I know this isn't 3d stuff, but one of my other hobbies.

Thank you! Still working on the final draft.

A variety of them. They are all digital instruments. There's the lute, flutes, harmonium, drum, some other stringed instruments.

I have no idea what it is because it's built into a free DAW I use that has thousands of built in VST instruments. It's very fiddly to get results, and I usually record individual stems and then tweak them in something like Audacity or even Melodyne. For any instruments or percussion I can't find in the instrument pool, I do all that outside of the DAW and just splice them in on a new track in another program. Most of the other audio programs stopped working for some weird reason. That's one thing I hate about modern DAWs, because just 15 years ago you could pretty much take a regular PC and install Acid Pro without any fuss or special external devices. It just worked. I could record an arpeggio from a keyboard, and then import it to Acid Pro no problem. Playback worked, and everything else. Now it's like pulling teeth from a chicken to get any of them working as is. Now I have to hunt down all kinds of user patches and hacks to get anything working and that means any A/V codec updates might break the DAW. So it takes a lot of effort to get something out of it. I even have a second PC set up for just DAWs but it stopped cooperating with DAWs all together. It's been rough.

The crazy part is I built my second PC intending to make it into a Hackentosh, with a sound card that was compatible with iOS, but it was too intimidating to get iOS installed, so I reverted to Windows/Linux Dual Boot. And now it refuses to cooperate with DAWs. I can't fit the sound card into my main PC build because of limited slots/room inside the case which is pretty large, but the board doesn't have enough PCI slots on the lower end, even though it has more than the standard board. I have 64 GB of memory, and it runs most if not all AAA games easily. It just doesn't seem to play nice with too many things plugged in to the board. And to top it off one of my UPS units decided to have a dead battery so I have to wait to buy a replacement battery before I can mess with the 2nd PC again. I was told I need to buy an external sound card that plugs in by USB instead, but they often don't tell you if the sound card comes with the necessary software to guarantee DAW compatibility. I can't afford to shell out money for an unknown that huge. That's what I mean by user patches and hacks that bypass the need for an internal or external sound card. I tried to find one that works but they are elusive, or don't work anymore. They need to go back to the compatibility with onboard sound cards instead of the duct tape and bailing wire approach, and a free DAW that does that would be so popular these days. As it is the one I use runs in it's own proprietary browser which means it doesn't need a purpose built sound card to function, play back or record. It just works, but it's a pain to work with inside the program itself. Like the layout, and how the note editing works. Some of it is really counterintuitive, so getting any music out of it is a celebration on it's own.
