Sorry – I have no idea what you mean by SNDCTRL, or where Capture MIDI fits in. It's probably that I cannot help you.
On looking at this preset, it seems pretty clear that it cannot be effectively remote controlled. Any attempt to select one of the parameters for remote control gives "cannot remote this object." This will apply to all of the Grafic type EQs.
You could try one of the regular multiband EQs, such as 1210, Eight Band EQ.
