Hi !
Several questions here, I'll try to answer them the best I can.
Erasing presets only works on the bottom row of the matrix!
So: If you want to use the other positions of the preset matrix you have to start a new project in the midi control center with empty presets and send this new project to the MatrixBrute.
It looks like your "Memory Protect" switch is still set to "On". If it's the case, all presets that are tagged as "Factory" can not be overwritten.
Another thing, which is more of a feature not mentioned in the manual is that it is possible to copy sounds from one saved project to another.
True, this is something that could be added to the manual. Will look into this being done. I believe this feature is explained in the tutorial video though :

I seem to remember that an older firmware version allowed you to view which presets contained sequences and which did not just be pressing the patters knob when in preset mode. It seems to have disappeared when I upgraded.. anyone still have this option?
I have ran a fair share of different firmware versions during testing and I do not remember seeing nor knowing about this feature being implemented. I may be wrong though ! Anyway this could be interesting to have, I'll make sure it is listed on our side.
An option that I think should be included in the next version of the Midi control center is "renaming" projects. "device_2" and "device_3" ....it's all rather nondescript and vague. It does not give you a clue as to what presets or sequences a project contains.
It is actually possible to rename a project !
Select the project you want to rename, and then double click on the textbox that displays the name of the project (see picture enclosed), you'll be able to change the name
Hope it helps !
