Yes, it is possible to specify a depth modulation in a custom stimulus: however the left and right components have to be created separately using the 'L=' and 'R=' prefixes for their x coordinates, and the depth modulation of a carrier stimulus should be created by specifying a disparity envelop and calling the dshiftp(carrier,disparity) function (the left and right versions having then disparity envelops with opposite sign).
We attached an example that we will add as a demo in the next version of Psykinematix.
Note that the 'D=' format can only be used to specify a global disparity and only used in the x coordinate field!
