After (regrettably) purchasing Cubase Pro 10, the only area in which I felt it actually shined above S1 right now is the channel effects that you get automatically on every channel without adding any plugins. I know we have fat channel right now, but that is missing some kind of distortion/saturation, and there is something very fast about opening a channel and just utilizing those basics without pulling up a plugin. Further, the customizability of switching between a few options for EQ, compressor, limiter, and saturation are appreciated, and each of these is visually appealing and at a good level of feature depth for a channel strip.
If a channel strip like this became available for S1 without plugins or inserts I think it would put the mixing experience even further above anything else on the market right now.
