Hi,
So lets say I have a theremin module A178 and I want the entire range
of control of the theremin to only affect one octave of pitch.

I imagine I can do this with a A129-3 via attenuation and offset, is
that correct If the output of the theremin ranges over 5 volts
normally (is this true ) then if I attenuate it it will range over only
1 volt.... I hope. Then I can offset the output so that the volt in
question will correspond to the octave of my choice.

Is this all accurate
Is this the best way to do this

I think maybe it is also possible with the A138c using the offset
function of input one.

Please let me know,
thanks,
Rafael
