Re: -- encoders type ? --

What I know about encoder resolutions is represented in section 17.3 of "BC MIDI Implementation.pdf".
In any case the default resolution is 96/turn (24 also seems a "basic" value), but I'm not sure what to read into that.
To be absolutely sure how this relates to the hardware, I'd have to analyze the firmware, which seems a bit over the top...
