So, I've heard pros and cons for both.
While RYM2612 is more full-featured and offers a better GUI (and better customer service), the price point is higher (€49) than FMDrive (€20).
So, which one is really worth it?
Also, the other thing:
I've been using Plogue's chipsounds plugin for emulation of SN76489. It's very good, especially with pitch bending. Is it the best thing for that, though?
