Nah I did think about it, but the first error was definitely a broken crossfader, but this now sounds more like software vs. hardware mismatch.
If you have a controller hardware that supports Crossfade curve adjust (like the TM) then you should never touch the Software crossfader adjust and leave that to linear. The software thing is only for cheap basic controllers that have no crossfader adjust of their own.
The crossfader adjust is never MIDI on any controller.
