Oh no, turns out the FM synth I got off Aliexpress has a bunch of different firmwares out there that all look really good. I just bought one because it was a capable synth that was surprisingly cheap, I saw it as a potential beatmaker but not much more than an elaborate toy.

You can turn this thing into a groovebox, play Doom on it, make it a dungeonsynth machine. I thought they were cheap but the real cost is in buying multiple to have each firmware at hand at all times. I can't believe what a sucker I've been
