controlling amplitube 3 with fcb1010

[Louie Angulo <louie.angulo@googlemail.com>]

Hi gang,
im trying to control a demo version of amplitube with the fcb1010
so far i can only turn on an fx doing the midi learn and assigining a
control change but i cannot turn it off
ive tired different things but still no success
this is what ive tired so far:
control change 01 value 00-127
ive tried using 2 control changes using the fcbs CC1 sending CC 01
value 0-0 and then CC2 sending 01 value 127-127
however it works when i assign
FCB button 1 control change 01 value 00-00
FCB button 2 control change 01 value 127-127
any ideas?
