Piano Roll acting strange

[Il Sorpasso]

hello
these are my first steps with Usine, after reading most of the manual. I'm trying to have Battery playing a sequence I program on the piano roll. It is very simple, I just started with a kick playing on the beat. Here is a screenshot (big image) :

What is happening is that the first three steps of the cycle are doubleplayed, (2 hits at the same time, with a tiny delay of several ms).

and I really don't understand why... Any idea ? Is there something unclean with the midi management ?

thx in advance !

All post can be useful.
After you post I've decided to check the pianoRoll deeper. Result, the actual version is not so clean...
I'll post a new update (2.81c) which correct a couple of small bugs.
