Notes:
metro 6.22, powermac g4
When you choose "velocity tool" or "bar move tool" in "Graphic Editor" you can't change a drum kit with the left mouse button (all other tools you can use the left button). You can however change the drum kit with the _right_ mouse button with all tools. Not a serious bug but inconsistent.
Repro steps:
1. launch metro and go to "Graphic Editor"
2. make some notes
3. switch to drum mode [keystroke "d"]
4. pick "bar move tool" or "velocity tool" and try to change the drum kit
