Which module has PWM Depth? I don't see it on any of mine.

Actually, quite the opposite. An oscillator never stops producing a
signal. Typically, you feed an oscillator (or other audio signal)
into a VCA's audio input and feed an envelope generator into the
VCA's control voltage input to change the amplitude of the audio
signal. For infinite sustain, add a DC bias to the VCA's control
voltage input. To get a long slow release time, set the envelope
generator's RELEASE time to maximum.
