I didn't know dirty FM was a niche I was looking for.
Brzoza has an emphasis on gritty, dirty sounds rather than 80's funky basses or soap opera keys. It's easy to run into delicious mush and you can make lots of great faux-distorted leads and reeces. It's not the type of FM synth to chase the clear, bright qualities of a synth like Dexed, or a passing DX7 emulation; it's more for metallic grime. I love it for horrific dissonance.
