cavernut, the MicroTrack doesn't have the ability to take an incoming digital signal and resample it to a higher rate, if that's what you mean.
This is completely aside from the question of why you might want to do it; there would be no improvement in specifications or performance if it were possible, since the recorder would merely be recording the identical information while consuming twice as much disk space per unit time. But anyway the recorder just doesn't have that ability.
