Telmo, I was thinking more in the way of a tutorial for the Yamaha users here. While the simple back and forth is fun here, nothing beats a nice step by step, as if you were explaining to people that DIDN'T know how to do what you are doing...

As I'm sure many don't, going by the lack of user demos here with your depth of usage of sampled multipads. Perhaps if you could SHOW how easy it is, more might be interested in using the feature. It certainly adds the gloss to your demos, and takes them to another level. All the kudos here show how much we all like your work. Perhaps you can help some of us with those features to make better use of them?
