You need to put a VCA in the signal path if you want the volume to
change.
If you just have the CV output of the envelope controlling the CV
input of the VCO, you will sweep the pitch of the VCO.
If you run the output of the VCO to the signal input of a VCA and
the Envelope output to the control input of the VCA, you will sweep
the volume of the VCA. If the initial gain is set to zero, then the
envelope will sweep the volume from silent to the Sustain level, to
back off when the gate is released.
This is really the most basic synth patch there is. Or perhaps I
misunderstood the question
If you need basic primers on how to make patches on a modular, try
downloading the Arp 2600 manual off the web.
