Encoders on the UC4 and UC44 - and on many (but not all) similar devices can be set to operate in several different modes:
In relative modes, they send delta values +/-1 (or +/- n where n is proportional to how fast you twist the knob). There are at least four different schemes for mapping this +/- delta value into MIDI’s 0~127, though only two are common (two’s compliment, so CC value of 1 is +1, and CC value of 127 is -1 ; or binary offset, where CC value of 63 is -1 and CC value of 65 is +1).
To use encoders in these modes, the controlled device needs to understand them, and have a setting to pick the mapping. Live and Reaper (and most other DAWs I imagine) do. Few hardware devices support them (No idea about the Nord).
In absolute modes, the controller tracks a value in the range of 0 ~ 127 and uses the delta from the encoder to modify that, then sends the new value as the CC value. In essence, they turn the encoder into a pot. But… most such controllers will accept the same CC as MIDI input, and use that to set the internal value. Hence, if the Nord sends the CC value when you tweak it on the Nord (or change patch), then the external controller stays in sync - that is, there is no need for scaled-modes or pick-up modes.
The FaderFox controllers do all of the above, and more: In absolute mode, the internal value is kept per logical encoder - since the encoders can be “banked” - So as you jump between banks, turning the encoder is always a direct delta from the parameter value now being controlled by it.
I use banked encoders on a UC44 extensively with percussion synths in Live. Works great!
Lastly, note that there is quite a difference in encoder feel out there - not just the physical feel, but the acceleration curves and logic applied to the raw encoder signal. Worst I’ve encountered is Arturia KeyLab, which has no acceleration, and poor scaling. Best is the FaderFox encoders, hands down. The acceleration curve is very natural to me.
