Re: AW: [Doepfer_a100] Matrix module again-Modify current mixers

2004-12-13 by James Husted

Here is an idea. Why not add a multi-pin header to the current mixers 
that would allow their inputs to be chained to each other. This way you 
could chain as many mixers together as you want to make a 4 by x matrix 
mixer (it could even jumper to adjacent rows to make an 8 by x matrix). 
I would guess this could be done now by wiring cables between the input 
jacks of the current models. A better idea - I have always hoped that 
Doepfer would allow access to the normalizing contacts on all the jacks 
used in the modules (at least the ones the can be used) like the old 
E-mu modular. Currantly most of them are shorted to the main input 
pins. This way you could chain the mixers inputs to each other through 
the normalized part of the jacks and by jacking into a mixer in the 
middle of a matrix, it would function normally. All it needs to be is a 
unused pad or donut - no pins or connectors.
