change instrument

Hi, I have a percussion kit with a bass drum, and I’d like to move all the music from that line onto a floor tom – what’s the best way to do this? I.e. select all the music from just one line in a kit, add a floor tom to the kit, move the music and remove the bass drum?

In the Edit Percussion Kit dialog, you can select the bass drum instrument and click the “Change Instrument” button (the two arrows pointing left and right) in the dark grey action bar at the bottom of the dialog, and then choose the floor tom instrument.
