I2C output value freeze on V03.01

[Simontl]

Hi

I'm experiencing an I2C output value freeze on V03.01:

Hardware:
Sweet Sixteen mkii -> Nerdseq -> ER-301+Disting NT

Issue:
When trying to send a modified I2C output to ER-301 through mapping setup.

After a short while all output I2C freezes.

I can confirm in Disting NT, that it stops receiving I2C.

Nerdseq is still showing an output is sent inside mapping setup.

I found it with a more elaborate calculation in mapping setup, but it is also happening with the following setup:



Midi/I2C setup:
I2C A Mode: 16N->NS -16
I2C A In Address: Hex: 31 Dec: 49
I2C B Mode: Out Merge
I2C B In Address: Hex: 31 Dec: 49

Mapping setup:
I2C SCCV #15 > I2C B CV #25

It seems with your setting you cause an overflow. The Basic setup sends all data back to back to port B already. And in the mapping you additionally send CV15 to output port 25. This will cause double the data when you move fader 15. It is possible that the incoming fader data is filling much of the data line already. Even if it would only fill 50% that would mean an output of 100% which surely can cause issues as there is not even a save space. 

I suggest to pass only the needed faders to the disting with the port in out only mode or you do the merge but no other extra mapping. It could be just too much.

Thanks a lot. Makes total sense.
