If you’re an old-school 80s synth or sequence of person and you probably know what an arpeggiator is but if you don’t then you’re in for a treat because in this GarageBand quick gem I’m going to show you how to use the arpeggiator here in GarageBand on the iPhone or the iPad so let’s go hi my name is Pete.
This is studio live today and if it’s your first time here this is where I help you create record and release.
Your best music and in this particular series GarageBand quick jams in just a few minutes I show you all about a very cool feature that we have right here in GarageBand iOS and in this case we’re looking at the arpeggiator to create those cool arpeggio sounds so let’s dive in to GarageBand here on my iPhone right now and take a look here we are in GarageBand on my iPhone.
Now this is a quick gem so it’s going to be a crash course in how.
To use the arpeggiator now we can use the arpeggiator with any keyboard.
Sound except some of our alchemy synth sounds that I have the arpeggiator already on them so.
Let’s tap on more sounds here and I won’t use my classical ground we need some sim to really give our our pga tour a test here let’s use the helix sound so we’ll jump into helix.
Here now the up engine is already on we’re gonna turn it off because we don’t want that let’s hear what the sound sounds like to begin with very cool classic 80s synth so if you want to use an arpeggiator we tap on the arpeggiator button which is up here on the top right.
Between our chord strips and our scale we’ll tap on that one there and then to turn on.
The arpeggiator we tap on run and now we’ve got a few options here we have our note order so I don’t order can be either up down up and down random or as played we’ll leave that on up for now we’ll tap arpeggiator to go back our note.
Rate can be anything from a quarter note up to a thirty-second note and it can be dotted or a triplet as well we’ll leave that on the default here which is a sixteenth note and go back to our arpeggiator and then finally our octave range can.
Octaves we’ll leave that on our two octave range to.
Start with we’ll hit done and now let’s just tap on c3 we’re gonna tap and hold and see what our arpeggiator actually does so all it’s doing is an octave.
C3 and c4 and it’s just going back and forth it’s going off at the moment so it’s going to do doo doo doo doo doo doo doo so if we tap on arpeggiator here again we can change all of that by changing all their arpeggio settings which we’ll jump into and give you a quick look at right now okay let’s go back to our arpeggiator here.
Now let’s play around without a note order so we’ve shown you what up does let’s turn this two down and hit done now for these ones I’m gonna actually hit four notes at the same time just so that you can hear the difference so if I tap AC chord.
Here you’re gonna hear this so you can hear it starts at the top and it goes down all the way through two octaves using that will tap it again now let’s.
Change this up to up and down hit done let’s do our same C chord so now it goes all the way up and then all the way down across those two octaves let’s tap it again and we’ll go random and now not surprisingly we get a random patent and finally if we tap on this one and we go note.
Order we can go as play so now it’s going to be the order in which we tap them so I’m gonna very carefully do a C chord from the bottom to the top.
And see if we can get this in the right order that was clearly not a seeker but I’m gonna leave it in because it was a bit funny that was some other chord but yes.
You can hear that whatever note order I tap them in is the order of the app hedgy Oh we’ll be okay let’s jump back in and take a look at our note right now so at the moment we’re in a quarter note which sounds like this but we.
Can change that lets tap it again and make it an eighth note and we’re gonna sound like this and once again we’re back.
At our two octave up sounds and we’ll tap it again we’ll go to the sixteenth note we’ll tap again and hold and finally we can make it a thirty-second note and.
Look we can do a dotted version or.
A triplet version as well but you can play around with those ones let’s just go thirty-second note when you get up to 32nd note if.
You start playing chords you can get some pretty cool sounds loving it and finally let’s jump in and take a look at our octave so our octave range we can make it one octave which is pretty boring if you play one note but works well if you play a few more notes or.
We can go anywhere up through two three or even four octave let’s bump it.
Up to four octaves play a chord and see what we got here very cool now when you’re recording an arpeggio using the arpeggiator a.
Actually hold down your notes just before the recording starts to make sure that the first beat.
Hits right on the first beat I’ll show you what I mean here I’m gonna hit record I’ll hold down the notes and you’ll see what I mean and there.
You go you can hear that the first note hits right on that first beat whereas if I hit them at the same time it might be slightly out of sync and the other option we have when using the arpeggiator is that you latch option so if we just tap and hold on a key at the moment as soon as we release it the arpeggiator stops if we turn on the latch.
Key and we tap a button without holding until we slide off that latch the arpeggiator continues so if you want.
To be able to play your opit without holding down the notes you turn on the latch and then.
If you just tap the notes it will continue playing until you turn that latch back off and one.
Final tip here and that is to be aware of both your time signature whether you’re in 4/4 3/4 or 6/8 time and also as soon as you start getting into a note rate that is higher or a large octave.
Range you’re gonna start getting out of synch with your time signature I’ll show you what I mean.
Record hold down three nodes and you’ll see how quickly I can get out of sync here so you can see there you’re going to have to use a little bit of mathematics or a little bit of trial and error to work out which type of arpeggio is going to work with which particular time signature here in GarageBand and there you go how cool is the arpeggiator here in GarageBand if you’ve got.
