I wish this soundfont could be compatible with general midi

This keyboard has few presets, some are just variations of it, and using the same sample as a base but with different ADSR settings, or even the base sample is used 2 times and the second sample is added some detune to obtain a chorus effect. The other thing that is done is to use samples combined with others. Therefore, this keyboard has very few presets, insufficient for General MIDI compatibility, unless a creative soul makes other presets using the same samples but it would still be the same thing.

I was thinking about making a soundfont of the SW10, but two issues arise:
First, the SBPCI sound card installed on my Windows 98 VM outputs at 22KHZ, which removes brightness from the sound. This is especially evident on things like drums. Even though the original samples aren't super high quality, they would benefit from using a higher sampling rate, but I don't think I can attain that, unless there are other drivers I should try or some virtual hardware settings I should be adjusting.
Second, even if I get past that problem, the SW10 uses a lot of layered sounds which I could not find separate layers for. Especially in a lot of synth pads, there are sometimes two sounds playing at once which I can't find in a separated state, so it would be impossible to sample them accurately. I'd have to use a sort of brute force sampling approach where I make long loops of single notes rendered by the synthesizer. I'd like to avoid this if possible.
I do have other synths in mind though, not from Casio unfortunately since I haven't had much Casio experience. Roland and Yamaha were the main companies I was familiar with growing up, with Korg and especially Casio being less on my radar, though I am still interested in their sounds.
I recently purchased a Korg X5DR module from EBay and I really like it. It's an old entry-level GM sound module from 1995, though it does have interchangeable banks of non-GM sounds too which are really what make it interesting. It still uses a lot of their high-end technologies which existed at the time, so it still has a lot of awesome vintage sounds and samples. You can create your own patches too and access the individual waveforms. This is pretty rare for a synth in that price range, but it is something that will make sampling easier, because I can start from an initial patch and scroll through the waveforms and record clean separated samples, without envelopes or effects!
I was also thinking of sampling the Roland SC55. Sadly I don't have the module, but I do have the Sound Canvas VA VST which is an accurate emulation of the SC8820, and it contains SC55 sounds. Some of its parameters and sounds aren't accurate to the real SC55, but most of them are close enough, and I plan to fix some of those inaccuracies by referencing midis recorded from a real SC55 from this site. I also haven't seen too much layering going on, and with some work I can probably minimize the filters and envelopes and the like, so I should be able to get mostly clean samples.
For the record, I've started on sampling these synths but haven't gotten very far. It's something I plan to do more, but when that actually will happen is hard to say lol.

The SW10 is a software synth which installs as a Win 9x driver, so you'll need Windows 95 or 98 to use it, I think ME will work too. The installer is in Japanese but it is not hard to install. A VM will work, which I imagine is what most people will be using, but you'll get a lot of lag, and with the SBPCI drivers I have, you'll be restricted to a 22K sampling rate. I'm not sure if there are other sound drivers that will work better, but those are the only ones I've tried, in fact they came with the VM which I got from Jake Gross's web site.

The download link for the SW10 that I originally used seems to be down, but I was able to get it before it died, and kept the setup file around. If you're interested I will give you a link to it.

Also a benefit of using the SBPCI drivers is that you get an emulated SBPCI synth which has some pretty nice samples in it. In fact the different wave sets (2mb, 4mb and 8mb) are still available on Sound Blaster's web site but I don't remember where you have to go at the moment. These wave sets are not .sf2 files, but are rather .ecw files. There's an exerimental utility to convert .ecw to .sf2 but I haven't tried it. The only .ecw files I am aware of are the wave sets I mentioned; it didn't become popular and was soon replaced by Creative's sound font standard.

Wow, awesome obscure piece of software! I don't have a Win 9x, so I can't install it. I do not think my PC supports a VMuare and those things.

So I am seeing this post and I downloaded the Songs to check them out. But I have a couple of questions. One is "How can I download this font because I tried hitting the link and I didn't see a download button or something. I just saw the link to get the songs." And the other is: "How can I use the different sound fonts? How do I put them to use?"
