This is the answer from the first name (Dieter Doepfer). I don't know who is
Mr Skirros (maybe you mean Bakis Sirros).

From the technical point of view a matrix mixer is a boring design and only
a lot of mechanics (and consequently causing high costs as the mechanics is
usually the costly part of a module (there are exceptions, e.g. A-111 or the
vocoder).

E.g. a 4x4 matrix mixer is nothing but 16 potentiometers mounted to a front
panel and wired as a matrix. The electronics is nothing but a few low cost
operational amplifiers. If there are sufficient orders we could develop such
a module (but the term "develop" is bit exaggerated in this connection). The
price for a 4x4 matrix mixer would be in the range of about three A-138
mixers. We could add a circuit of the very easy to built matrix mixer on the
DIY page.

Best wishes
