Here are different resources that I use to make my music!

(Note, I'm not sponsored or anything (I wish) by any of these and I only recommend tools I use myself (or are noteworthy/previously used). I'll also try to only recommend free tools unless something is insanely cheap and/or worth the money).

⭘Kilohearts Essentials. One of the easiest sets of effects ever, super useful and can easily replace your DAWs stock effects if need be.
⭘Vital Synth Hands down one of, if not, the best free synths out there; has additional tiers; the tiers get you more wavetables and presets, so not overly needed but definitely worth it if you want to support the dev.
⭘Kerovee. An easy auto-tune/pitch correction vst. Gives a different character than other freeware tools of its nature.
⭘All of Voxengo's free offerings. Especially SPAN and Correlometer which I use for mixing and mastering all the time.
⭘GVST's offerings. I use, mainly GGate as it's a simple enough gate and GTune to see if my songs are in key.
⭘Missortion. A great distortion to use on kick drums.
⭘Geonkick. I don't really use this that much , I tend to use samples and then pass them through loads of distortion; however, a proper free drum synth nevertheless!
⭘ArX. A super useful tool to fix mono-compatibility in your mixes. I use this on pretty much every mix (oops).
⭘ValhallaSupermassive. A good one-stop shop for reverbs, delays and general atmospheric noises. Presets are great by themselves and a more than enough of a reason to add it to your arsenal.
⭘Halley Labs/Comet's Tail Toybox plugins. A collection of cool and unique plugins made by the mind behind Lapfox Trax, Emma Essex.

Other than that, I use FL Studio (latest version) to make my music. I might add all the paid plugins I use at some point; but I feel that promoting free tools is a better way to get more people into music production.
(⭘If you did want a free DAW though, I used to use LMMS. The transition to FL Studio was pretty smooth.)
