Hey there. Finally went out and bought a DGX-670 (spectacular by the way!). It sits beautifully stable on my Z stand, but I want to get the LP1 triple pedal unit (not for soft and sostenudo, but you can assign those other pedals to other useful functions like unison, etc; and I'd like to have half pedaling on the sustain) but would rather not HAVE to buy the DGX670 stand (LP300). I noticed this 3rd party one on Amazon and was wondering if anyone has tried this out on a DGX670, P125 or P515?
