I recommend using karafun.com for streaming karaoke. The app can run on many devices including TV, PC, tablets, phones. The app is free to try so I'd check to see if it will run on your Samsung. If it doesn't then you'll need to find a device to run Karafun and connect it to the Samsung via HDMI or use Chromecast. Source: over 2 years ago

Try searching YouTube for "Ave Maria Karaoke" and also try visiting karafun.com - simply click on the 'catalog' tab and search for "Ave Maria" and ignore the options to log-in, subscribe or pay $$ unless you are specifically interested in what they offer. Source: almost 3 years ago

I've also used ZynAddSubFX, which is also a very powerful synth, though its interface (at least to me) is a bit of a clusterfuck. You could also try browsing this index of microtonally capable synths on the xenharmonic wiki. Source: about 1 year ago

The code for this can be found here on shadertoy! The audio was made with an Ibanez bass, Guitarix, Hydrogen Drums, ZynaddSubFX and Ardour! Source: over 2 years ago

There are VSTs for Linux. Surge, Vital, and ZynAddSubFx are three prominent examples, as well as OxeFM, Dexed, and plenty I'm forgetting. Surge and Zyn also come LV2 and DSSI, which are native Linux formats. For those who don't know, the VST3 SDK supports Linux, and is released under GPLv3 by Steinberg. Source: almost 3 years ago
