in deffault keyboard preset there is three commands for control crossfader ('home' [left side, 1st player], 'end' [right side, 2nd player] and button '/' in num part of keyboard [center])
but its working in previous version of mv incl. update v 6.411..
p.s.
thats all, I can't give you anymore information, because you seems 'demo version user' and support available only for license holders (registered users)..
"tune in, turn on & drop out
since 2005!"
