I agree with Koshdukai that the matrix design with its 3 different uses and the 4 assignable destinations is fantastic.  Finally, a real hardware analog modular where you can work on a patch, save it, put it away, work on something else, then go back to the first patch and work on it some more.  That is a brilliant design.
I have a request/suggestion/question.  There will be a computer-based patch librarian, right?  Could that software be used to make all 16 modulation matrix destinations fully assignable if the user wants to do that?  I realize not everyone will want this, but for me a large part of the appeal of a modular design is having as much flexibility as possible.  
I also realize that if I defined all 16 destinations I would probably have to print out the mod destinations on a narrow piece of paper and put it across the top of the mod matrix.  Or write them on a piece of masking tape.  I do not expect you to add a screen to capture that (maybe in a future deluxe model?)

I understand and Greatly admire the strong choices that have been made with the Matrixbrute to have No Menus, no menu diving, one function per knob, that's beautiful, I love it.  That's why I am wondering if the patch librarian on the computer could allow this free assignment of all 16 modulation destinations for users who want it.
Just a humble request/suggestion from someone who owns the Modular V vst, a keylab, the analog lab, and a Spark.  You guys put so much careful thought and innovation into your products.  I am really excited about the Matrixbrute.  It really looks like an amazing step forward.  Thank you.
