Muting single midi notes?

[Jellybeantiger]

How?

[Light Grenade]

Press F10 until the erase tool changes to 'M' and then click the note you want to mute. 

The colour will be stripped from the note once muted.

I just Shift+R-click on the note, to Mute it.  (R-click on its own, Deletes the note).
