One of my favorite parts of producing music is finding new sounds to use. Sometimes it's fun to try to take a sound and change it. You can even use a synthesizer and create one from scratch. I've been doing that more lately. There's even a Coursera class from Berklee about sound design I've been taking.
Any part of music that lets you be creative as possible is incredible to me. Justen Bieber released "Where Are You Now" in 2010 and was produced by Skrillex and Diplo. A few years later, I saw a video of Skrillex and Diplo explaining how they created the song, pretty much just breaking it down and talking about their process. There's a part of the song that sounds like strings mixed with a slide whistle. And they explained how they created that sound out of Justin's voice. I thought that was so amazing, and I wanted to try it for myself. The process, as they explained it, was to first pitch his voice up. Then they distorted it a bunch of different ways until it sounded like something they wanted to use.
I tried to do this too, but sound design isn't a strength of mine yet. There are so many areas of production, and this is one I'm starting to master now. I think the path I've gone on is a good one. I learned about the tools and sounds that came stock with FL Studio, and now I can create my own.
Many VST plugins in FL Studio and other DAWs have settings you can change to design their sounds. You can change the attack and release, add delay and change the curve of the wave. You can make it sound more hollow like a clarinet or more like a violin just by doing some of these things. I haven't created a brand new sound from scratch that I've used yet, but I'm working on it. I've mastered the basics, and now I feel I can do so much more. I can make something no one has done before or try something no one has thought of. Or at least something that hasn't been done in a long time. So, for now, I'm just going to keep going and see where it takes me.
