Round one listed some packs of free VST plugins with the added purpose of ease of availability and installation so you don't have to worry as much about missing plugins when loading old tracks into your DAW. Today's list includes a few individual oddball plugins that have a similar purpose, but aren't quite the RSTLNE of DSP.

Xfer Records OTT

Basically, you can take any channel of harsh sounds or an individual sample/instrument, drop OTT into the chain, and not worry about how it fits into the mix, because it will simply always be OTT of the mix. After meddling with with the downward and upward compression or not, you can then use it like a DJ boost or kill EQ to cut the high, low and/or mid. Secretly, I'll even use it on the master channel at 1% depth or so to use the upward compression and pull a little bit of the more subliminal noise out of a mix.

Arguru's Stardust

Stardust had almost an identical purpose for me as OTT before I found OTT. It provides a way to take a channel of overly dynamic harsh or soft sounds, usually created after slicing up IronChefOfMusic ingredients, and gets everything into the same space. It doesn't have upward compression, but the multiband compression only really works well with an attack of at least five milliseconds, so the result is you will get highly boosted transients, but the rest will be will be smoothed out, which can create some uncannily weird sounds depending on what you put through it.

Granaliser by Morfiki? 👎

I used to really like the Granaliser plugin, the "morphing" options are extra neat, but it tended to be a bit crashy, it's only available as 32bit, and even though there's a "kids" version, I don't really want to talk about it.

👍 Argotlunar.

Get Argotlunar instead. It is a great go-to, no-frills, granulator, also a great tool for learning the science behind granular synthesis.

Previous: Some of My Favorite Best FREE VST Plugins of Any Year but 2020: Round 1

Here are some free VSTs I use all the time.

mda-vst

They're also now available in 64bit!

This is one of the few free swiss-army sets of plugins that I'll always install as soon as I reinstall an OS. There's no installer, they're GUI-less, and among the basics, like delay and limiting, there are some uniquely useful and creative plugins like Tracker, which has four types of envelope following and re-synthesis, and DubDelay, which is nice to use subtly with a LFO on the delay time.

What's great sticking with plugins that are in free packs like this, with no installers or other dependencies, is that you can be up and running with your old tracks and projects after reinstalling your OS and/or favorite DAW on a new system, without worrying about managing your usernames, passwords, 2FA, portals, suites, plugin managers, etc from services like some I don't really want to mention. It also makes them more future-proof, because who knows what will happen when Native Instruments HQ gets nuked and you want to install Fruity Loops on a used netbook you found in a dumpster.

GVST

Also available in 64bit. 
(why do I still have the 32bit versions installed here?)

For the same reasons as above; no installer, swiss-army, both standard and fun effects, get up and running fast so you don't have to find and install granalizer just to correctly render a track you made seven years ago.

Some of my favorite from this collection are GGrain, a granulator, GSnap, a quite functional (possibly T-Painful) pitch corrector that also supports MIDI input, and GGate, which I quickly can toss on any external mic or instrument input.

MeldaProduction
MFreeFXBundle

Requires using the installer, and some are free to not pay for.

MeldaProduction's free vs pay options within the installer creates a vague experience compared to the 100% free mda-vst and GVST plugins, but the free options that come with the installer provide a decent set of useful necessities, though the free plugins in free mode have a little nag at the bottom that my brain is now fine with ignoring. The one I use the most is the MRecorder since I'm perpetually routing all of my system's audio through my DAW, and often want to sample a movie or recording I'm playing in another app.

MRecorder has a nice feature that appends the time to the end of the filename so you can record to multiple separate files consecutively.
