I use Jack-rack with my Behringer BCD3000, but in my midi controller effect button is a note and the Jack-rack doesn't aceppted it. So I converting it on midi PC with qmidiroute.
When I pressed effect button, qmidiroute (http://alsamodular.sourceforge.net/) convert this midi note in PC and send to Jack-rack. In Jack-rack that midi PC controls enable button of specified effect. But when I released the effect button the enable button goes off, so for enable button goes on I have to keep pressed effect button.
It works for me.
