midi keyboard articulations

Bug:
In note input mode, selecting an articulation (e.g. staccato) in the top menu, does not have any effect when entering notes with a midi keyboard. (as opposed to entering the note with a computer keyboard or mouse where the articulation is applied to every entered note)
Can somebody confirm this behavior?
I am using a Akai Apc key 25 midi keyboard (i have mapped the launch pads to computer keyboard shortcuts, using the linux tools aseqdump and xdotool, and amidi for controlling the leds)
