Chord pads, midi, plays continues

First thing…i like what you did with this release.
To be a good suport user of cubase now i come to you with issues.
Chord pads: i started to play with them on a new ideea, and i was not able to do anything because:
i have a m audio axiom, and when i hit C1 to play chords( C MAJOR IN THIS CASE) it plays the chord continues, if i play another note it playes all over the C major…and so on. Madness
I did all the setup in the device setup for that, like i am using this controller with the 7.5 version with no problem, with no results.
Hope to find a solution for this problem.
Thank you!
