Modified volume songs?

Hi all,
I would like if it is possible to modified each elements of songs?
For example: on song (Rock-beat8-simple var 2b) I would like to lower the volume of the ride, is it possible ?
thank you

It would be easier to edit the drum kit, as otherwise you will need to edit the all the midi parts with a ride cymbal and lower its velocity. Editing the drum kit would mean you just lower the volume of the ride cymbal in the specific drum kit, of course it will affect all songs you play with the kit - unless you save it as another kit thereby making a copy. My videos should help with the process.

ok, so I must doing a kit copy for modified?
