, it is required to create soundfonts from those samples. With my "demo" soundfonts I just hope to get the attention of some people. We manage to get high quality, free software operating systems, thanks to the collaboration of many people, so I still hope that people start to join to the freepats project, stop using their pirated, "semi-free" or proprietary soundfonts and begin to think about actually working on creating really free, high quality soundfonts. I must say that I'm not interested in dedicating such amount of time required to reach the quality of Coakley's soundfonts. I will fix most things, and try to improve the balance, but I'm currently not interested in building a small soundfont that sounds as good as the big one, is not my priority. Instead, is very likely that the next version will have two additional layers (and thus will be bigger, sorry). This is a quote from the article: "[...] it takes LESS time and LESS work to develop a 3 gigabyte piano than it does a beautiful thirty two megabyte piano[...]" It's true. If only two layers are used, a lot of work is needed to create fake layers in the middle. It is needed to carefully filter higher harmonics and blend the result. It could easily take months of work. But I don't agree with some of the statments given in the article. It is certainly possible to create fake intermediate layers that sound as good as the real ones, but claiming that they can sound *better* than the real notes recorded from the piano is no more than a beatiful way to advertise his soundfonts. As Coakley says, it is just easier and faster to do the same with more samples, and that's the real reason. If the samples are well balanced in both big and small soundfonts, the bigger soundfont will sound at least as good as the smallest one, and probably better (it will use much more RAM, though). Producing a good soundfont with less layers and half the size would be desirable, but unfortunatelly I'm unable to do that myself alone. If someone is willing to donate his time to work in this area, please let me know, it would be great.
