elad770,
The way the Multi Pads work is NOT a bug. I had a conversation with Yamaha Tech Support years ago about how the Multi Pad buttons work. I suggested they should work differently, but the response was... sorry it's not how you think they should work, how they work; is how they work. (get used to it)
I didn't create the original Pad Stopper file, someone else did... I just made a "new improved" version of the Pad Stopper based on my knowledge of how the Multi Pad file is structured. Basically, there is a single note that plays silently one time and then the Pad stops. Yes, it works very well when used in registrations, but takes a bit of time to setup. Registrations are the center-piece of the arranger design and a very powerful feature that can be used many ways for different purposes besides arranging a piece of music.
