the map is not the territoire

TMINTT is an active Routing and summing Matrix that works with voltages up to the eurorack modular format.

Its principle is quite simple:

Inspired on Meng Qi’s magnetic matrix design, has a patching system that lets you use magnetic pins on a 7 x 11 game board-like grid to route and sum (at unity gain) your signals.

It comes in a usb powered standalone format, allowing you to comfortably interface multiple systems.

This interface will change your approach towards patching, opening a window on feedback territories, focusing into discovery and experimentation, but also just to change quickly your cv signals routing (TMINTT is DC coupled) or your signal FX chain, all this within the map ecosystem.

Embrace a new way of patching, discover places you never seen.



// The borders question:

TMINTT borders can be unstable, the pawns positioning might require a slight adjustment some times, provided that flatness tolerances of the pawns can vary, that’s the nature of the grid.


the map is not the territoire is available direct through our shop! or can be found at signal sounds


the map is not the territoire DIY workshop rev


This will only be available for workshops, wanna organise one? get in touch!

This version presents few differences worth to mention:

 1. it is a DIY version, all the parts are through hole, except for a little smd soldering that is required to fix the headers to the faceplate.

 2. THIS VERSION IS CASE-LESS, faceplate and board are sandwiched together, spacers on the corners are used to give more mechanical stability/resistance.

 3. the magnetic side is made by sticking some ferrous tape on the back on the panel (rather than soldering a metal plate on the back), although if you want to do the second, your welcome to do that, with a few things to keep in mind (will be described in the build guide, PRESS THE BUTTON).

BEWARE: this is an experimental interface, don’t expect to make clean and cutting edge audio mixes on it.

The simple fact that the faceplate and the magnet surface is not flat to an atomic level means that sometimes the magnet requires to be repositioned to ensure contact with the exposed traces. 

The extreme geopolitical borders of the map grid are unstable and not often reliable.


following here some pictures of it:


The Map Is Not The Territoire


Starting with LAKE LEE i went into a deep dive into cartography aesthetics, I’ve been obsessed in the way things were simplified and the various techniques to render 3 dimensional information on a 2 dimensional plane. Which brings me to contour lines, for a moment i had the idea of making a theremin, which antenna would have been formed by copper contour lines taken from a map drawing.

                              Eduard Imhof’s Chomolongma* map, as can be found on the Swiss                                     Atlas, was my go to drawing for making it. After some research though                              i realised theremin circuits require some hard to find parts such as                                 variable inductors (really hard to find!). A research showed                                      alternative circuits with variable capacitors, an easier part to find.                                Although the existence of motion and proximity sensors made me                                        realise how come there weren’t many analog alternatives to these                                   two circuits. So i kinda let this thing on the side, till I get                                     better into coding.         

                                                                   *Mt. Everest


                               But since I really wanted to go forward with the idea of using                                      actual contour lines on a design and wanted to revise LAKE LEE, I                                 went for a new matrix mixer design ( I really like matrixes! )                                   which could be sold to the public.



                               There were few things i wanted to change :






                         I wanted to make it look more like a combination of a game board and a                            map,   and I wanted something grid-like shape, which in a way recalled for                        me both the grid divisions you find on a map AND the game of go grid too (




I found on the internet a beautiful website which

gives you contour lines renderings of EVERY PLACE IN

THE WORLD in .svg format ( what do you want more from

life? ) .

So after spending some time scanning the best places

in the world for contour lines I found out a sweet


This spot will be our play area.




I wasn’t happy with the passive design, so I went for a fully buffered (both ins and outs) matrix design, which is quite simple to implement, as I did on the Instruo lìon matrix design i decided to normalise each outs to the next one from left to right ( with a pattern of inverted-noninverted ) . This means that if you know how to read your map you can have your signal phase inverted! 

In terms of power, I didn't want to have to worry about finding a power supply which i’ll needed to supply with the instrument, so I went for what you can find in almost every home in the civilized world, USB . This thanks to a cincon DC-DC power converter, which takes 5v in and puts out + and -12v ( oh yes i didn’t told you, it works up to modular levels! ) .


I wanted a nice clean black steel enclosure enclosure too,

which has been designed by a dear friend ( Andrea Rossi ),

and which I’ve got made in china

( as almost all the the things I get made ) .

On the works some really nice

looking mexican bocote wood sidecheeks .
