No its not basic, it need lots of technical fiddling to do in renoise. Also there are always different ways, each having different advantages and disadvantages.
I attack for you an example of a velocity sensitive bassdrum I just made inspired by your post. I did the sensitivity by using velocity trackers in the modulations, but as I said there are other possible techniques to achieve similar functionality.
Look at the instrument modulation, the vol will react to velocity, but will scale only from 50-100%, not the full range, so low velocity will have half amplitude, full velocity full range. But also look at the pitch, as this was your question. I used the vel tracker there to scale a pitch slide, so higher velocity notes are not only louder, but also much more aggressiv/snappier, shorter also though and less bassy. Maybe you get the idea of how to use vel trackers in modulation. It is not very straightforward. The tracker will output a value from zero to one depending on the velocity the instrument was triggered with. You need to view the operators as math operations in a formula, calculating strictly from the left to the right, and you can be creative with stacking operations to shape a response that is interesting for you. I think there is a limit of like 12 or so operator devices in each chain.
