For those familiar with "Sky Music Nightly"

Hello hello!- apologies for the strange formatting, this is my first time posting to this subreddit...

Anyhow, I'm a complete newbie when it comes to Sky's music and instruments- but I've been wanting to learn a song or two. During my research, I stumbled upon a site called >Sky Music Nightly<-- which has been a great help thus far, though I've one issue with it......

It's missing practically half of Sky's instruments! ;;

I was specifically hoping to test out the Triumph Violin- but it's nowhere to be found in the site's options--- am I just missing it?- or does it really not include certain instruments?
