They are free running unless the synth deliberately resets the phase of the oscillator on each note-on. Some synths do this to make bass notes punchier. Doesn't matter if it's DCO or VCO. Minitaur has switchable phase reset for example, which is ideal, since you can choose whether you want it or not depending on the sound you're after.

Digital oscillators, depending on how the firmware/software is written, may be allocated as needed, so they would tend to start at the same phase when they are instantiated. This is especially true in softsynths where optimizing CPU usage is important.

A digital VA with a smaller fixed number of voices is more likely to have free running oscillators.
