So I like the sound that we have started. (music playing) That's pretty cool, but it'd be really great if we could create some variations on it. It's one thing that's great about EFM1 is it has this Randomize feature that allows us to add just a certain amount of controlled randomness to our preset. The first thing I want to do, if you actually make a sound that you like, this here, you are going to want to save it as a preset so you don't lose it. The way you can do that is you go to this menu up top, the Preset menu, and go to Save Setting or Save Setting As.
Usually Save Setting As is a good idea because you want to change the name. So when I do that, what I can do is just type a new name for it. So I will call this CoolPresent. Usually it helps to give things a meaningful name. In this case CoolPreset is meaningful to me. Okay, so now that we have that, I want to make some variation on this. So what I can do is I can tell the amount of randomness I want to add to my current preset. So an amount like 7 percent is actually pretty good. That's the default they have set here.
Because it's enough that we'll hear the change, but it's not so much that it would be entirely different, because this Randomization parameter can go all the way to 100%, where if we click the Randomization button at the 100%, it's a completely new, entirely different sound that's unrelated to your original one. So let's try adding 7% randomness. So I clicked and you saw that everything moved a little bit. So now I can hear that the harmonic is different of the modulator. Everything sounds a little bit different. Let's try it again.
It's definitely different, but still maintains a lot of the character of this original sound. So there I did it again. This is nice. It's really cool because sometimes you'll find unexpected things that you wouldn't even come up with, and also sometimes sounds that don't work out at all. (music playing) So we can increase this even more. So let's try 50%, somewhere around there. Okay, so first I have to click the Randomize button, and you see that some knobs and sliders moved around. (music playing) Okay, so this is definitely much different territory than what we had before. It's pretty cool.
Let's try it again. (music playing) So, yeah, much different. (music playing) And of course, if we do a 100%, it's just going to be entirely different. (music playing) If you look at the ratios of Carrier or Modulator, 11 and 14, much different. Notice that if I press this a bunch of times, everything changes except for a few parameters. (music playing) So you can see that everything is changing except the number of voices, the global transpose, and the global fine- tuning, but everything else will change.
So sometimes what I will do is just hold down a node, press the Randomize, and sometimes you really luck out with some interesting sound effects and things like that, like this right here. And of course, if you come up with the setting you like, make sure to save it as a new preset. So what I can do is go back to that menu up top, go to Save Setting As. We'll call this, this is our Alien Sound Effect (AlienSFX), and we save that, and then what's great is it shows up in the menu in future.
So here we have our CoolPreset. Here is our new AlienSFX. So if want to go back to the CoolPresent, there, go back to it. (music playing) I've got that and we've got our new one too. Once we've got some presets and things are sounding good, it's really great to be able to assign a MIDI controller to control the FM amount so that we can actually test some things out and be more expressive with playing on the keyboard. So we'll check that out next.
