Join author Brian Trifon as he shows how to improve music and audio productions using virtual instruments in Logic Pro. This course tours the program's virtual instruments, including the ES2 hybrid synthesizer, Sculpture physical modeling synthesizer, EFM1 FM synthesizer, the EVOC 20 vocoder, the Ultrabeat drum synthesizer, and the EXS24 sampler, and shows how to achieve various effects with each instrument's parameters. The course also covers working with oscillators and filters, understanding signal flow, creating custom synthesizer patches, adding effects, synthesizing speech, creating a library of custom sound samples, and much more.
Virtual Instruments with Logic Pro will be updating on a monthly basis, eventually covering all the virtual instruments in the application. Look for the latest movies here and on the lynda.com blog.
When you first open up EXS24, it opens up with no sampler instrument loaded. However, if you play the keyboard you actually do hear sound. (music playing) It just has a sine wave. If I want to actually load in a sampler instrument, what I can do is click on this Sampler Instrument menu right here and that brings up my whole library of the EXS24 instruments. So here are some of the factory ones that just come with Logic. So I am going to select EXS Strings 2. So it loads in all settings in this parameter window, and I can play on the keyboard. (music playing) There we go. Sounds like strings. (music playing) So if I want to navigate through other EXS instruments, what I can do is just press this plus and minus button to the next or go to the previous one.
So what if we want to make our instrument, just a simple one-zone instrument? What I can do is actually just set this back to No Instrument so there is no sampler instrument loaded, and then I want to reset the settings in our Parameter windows. So I am going to go the options menu and go to Recall Default EXS24 Settings. So now it's back to its original state. So I will open up the Sampler Instrument window, and what I want to do is create a zone and within that zone I can load a sample, and then we can play back.
So I am going to go to the Zone menu and create New Zone, and here it is, and you can see down at the bottom that there is a zone that ranges across the entire keyboard. If we look here, here is our key range: C-2 to G-8. So now what I need to do is actually load an audio file into that zone, so we can play it. So if I go under this Audio File column, I've got this Load Audio Sample. So when I bring that, it brings me to the finder. Then I can go through my hard drive and just find any audio file and load it in. Or what I can do is actually just double-click right here and do the same thing, load an audio file.
One way that might actually be easier though is if you have audio files in your range, you can just drag and drop. So let's delete this zone. I've just got it selected here. I am going to press Delete. So now it's gone. So what I will do is I am just going to move this, and you can see in our arrangement that I've got this TrifonGrowl file. So I am just going to take that and drop it in here. So what that does is it creates a zone across the whole range of the keyboard, but it has this TrifonGrowl audio file loaded in it. So now when I play on the keyboard, you can hear I've got that audio file.
It tracks pitch and everything. But notice when I play up higher on the keyboard that it plays it back faster. So it's tracking pitch, but it's changing the speed of the audio, and that's just one of the side effects of re-pitching audio; it's just going to slow it down or speed it up, depending on whether you're playing higher or lower. So in order to figure out where it's going to actually play back at its original pitch, what I have to do is keep track of what the root key is. That's what this assignment is here. So here we have got all of our pitch parameters. So root key is where it plays back at its original speed and pitch.
So in this big zone that spans the entire keyboard, it's C3. That's where it's going to play. Now if I want to adjust the range of this zone so I don't want it to span the whole keyboard, what I can do is adjust that here. Under Key Range, I can drag up and down. So I can set the lowest note to something different, like let's say C2, and the high--let's just have it be the C4. So we have got sort of an octave in each direction from the original pitch. Another way I can edit this that's probably more convenient is you just drag down here. You can just literally move each end of the zone to wherever you want.
I can also move this whole zone here to a different range. I can just click in the center and drag it. But notice that when I do this, my root key--so under the pitch column--it's not changing. So what's happening is that I've moved my zone into a different range, but the root key is still at C3, even though the C3 is now the very end of this zone. It's the very top end of it. So usually you don't want that. Usually you want to move the root key while you're moving the zone. So I can set this back to the range that we had before, so that we've got C3 in the middle. And now if I hold down Option and I move the range for zone, you can see that the root key moves with it.
So now that we have explored how to make a simple one-zone instrument, let's take a look at how we can make a multi-zone instrument.
