After adding music to a track via MIDI keyboard, the material of course needs editing. Changing the "velocity" of individual notes to give a better shape to phrases is easy, and the result is easily tested.
What is much more difficult, I find, is adjusting the length of notes to produce a convincing legato or articulated effect. Although qtractor has a marvellous array of tools for editing midi tracks, it doesn't seem to have an easy way to to do this.
What I have in mind is a tool which would allow one to select 2 or more notes, and then adjust the end time of each of them (apart from the last) to coincide with the start of the next note, producing a legato effect. Alternatively, one could specify the amount of time there should be between each Note_off event and the following Note_on, to produce different sorts of articulation.
It is quite possible that this facility already exists in qtractor and I have just not managed to find it. But if not, is it perhaps something that could be considered for a future release?
