My understanding of mixers like the A 138 is that they are designed to NOT produce the effect that I want - they are designed to minimise the artefacts of bringing the signals together. I'm specifically looking to create interaction effects. As I said in the initial email about using a mult " it would be non linear and give more rich harmonics - or so I understand. ( Page 175 Electronic Music: Systems, Techniques and Controls, Allen Strange)." It is what Strange suggests - using a mult - but I'm wondering how to make it "safe" for the oscillators.

Then again, a normal mixer that does not amplify (for instance the doepfer a138a/b) is also a unity gain mixer if you turn all the channels you are using to the maximum setting.

The module you want is a unity gain mixer/summer - it is like a mixer without the level controls. I ntellijel designs makes one called the Unity Mixer for US$75 (on Analogue Haven - http://www.analoguehaven.com/intellijeldesigns/unitymixer/ ). It is a dual 3-in 1 out summer that is normalized together so can make a 6-in one out summer. It is also only 2HP wide. Very useful if you have VCOs with only one V/Oct Cv in and you want to drive it with a sequencer and transpose from a keyboard for instance.-James

Hello David
So would buffered mults work in the same way but with no riskNo buffered mults wouldn't work at all. They are the opposite of a mixer
(think them as 7 aux sends of a mixer, with send volume turned fully up).
A mixer is a mixer. Thats it.
A multiple in your planned setup is simply a shortcut between two
outputs and one or several inputs. Using them may work some way, as long
as you are feeding them with the outputs of equal modules. Feeding them
with the outputs of different modules may cause troubles; but as long as
they are built like Doepfer ones (a serial resistor in the output path),
you won't kill them. The troubles may be in the dimension of "one signal
suppresses the other signal in a significant way" or "signal A causes a
frequency damping of signal B". This may be fun or may be an unwanted
effect.
