I had a play around with it.
You need to set those settings it for each pad each time you drop a sample on it... The settings dont seem to save; I'm thinking this could be a bug.
Also I've noticed that you have to keep the pad pressed whilst the sample is playing, you can just hit and it plays.
Hopefully we can get some small improvments to this funky tool.
P.S - My first post :)
Just bought X1 Producer, trying to get my head around it.
