Another area of infinite control with software instruments is the ability to edit the actual notes of what you play, deleting notes, adding notes, all within the Editor using the Piano Roll Visual Editor. Double-click the piano's MIDI region to open it in the Editor if it's not already opened. You can scroll down in the top area so you can still actually see your MIDI region, and down here in the Editor we can see all of the individual MIDI notes that were played during the piano performance, so each one of these is one of the notes that I played.
(Music playing) You can hear that. You can always click on these notes to see what they are. You can select a group of notes by clicking and dragging a box around them to group-select which allows you to then either delete them-- I am going to press Undo-- or perhaps even change those notes by clicking and dragging them up to scale. (Music playing) So now we have a different way of the piano starting. (Music playing) One was like this.
(Music playing) So very easy to change any notes that you have. Currently, I recall a mistake happening somewhere in the middle of the song here, and I am going to try to find it here really quick and we'll make a quick edit there as well. (Music playing) There it was. You see that little dissonant chord there? (Music playing) It's because of this note accidentally tapped my finger while I was playing.
So I can just select that and delete it. Now I've got a nice clear chord there. (Music playing) In fact, even this one is. (Music playing) Actually I'd be happier starting with the suspended G and going up to the major chord there. (Music playing) Okay, so that will work for now. So those are two little areas I happened to have heard when I listened back to this a couple of times.
But that always happens whenever I track MIDI performances, is just sort of go back through everything up here in the Editor and watch and listen to see if there is anything that either is a mistake and you can easily fix it, or if you actually want to change what you play, it's very easy to make those kinds of edits. Another thing we can look at is quantizing. So quantizing is almost the same as groove matching except the groove that you're matching is the rock-solid timing of the metronome or the tempo of your song. You choose a degree of resolution that you'd like to quantize.
So, for example, in the quantizing menu here since I have my piano region selected, I can choose which note resolution I would like to quantize to. Now what quantizing means is I select a note value like 16th note or 8th note and all of the notes that I played in my performance will snap to the grid to the nearest one of those. So this is bar 8. This is 1, 2, 3, 4 and our tempo of 4-4. So those are quarter notes and the smaller hash marks are the eighth notes.
So if I look at for instance this first note that I played in this bar, I am going to zoom in a little bit so you can see it just a little better, is closer to the 1 than it is to the E of 1 which is the 16th note after. If I choose 16th note or 8th note in this case, this note is just going to bump right up against the bar. Let's see if it actually does that. So there's my 8th note. I am going to hit Undo. I can select that again and just do 16th note.
It will do the same thing, because this is the closest 16th or eighth note to that note where I played. So what you should do when you're trying to think of what note to quantize to is the notes that you played in your piece, are they largely 16th notes or 8th notes or quarter notes? In other words, what is sort of the predominant rhythm that your part is utilizing? It's almost always the case when you quantize an entire performance is there's going to some places where GarageBand made the wrong decision for you, and you may have to then go in and edit your part further.
In this case, when I am talking about this particular arpeggio that I am playing here - (Music playing) -- those are 8th notes. I'd probably be largely happy with the quantization that GarageBand applies. So I am going to listen to it now with the metronome on. (Music playing) Okay, so that whole section I know is exactly right. That's how I wanted that to be. So I am probably going to end up with some interesting things later on in the song, perhaps toward the end.
Let's take a listen there. (Music playing) As far as I am concerned, those are actually all in time exactly as I just sort of hoped to play them. The only problem with quantizing is that in a sense it's too perfect. So if I don't actually want to play like a computer, I want to add some of that human touch in, that's where this slider beneath this Quantize Note Timing menu comes into play.
If you have it set to Max then GarageBand will move all of your notes exactly to their nearest 8th note without any question. As you slide this slider to the left, just keep an eye on these notes here. They'll start to quiver around a little bit and move out of place, watch. You see them moving? So all the way to off is no quantizing at all and the notes are exactly where I played them. Somewhere in the middle is probably a good place to be. For me, moving it all the way into perfect timing is not really what I'm going for.
I want a little bit of that human feel still in there. So I can come off to maybe say 70%, kind of meets you in the middle between perfectly quantized and what you played. There still may be some areas that we are going to want to edit a little bit later on, but for now that is a pretty solid quantized keyboard part. So I am going to un-solo that track and let's listen to part of it with the song. (Music playing)
