Back in my youth I did work experience for an engineering firm that supplied the body shells for solid state logic mixing desks. Even had a tour of the SSL factory because they were just up the road in Oxford.

I am saying this because I once had great fun playing around with their matrix desk, and it would be pretty neat to be able to get my hands on one now....

have experience running/engineering control room that had MCI JH#? w/matrix console & 2" 24 MCI machine
Mac 7100 Digidesign ProTools rig was wired into that system for doing edits/mastering
yet that MCI trs "matrix mixer" is not the same as the "matrix mixer" concept people are talking about in this thread

there is definitely a better way to do this but by the time i've waded thru all the forum threads of people arguing about KiCad development and found some script and figured out how to even use it i could have just done it manually. so i will :D

ignore the duplicated normal flags, i have some ideas about normalling something to the inputs, but obviously not all to the same point!

That's a fun stage, let the Sokoban skills flow!

On a more serious note, if your components are numbered in a coherent manner laying that out will be a breeze, since your pots are points that are already defined.

Today I demoted my original matrix mixer to unpowered again :D Something broke ages ago, no longer mixing properly and one of the op amps was heating up alarmingly, but my crammed in stripboard was too messy to fix so I just cut it all out and reconnected it as a passive DC-coupled matrix again. Have it set up to split my main mixer send to various different places and it's working fine for now. Still going to build a new + improved buffered 12v one tho soon

ROUND 2 - FIGHT

Image

started from scratch, i updated kicad and all the links to the footprints in the previous attempt just broke for some reason i cou;dn't be bothered to troubleshoot

had to make a custom footprint for the neutrik nrj6hh jacks i want to use (because they are very compact and I got loads cheap), hope I got it right... was pretty lazy with the silkscreen layer, took long enough getting the pins right so I left well enough alone with just a line to indicate where the front of it is

Going to try and add optional split rail section too so it could be powered from battery/DC if necessary

Looks good, I'll bet the next one will take HALF the time!
