I recently decided to sample it using my Focusrite Scarlett soundcard. I recorded each drum sound as loud as possible without affecting their peaks and kept the noise floor as low as I could. For recording, I used FL Studio 20 Edison.
The result is what I think is the cleanest sample pack of the Yamaha RX-11 available online. I've made a small demo showcasing its sounds:

These sounds are good for 80s influenced genres of music like synthwave, retrowave and even vaporwave. They have a very distinct mid-80s tone. You can get the pack here:

I hope you'll enjoy the pack!
