Yes; that more or less makes 2x upsampling essential.

Isn't there always a discontinuity here anyway? When it changes from
attack to decay the rate of gain change switches suddenly from
negative to positive. A bandwidth limit on the control signal
should take care of that, as long as the cutoff is steep enough.
