just a little extract from one of davey daves posts
I will have more detailed specs on the faders (ie:brand) when the X9 is shipped very soon. The sharp crossfader curve is comparable to that of a Vestax 07 ISP. The X9 also has curve adjust on all channel faders, crossfader reverse, and channel fader reverse on all channels. You can also send a sample to the crossfader , not only sample fader start, but you can route a sample to the crossfader so you perform fade ins or "transforms" with the sample and crossfader.
