Depends on who writes the code.  I could do this with an FPGA board that has more than one DAC
output channel.  One could make any sort of hybrid one wants.  Usually a digital synth's ADSR
signal is just used within the synth itself, but it could be output to a DAC channel or to a DAC
channel and used internally.  This also goes for anything else, like LFOs or ARs.  An FPGA board
with an ADC could also receive CV information from an analog and use that to modulate digital stuff
or it could modify the signal and then send it back out through a DAC.  I think that some people
here may be doing these kinds of things.
