Bought the Nektar NX-P to use for dynamics in orchestration. I've seen comments suggesting that this pedal is identical to the M-Audio EX-P, but I disagree, because the NX-P has a longer travel range, which is exactly why I prefer it.
For its price range, it offers a good quality-to-price ratio. It features a medium travel range, a sensitivity adjustment pot, and a polarity switch. While it’s still not perfect or exactly what I’d expect ideally, I’ve tried several different pedals, some much more expensive, and this one seemed the most suited to my needs.
