I’m sitting in preparation for a show and still miss the MATRIX CLEAR button 
what you mean?
Reset Button and Matrix Mix Button?
a button that deletes all matrix points in the I/O, i. e. sets them to zero.
but only for the selected matrix.
I hope this is better understood?
still don’t know what you mean
Okay, then I guess I didn’t pick the right words.
well, it is very easy to delete a 1:1 matrix patch in the IO Patch. you just move your finger along the matrix points (I have configured it so that I also have to press a patch button).
but if you have configured a more complex patch in the matrix (for whatever reason) then you have to touch every single point to delete the patchpoints.
so I think it would be good if there was the possibility to program a button that can delete all patches in the displayed matrix at once.
above the matrix would be enough space for such a button.
I hope that was understandable now
Yes, get it now…
indeed this would be an improvement…
there are more places that could use a clear button
Mute Group Assign
DCA
Talkback assign
yesss 
I would like to put my request from 2017 in the spotlight again.
Meanwhile there are a lot more users here, maybe one or the other of them would like to have this feature and would like to join here.
I still miss it
I am totally with you!
There are no more friends for this feature.
So this will end up far behind on the priority list
three is a group already
