simply do not work for me. I have clicked, right clicked, control clicked the flag, the line, the region… nothing works.
Am I missing something simple? I’m importing MIDI files into ardour and they come with lots of patch changes sometimes. Getting rid of them all is a huge pain.
Are you in internal edit mode? (Press “e” to enter this mode). The default mode is “grab” or “object” mode, and in this mode, all operations with the mouse are interpreted to apply to regions, not any data inside of them. You need to be in internal edit mode to alter MIDI data (or draw mode, for the same reasons).
