EUB, the game I've spent the last 4 years working on, is finally nearing completion. So I actually feel confident for the first time in years that I'll be able to help with music if you like what I have. However, I won't be able to contribute significantly until after EUB finally launches, which will most likely happen in August, September at the absolute latest. I don't make strictly touhou-style music (I don't have a real SD-90) but I use similar instruments fairly often.
If you need examples, PM me and I'll send you some of my best work.
