Modular synths/Eurocards

[Niklas Lindberg]

There isn't really any standard (at least not to my knowledge)
so it's up to you to choose your own "standard"...

Since you already have a power supply with a fixed pinout, I'd
suggest you use that (at least for this particular rack).

I also have decided on using the eurocard size (100x160) with
DIN 41612C 32-pin connectors in a similar rack for my modular.
I use pin A2,C2 for +15V, pins A32,C32 for -15V and pins A14,
C14,A16 and C16 for ground.

For your pinout, I'd suggest increasing the number of ground pins
(maybe I will have to do that to) since it is extremely important
to have a steady ground in an analog modular.

As for Gate, Trig, CV or other similar signals in the backplane, it's
the same. If you will be using some common signals that you think
should be reachable by every module then reserve some pins in the
backplane for them...

Go ahead, you're the constructor :->
