Though I'm currently enjoying the FM9 Turbo for bass exclusively, bass support has always been a sticking point for many of us. It seems inconsistent of Fractal to purport their products to be great for bass - and they are - yet not include a small number of stock bass presets. Thus I've come to understand that this is just the way it is, and will likely always be with Fractal sort of walking a fine line, not wanting to ignore bassists, but not going much out of their way to actively court the bass community.
I've accepted this and just enjoy the FM9 as is, with no further expectations things will change, but happily surprised if they do.
