FL11: Batch Changing The Score Notes Duration

Today I'll share one of my experiences about how to change the score notes duration in discrete time.
Here we got a MIDI file. Now let us check this track, "Riff left". I want to change all of the short notes to make them duration doubles.

Original short notes:

And I want to change into this:

Ah, score notes shown on this picture are just 1/200 of the whole track -- even less, you should know that. There are many ways to fulfil it, but I want to know the best way.

My method is:
Step 1) Click the "Snap to Grip" icon then chose the "1/2 step".

Now you should see more closely grid appeared in Piano Roll.

Note: This operation will decide the short notes snap to which grip nearby, chose different type wisely espcially in triple time.

Step 2) Hold the Shift key and hold down the left mouse button to choose a part which included the short notes that you want to make them double. Also this operation will involve other irrelevance long notes, never mind, just do it.

Step 3) Hold the Shift key and select one of the notes tail arbitrarily, then drag it from left to right, now all selected notes should be lengthened. Regardless of the long notes, make sure the short notes snap to grid.

Step 4) Final step. Ctrl + Q or select Tools -> Quick Quantize. Then you should see all the long notes in the selected part will be quantized.

Maybe there're still some wrong duration in long notes after quantizing, undo and back to Step 3, this time we should drag them to close the grip but not snap it. Doesn't work? I have not any idea, you should change the duration manually...

After this operation you can make your further process, this track, for example, is the guitar riff track, I want to double the duration of all short notes, then the velocity modify so I can make them reproduce the palm mute skill.

Some soft instruments, such as Shreddage Electric GT 2, are not like the MusicLab Guitar LPC / Strat, they will not "play" palm mute skill correctly especially when the short notes are too short. Changing the duration of this kind of short notes can we assure our soft electric guitars "play” in expectly.
