HugoV,
Your english is very good.

To address your problem, there is no general bend parameter for the JV1010. This is because it is more versitle to have different bend parameters assignable to individual patches. You can, however go to each patch you would want to use and set the bend range for that patch, then store it to a user patch.

In order to do this with the sound diver, on the top left of the newly booted screen, click on "windows". Then click on "open editor" and patch parameters will apear. On the uper left you will see bend up and bend down. The range for bend up is 0-12 and bend down is 0-48.

By the way, you can't open up the editor unless your JV1010 is hooked up either through midi or the milti-pin connector.

Good Luck.
