Hi guys,

It's been a long time since I've been onto these pages and this is my first time ever post in the DIY section, to present my first SDIY project.

It's a non-buffered modulation matrix based on a Ghielmetti 36x36 and it is to be interfaced with my Eurorack modular.
At the inputs of the matrix, there are 18 passive attenuators (9 Log for audio and 9 Lin for CV ), same thing for the outputs of the matrix.
All attenuators are freely patchable, meaning I can choose to attenuate a signal or not before it enters the matrix, same thing for signals coming out of the matrix.
I've assigned some default inputs and outputs to the matrix rows and columns but this is in no way fixed. This system offers maximum patching flexibility ( on the contrary of module outputs and inputs being hardwired to the matrix, that would imply a fixed configuration)

Of course, any comments, questions, suggestions are welcome !

Let us know how this changes your approach to patching.

It's a beast!!! Very nice craftsmanship, beautiful panels! This instantly turned the FSU factor to 11,000.

vids please! !!

Well, thanks Steve !

I only have the merit of designing and putting the thing together, the panels were made at Schaeffer's, in Germany.

Before putting it on tape, I'll have to tame the beast :mrgreen:

The question remains: How to approach patching this thing? I'd probably spend one night connecting things to the inputs and outputs, imagining the possibilities, and then the next night get busy with the pins, tweaking the attenuators to suit. Fine tuning is where great patches reside, and this thing will take you there for sure! I hope the patch matrix is not so noisy or prone to crosstalk... ?

Labelling the patchbay with the EMS standard routings is an interesting design choice. Sort of an instant Synthi type of thing. And a nod to the classic synths -nice.

have fun!

It is indeed a different approach to classic patching. I think it will push me to first think through the patch I wanna make and make a selection of signals I wanna work with, then concentrate on the balances and the routings inside the matrix.
The first tests I made proved satisfying in regards to noise and crosstalk.
If I wanted a noise free and crosstalk free matrix, I better bought a couple of Hinton Switchmix (or have a custom made one...) but I think a bit of noise and crosstalk is part of the charm of this kind of system. The interesting character and charisma of EMS instruments (that use unbuffered matrix systems) resides partly in the sometimes unexpected results induced by voltage fluctuations and inaccuracies.
Still, I have to do some extensive testing, in situation, with complex patches. If necessary, I could then install matrix buffering on some rows, as suggested by Graham Hinton on his pages dedicated to EMS.

The labelling is not quite a reproduction of that found on EMS instruments, but I thought it made sense to get some inspiration from the venerable ones and suit this to the available modules within my system.

I surely will have fun, but it will take time for me to get used to it and to be able to work quickly and efficiently.

Wow, that would totally mess up my patching. I'm pretty sure I couldn't keep up with all those pins. But very nice work man!

Finally found some time to make some recordings with the help of my patch matrix presented here:
