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
