[sdiy] control voltage construction help

[Caleb Johnston]

Hi again everyone and thanks for the help in advance.

I have a Roland System 100, which is an analog semi-modular synthesizer.  It 
is only monophonic and I am trying to make another keyboard controller for 
it.  This keyboard would have two outputs.  One for CV and one for the 
trigger/gate.

I am looking for the specs on these outputs and inputs for the Roland System 
100.  Does anyone know where I can get these or just give them to me?

I am guessing 14 V trigger for 10 ms and then 5 V for the gate when on?!  
And 1 V per octave on the CV.  I am unsure about what impedance or 
resistance for the inputs and outputs though.  If anyone has any concrete 
specs for :

trigger/gate out and in
cv out and in

it would make my day.

thanks.
