Making loops is a simple process in Garageband.\n\n\n\n1) Select the region you want to loop. \n\n\n\n2) Use the command, "Control + Shift + o (the letter, not the number)."Another thing that you can do is go into the 'File' heading and then select, "Add Region to Loop Library."\n\n\n\n\n\n\n\n3) You have two options, either select, "One Shot," or "Loop." \n\n\n\nThe difference is that with "One Shot," the loop is recorded exactly as is, and can't be (as easily) modified afterward according to tempo and key signature adjustments.\n\n\n\nThe "Loop" option, makes it so that the loop will change with tempo and key signature changes. \n\n\n\n\n\n\n\nIt's really as simple as that.\n\n\n\nHow To Adjust Key Signature And Tempo Of Pre-Recorded Loops \n\n\n\n1)Double click on the "Track Region."\n\n\n\n2) Choose the option, "Region." \n\n\n\n3) Check the box, "Follow Tempo and Pitch."\n\n\n\n\n\n\n\nNote that when this box hasn't been checked, the loop won't change at all according to tempo and key signature adjustments. This may be convenient for you later. \n\n\n\n4) Underneath the setting, "Transpose," move the slider to however many semi-tones you want to change it by, up or down. \n\n\n\n\n\n\n\n5) If you want to adjust the time signature, just do it the way you normally do, using the main BPM counter in the top-center of the software.\n\n\n\nThis is where a bit of music theory comes in handy. A change by a few semi-tones will effectively adjust the key signature depending on by how many tones. \n\n\n\nFor instance, if the key of the loop is A Major, and you want it to be changed to E Major, you have to drop it by 5 semi-tones. \n\n\n\nThink in semi-tones, rather than whole tones, because that's how the pitch shifter is laid out in GarageBand. \n\n\n\nIf you don't know music theory, you can just adjust it by semi-tone until it sounds good. It can be done by ear. \n\n\n\nAn important thing to note, however, is that adjusting samples or loops by semi-tones will only work in relative keys. \n\n\n\nIn other words, if the sample\/loop is in A Major, it can only be changed to another Major key signature. It can't be changed to a minor key, because then the accidentals (# and b) would have to change. \n\n\n\nIf you want a starter's guide to music theory, I suggest checking out Music Theory.net or pick up The Complete Elementary Music Rudiments by Mark Sarnecki which you can read more about here.\n\n\n\nElementary rudiments are really not that sophisticated, and a basic understanding will go a long way. \n\n\n\nFor this instance, specifically, you want to learn about the difference between semi-tones and whole tones, in addition to key signatures. \n\n\n\nOther Information\n\n\n\nAnother thing Garageband users often talk about is whether or not it's ok to use Apple Loops when creating music.\n\n\n\nBy the word, "Ok," I mean whether users have to pay royalty fees in case your song blows up and earns money. \n\n\n\n You can read more about that using this link here. \n\n\n\nWhile I can't speak for other Loops created by other companies, from what I understand about Apple, they don't require any kind of royalty for using their loops. I guess it's a gift to their users. \n\n\n\nPutting all of that aside....\n\n\n\nLoops are a great feature in Garageband, whether they're the stock loops that come as a part of the workstation, or ones that you've created yourself. \n\n\n\nWhen GarageBand first launched in 2004, the pre-recorded loops were one of the most talked-about features, with hundreds of presets and samples loaded into the software.\n\n\n\nFast forward fourteen years later, and there are so many loops that come with the software. When I first began using GarageBand, I never considered even using them. \n\n\n\nHowever, after a bit of experimentation, I really learned to appreciate them for what they are. \n\n\n\nThe loops that Garageband offers are convenient for a couple of different reasons, including the fact they can be adjusted to different key signatures and tempos. \n\n\n\nEach loop has the capacity to be used in pretty much whatever song you need it in, rather than having individual loops that are only good for one tempo and one key signature.\n\n\n\nAdditionally, if the music has been recorded using MIDI, one can change the software instrument afterward to create a totally different sound. \n\n\n\nI do this all of the time when creating music. If I've made a melody using the piano, I'll load up a synthesizer, arpeggiator, or a nylon string guitar using copy\/paste with the same music just to thicken out the sound. \n\n\n\nMoreover, as I wrote in my article in changing tempo in Garageband, using the "One Shot" feature can actually come in handy if you don't want to change the tempo\/key signature of your loop when adjusting other parts of the song. \n\n\n\nTips For How To Make A Seamless Loop\n\n\n\nRepeating what I said in this article, creating smooth loops is important for the production process. \n\n\n\nIt can be incredibly frustrating in the beginning stages of learning how to create synchronized samples and correctly timed loops. \n\n\n\nIf the music isn't the proper tempo, time signature, or melodically "correct," it can potentially sound pretty bad - or not to what regular music listeners are accustomed.\n\n\n\nUnless the "incorrect" music is intentional, I imagine you want a song that sounds "right." \n\n\n\nfter a bit of help and practice, users can figure out how to make great sounding versatile loops for all kinds of music.\n\n\n\nIf you want your loop to sound good and synchronized with the rest of your tracks, you have to ensure a couple of things. \n\n\n\n1) The first important thing is to ensure that your track region is only 4 measures. If you try and create loops that are more than four measures, while other loops are 5, it's not going to work out in the way that you want.\n\n\n\n\n\n\n\nHowever, making your loop 8 measures will work, because of the compatibility between the time signatures. \n\n\n\n*Once you've really become sophisticated in your music production skills, you can easily use more sophisticated time signatures. \n\n\n\n2) The next important thing is to ensure that the musical notes fall exactly on the beat or the "lines" - as Garageband has everything laid out.\n\n\n\n\n\n\n\n3) Another crucial detail is to ensure the time signature of the loops are the exact the same, otherwise, they won't sound "correct." for instance, you can't loop a beat in 9\/8 alongside one in 5\/8. It's not going to sound alright if you try and repeat it over and over again. \n\n\n\nFor instance, if you've created a loop at 80 beats-per-minute, and then another at 120 beats per minute, it's not going to sound right.\n\n\n\n4) Using a divisible of an even number will usually sound alright, for instance, if you've created a piece of music that is only two measures, and then loop it for as long as you want, it'll work fine in even number time signatures.Ie, 4\/4, 4\/8, 8\/12, etc. \n\n\n\nHow To Use Apple Loops \n\n\n\nAs I mentioned at the beginning of the article, if you want to use one of Garageband's loops (and Logic Pro X), \n\n\n\n1) Go to the right-hand side of the screen and click on the icon that looks like a hose. \n\n\n\n\n\n\n\n2) Click on it, and it'll bring up countless loops. \n\n\n\nAfter beginning to scroll through them, it's clear right away that there is a ton of them at our disposal. Divided by Instrument, Genre, and Descriptor, you can navigate through the list and choose the one most suited to you. \n\n\n\nUnfortunately, in a recent update, GarageBand changed it so you can't see the tempo and key signature of the loop anymore. \n\n\n\nEdit: After a bit of research, this point is actually incorrect. By going into the Garageband Preferences, then the "Loops" sub-category, users can select the box, "Display Original Tempo and Key."\n\n\n\n\n\n\n\nHowever, I think the reasoning for this is that after dragging the loop into the Track Region, it's really up to the user to choose its tempo and key signature. \n\n\n\nMoving on: \n\n\n\n3) Check out the Genre sub-category, and you can see there are 23 different options, including Rock\/Blues, Country, Jazz, Funk, Indie, Chillwave, Electronic, Urban, House, Deep House, Electro House, and so on and so forth. \n\n\n\n\n\n\n\nPersonally, I love the Jazz section, especially the "Hustle Flutes." It's a great way to add a bit of style and groove to a song that would otherwise sound a bit dry. \n\n\n\n4) In the instrument sub-category, there are 24 different to choose from, including Piano, Strings, Synth, and Percussion instruments. \n\n\n\n\n\n\n\n5) And finally, in the "Descriptors" sub-category, you can select loops according to an adjective, like "Cheerful," "Playful," and so on. \n\n\n\n\n\n\n\n6) Just click on one of the loops to hear it play, and then drag and drop it over to the Track Region. Loops are always in Audio Track (Blue) format. \n\n\n\n7) Now, with the "Enable Flex" function turned off, change the key signature and tempo as you see fit. \n\n\n\nOther Important Things to Consider \n\n\n\nThe loops can actually come in a few different formats, including Green, Blue, and Yellow. \n\n\n\nGreen loops are MIDI-format, in other words, they can be edited and changed as most MIDI music can. Simply drag and drop the little Green notes around as you see fit. \n\n\n\nMoreover, the handy feature of MIDI loops is the fact that we can just change the software instrument track and then have an entirely different sound. \n\n\n\nAudio, on the other hand, can be edited but only in terms of key signature as well as Tempo. In other words, they are previously recorded audio snippets. With that said, Audio Loops typically sound quite a lot better than MIDI loops. \n\n\n\nAnd Yellow Loops are pretty new. They are drummer tracks that can be edited for fitting into your music specifically. \n\n\n\nAnd finally - this probably goes without saying - you can change the length of each Loop as usual by just hovering the cursor over the loop, and dragging it to the desired length. \n\n\n\nIf you wanted, you could build an entire song purely with loops. While some people would seriously question that sort of thing, I don't there's anything wrong with using pre-recorded loops as a way of creating music. \n\n\n\nIf you can create something unique using the building blocks another person created, have at it. \n\n\n\nThat's all for now.
