Individual drum sensitivity settings are based on watching the velocity bars and trying to find a balance where only the hardest hits peak at 127 velocity. My hihat cc max is set to 127 instead of 90 in the TD12. I also have to load my own saved e-drum preset (with corrected note mapping) and additionally manually select the more closed hi-hat setting each time as the hihat always defaults to not fully closed. The snare goes from very quiet to maximum thwack very abruptly, the crash has no quiet dynamics etc etc (maybe positional mapping needs to be done with an x-drum for a smooth transition?) When I play SD2 I find the dynamics aren't nearly as good.

What I found is that playing the TD12 internal sounds I get a pretty good feel and range of dynamics, though I find the sounds unconvincing (which is why I bought SD2 - the quality and range of sounds is fantastic) Latency is about 9ms which means I usually need to put a negative track delay so things line up. I'm using SD2 as a plugin within Ableton and all of that is working smoothly. The SD2 manual isn't very detailed and the included 'e-drum preset' is only a basic starting point (rack tom rims and hihat need to be remapped for example). Hi, like many others probably experienced, I've been having a bit of a struggle to get the best playability and dynamics out of Superior Drummer 2 with a TD12.
