Firmware V1.28 Test Version

[XORadmin]

Howdy, here is a question about NRPN in relation to the new mapping tool on 1.28b

I have read this thread: https://xor-electronics.com/forum/showth...p?tid=1021 and many other papers available about NRPN (I never used it)

I'm trying to record an NRPN signal from the Arturia Minilab 3 that controls let's say, the analogue cutoff of the Erica Synths Black Dual VCF. I have entered the following on the mapping tool:

00_MCC_CH1_#6    > CV_PICH_CV1
01_MCC_CH1_#98  > CV_PICH_CV1
02_MCC_CH1_#99  > CV_PICH_CV1

On the keyboard, I have knob 1 configured to NRPN 1:1 (I tried all scales).

The ctrl message goes to the VCF, however there is a scale issue or something that keeps coarse scaling, I can hear it like it has only 128 divisions when moving the encoder, still far down from the 14bits.

Is there anything I'm doing wrong?

Thanks

I did some research and I am not sure if the Arturia products send proper NPRN messages which use the 14 bit range for values at all. All I can see is that they send either coarse or fine and not both at the same time. (Like typically 3 packets instead of four which is theoretically OK following the Midi specs. But the specs are very inconsistent here and totally allow incompatibility between different gear) 
So you could send only one of these 2 parts per controller while you need both parts to create a 14 bit value. And each part is 7 bit = 128 divisions. What you end up with are a high amount of possible controllers bit each with only 128 steps. Using NRPN with these controllers would be a step back compared to just send CC.
