[sdiy] Dual soundlab problems

[ben bwise]

Hey,

I know maybe I should just ask Ray Wilson directly , I thought I might
just post this here as its probably quicker and I never post!

I am building a dual soundlab and thought it would be a clever idea
(but now  not so ) if the VCO's could be integrated. Its a bit hard to
put in words so I drew a quick picture in eagle light

You see when you turn up the volume of a vco from the other soundlab
the sounlabs own vco's fade away. I assume this means the other board
is draining the current?

Am I right in thinking all I need to do is put an op-amp buffer
in-between? or am I in the wrong ball park? I obviously don't know
enough about op-amps circuits, ie been looking at the schematic and im
still trying to imagine what is happening
