Sound Design course for SFX (film, video games). Especially with synths.

Here's a brief list of some things:

- Akash Thakkar youtube channel + podcast
- Zapsplat gold ($6/mo., use as needed)
- Pixabay audio
- Sonniss GDC free sound packs
- Ben Burnes https://ben-burnes.gumroad.com/
- Freetousesounds, tons of different ambiences and some more foley-oriented sounds

There are some helpful reaper actions and custom actions that can be set up to make things like chopping + cascading audio clips across tracks easier, batch export options, hotkey-loadable fx chains, etc. I'd also recommend birdbird's Global Sampler as a project default, and a portable install specific for sfx (separate from composition install, unless you don't even use Reaper for composing) so you can turn off pitch preservation when stretching samples in default project settings among other sfx-oriented global defaults.

Thanks a lot...
I did discover the Akash Thakkar youtube channel previously and yes, it seems interesting.
Regarding the rest, it seems to be mainly samples/library, and I would be more interested in doing my sounds by myself with synths (I already have some nice libraries, and I know how to make my own sounds through recording).
I rarely use Reaper but I'll investige what you advise...

I think Negativist and someone like this https://www.youtube.com/channel/UCFFFxq4M1ZWXw_vLoTfN4BQ may have some ideas worth checking out. I haven't gone looking for particularly good courses.
