This sweet little app appeared on the App Store last night, and I’m totally blown away. It’s called Beatmaker by Intua [App Store link] and it’s the first attempt at a full fledged music creation program for the iPhone.
As you might know, I don’t have an iPhone, but I do have an iPod touch. This actually only means I have to use headphones for this program. In its current state it doesn’t record via the built-in microphone on the iPhone, though that’s probably a planned feature for a future release.
The main screen is pretty straightforward, and allows you to save or export your work. Beatmaker features a “file system” for organizing samples and projects.
The pad view is very fun to play with, and allows recording with automatic quantization. This feature is great for a mobile pre-production app like this. It also makes using it as a performance gimmick all the easier.
The sequencer view is both yummy and well-designed for touch input. Obviously it’s a bit toned down from Logic or Ableton, and only 16th note grids are available but the loop-based song creation is actually very effective for coming up with sketches and ideas.
The effects “rack” takes an obvious cue from Reason for its design, and features Reverb, EQ (lo, mid, hi only) and Bitcrusher (which I was surprised to see even though it’s a technologically lightweight plugin).
Beatmaker is available for $20 through the App Store for iPhone and iPod touch. This price is a bit higher than other programs, but unlike most of the apps which are toys for your device, this one could actually be used for creative/performance purposes. Definitely check it out!
This is a request of many GarageBand users who have moved beyond the basic loop and MIDI functionality of this program. This is a technique we use in Level I music tech.
…click read more to start!
Let’s start by defining a few things about how GarageBand handles music regions in the arrangement pane.
Above is four color-coded loops which each have different meanings:
Green: MIDI data
Blue: Library loops
Purple: Recorded material
Orange: Music from a file (i.e. dragged in from iTunes
Green and Blue are sensitive to tempo and pitch changes, while purple and orange are not. What we need to do is take something from purple/orange (we’ll use orange for today’s example) and change it to Blue. It’s impossible to convert any audio file to a green MIDI loop. Don’t even think about it because it’s just plain wrong.
First step is to identify the loop you want. GarageBand can make loops out of any clip that is an even number of beats above 4. (For instance, I can make a 4 beat loop, a 12 beat loop, etc.). For the sake of the tutorial, I’m going to make a 4-beat loop out of the beginning of “Crazy” by Gnarls Barkley.
Making loops is a type of sampling, and a good rule for sampling is to start with a clean peak – no silence at the beginning. Otherwise there will be a delay before the loop plays.
I’m going to zoom in,
turn off snap to grid (in the control menu) and drag the bottom left corner of my region until I don’t see any flatline.
After you make this edit, scoot the loop all the way to the left.
Now we’re ready to do some real work.
Zoom back out, and turn Snap to grid ON – you’ll need it on!!!!
Click the “Cycle” button and make a cycle region from the beginning to measure 2. This should snap to an even 4 beats. The bar should jump slightly as you move it – if you are able to glide it smoothly, turn snap to grid on!!!
Now is where you use your ears. We’re going to cut the loop from this region, so we need to make it sound exactly how we want it. This is a real easy clip to use – it should just sound like even notes if it loops correctly.
We’re going to adjust the tempo to fit our music in the yellow loop region. “But wait! Won’t that make the music sound funny?” Good question. Actually, it won’t – since orange regions aren’t affected by tempo change, this will basically tell GBand how fast the ticks are going by in relation to the song. Now get back to work….
Adjust the tempo to fit all 4 peaks within the 4-beat cycle we made.
Hint – the tempo isn’t 120 (select below for answer)
the answer is 124
Now that the loop sounds right, we’re going to make the incision. Put the timeline cursor right at the “2” mark, and go to Edit -> Split (you can also do this with Apple-T).
Click somewhere else to deselect, and select the nice little 1-bar chunk. Go to Edit -> Add to Loop Library…
This brings up the menu where you can describe all the metadata for your loop. Being detailed here will help you find your loops in the future. Now, here’s the test if you did it right:
Notice if it says “Loop” or “One Shot”. Does it say Loop? Good! Oh wait, what’s that? You say that Loop is grayed out and you can’t click it? Guess what? YOU DIDN’T HAVE SNAP TO GRID ON!!!! (or it was an odd number of beats – either way hit cancel!) If you don’t make it into a loop, it won’t get the benefits of being a loop, like sensitivity to tempo and pitch change, and well, that’s kinda the point!
Now, you should be able to search for and find your loop in the loop library. To just look at a library of loops you made, click the menu above the library and change to “My Loops.”
Now start sampling and remixing away! Let me know if this tutorial was helpful to you!
