I bought a Trackir 4 some weeks ago and I find quite difficult to get used to it, as it was a pain to keep it fixed on the neutral point, even playing with the speed and smoothness sliders and loading some of the presets.Yesterday a gave it a second chance and found out the key was editing response curves to your personal taste: might sound obvious, but I didn't try on my first attempts.It came with a Trackclip Pro (came as a bundle) but I do prefer using the trackclip with a cap!
