Foot keyboard x50

Hello, i am brasilian and love dreamfoot.

I am using the keyboard foot to change the chord, it happens that when i change the chord, i need to hold the foot, and then release to change to another chord.

When he only wanted to play the foot once to make the chord change..

how can fix this?

My foot send dual message to command and play chord, when hold and loose.

Sorry for my bad english..
