Change volume of one note in drumtrack.

It might be easier to do that "editing" in the synth itself. 

In the drum synth, IF, the synth allows control of the individual parts of the kit, you could simply go in to that kick drum and turn it down. 

I don't use any of the drums that come with MC as a general rule, but I do know that in Jamstix, which I do use, I have complete control of the volume of each part of the kit.   Most drum synths will allow this level of control.

If you are using SI-Drums I believe you can control the volume in the GUI of the synth.... not in the midi track.

As a side note here: In the midi track you can edit the volume, velocity, and other parameters of the notes. I'm not sure if there is an easy way to lasso all the kick drum notes in a midi track (percussion format). One thing you really don't want to do is to set them all to the same exact volume and velocity. No live human plays that perfectly. 

However,,,,, to edit on a note by note basis.... in the midi track you can left click on a note to open that note's Note Properties Window. You have access to all the note's properties.... start time, end time, duration, volume, velocity, pitch...... using this on an entire track would be tedious. I don't know if copy & paste would save a bunch of time.... it's easier in the synth to set a maximum level. 

hope this helps you a bit

I wonder if the normal Windows procedure Ctrl-click works in piano roll? I don't remember ever trying it myself.
That way you could select only the notes that are too loud or low and edit their velocity in "Scale velocity". That would propably still leave enough "live-variation" in the dynamics.

I don't work in PRV but..... correct me if I'm wrong (those that do)....

Can't you also lasso the notes and then insert/draw a velocity envelope for those notes to give them some variety?
