I have a drum map on track 1 piano roll. How do you change the color of the "note" It is a blue color that when selected doesn't show up good for me but I've drove myself nuts trying to find where to change it in preferences/colors Anybody know?

This reflects the colour of the clip notes - set it via the Clips tab in the Inspector (Track View)

It's the "forground" colour - isn't it?
 
This is also one of the settings in Preferences -> Colors that actually works! It's forground colours for MIDI clips. (MIDI background colors does nothing now - as there is a different setting for background clip colors of audio AND MIDI clips)

It makes sense that this is one of the few colour options that does work, as you can access it via the Clip
Properties as well as in Preferences.

So under preferences /colors there is a selection called clip notes? No wonder I can't find it. Clip notes? I was looking for midi drum map or something. It's not under midi tracks. I already tried changing all them.

There are 2 ways of doing this.

1 - in Track View, select the Midi track you want to change colour
2 - Make the Inspector visible (press "i")
3 - Click on "Track"
4 - Under "Colors" you have a separate choice for Foreground & Background

Or..

Hit "P" for Preferences
Go to Customization > Colors > Midi Tracks

Here you can assign colors for Foreground & Background in groups of 10

I tried changing the midi tracks in pref/colors and couldn't get Drum mapped notes to change. I'll try the other way thanks!!!
