Yes, the BCR encoders are endless, but are currently setup to send normal controllers.
They can be programmed for other modes too, and i tried a mode called "inc/dec", but with this i got no midi input at all, so i stayed with "absolute". But perhaps i did something wrong, i´ll have to check again.
So you mean such a mode would be generally be better? does it work for all other scenarios too (PC, ACT,...)?
If there is an endless encoder, it is better to use it as endless encoder! Everything else is "compatibility", implementer in the BCR firmware. It can be simpler to dial with that at the beginning, but you get such "troubles" as with level/monitor.
AZ Controller is able to process native signals, for all operations. You just has to set "Value" mode to "Endless" (from "Direct") and adjust sensitivity to your taste. You can also define "Shift+Encoder" more sensitive (Fine) then "normal" (coarse).
Then i´ll have to find the correct mode for the BCR. Reprogramming and transferring the preset is not done so fast, so i can not just quickly try all modes through. Could you guess from the screenshot?
My guess is that any from first 3 "Relative" will work for you (other "Relative" are also supported, inclusive "Inc/Dec", but you do not want them. The explanation for that is going to be a bit long, but if you are interested let me know).
It is hard to guess what is what, so it is better to try all 3 and find which one produce the following result in the "Last MIDI event":
* slow turning right produce value 128, fast turning produce 128/256/384/... depending on speed. It can be that in one mode it produce 128 or 0 independent from the speed (my guess in "sign in MS bit"). It can be that there is no such mode, "second best" is when it produce 128 independent from the speed
* slow turning left produce value 16256, fast turning some another "big" values.
In can be that the result is "reversed", so turning left produce "128". Also not a problem ("Alternative endless encoders" in the Options tab).
