Your post is a little confusing

. It may be an idea to include the question in your language too, below the english question if english is not your language. There are forum users from many countries.
I have a different version of JJOS, but when I am editing in chopshop the sound still depends on how hard you hit the pad. Have you tried switching FULL LEVEL on.
If this is not the problem then try asking the question again in a different way and give a bit more detail if you can.
Also, you have a 250GB hard drive. I understood that the 2500 could only go up to 120GB hard drives before there may be problems with saving and loading. You might have to check this out.
