Inquiry on Razer keypad multi-button press w/shift state?

I've had an aging Belkin Nostromo N52 for quite some time now. I purchased Razer's initial Nostromo release way back in the day as a replacement and noticed the software was quite limited and there were issues with the controller not being able to manage multi-button key presses with shift state being utilized. Something the old belkin units have no issue. I was forced to return the razer nostromo unit.

I've researched reviews of the later Razer keypad products and software appears to have caught up as one can implement mouse clicks and the like in macros now. However others are still reporting what appears to be a similar issue with shift state and multi-button presses.

I've been utilizing the belkin nostromo n52 keys (8,12,13,14) for as WASD movement, the 11 key as the hold to shift state, thumb pad for jump, shift state thumb pad for run, and the d-pad for macro abilities along with shift state the d-pad for doubling number of macro'd abilities.

From what I recall many years ago the razer unit had issues with the d-pad being shift stated while still being able to utilize the keypad as WASD. Does anyone know if the latest Razer Tartarus is able to be utilized in this fashion?
