Oooh ... I hadn't seen that poll. (Clearly, I need to dig into the forums more.) I'll likely chime in there, too, but to answer your question:
- Trance and Techno, because I want to make them
- Chillout and Ambient, same reason
- Drum and Bass, because I just don't understand it. (Honestly, I'd at least watch any genre, just to get that understanding.)
I've also poked around in the Synthwave tech tips from a few weeks ago ... I just haven't managed to close the circle and actually make something, yet.
I'd also love a "here are some different sub-genres of house/trance/techno/whatever, and here's what makes them different" style of tutorial. But, I have to think that the religious wars that would come out of that ("How dare you?!? Hyper-mega-trance-house-step is at 128 BPM. 129 is Hyper-ultra-trance-house-step!") might not be worth the effort.
