Very fun synth. It is versatile and comes with plenty of sound design features to work with. If you like using presets, it also has plenty of those as well. It is a bit unstable, and it does seem to be slow when opening, however it is for the most part usable. It also does cause performance issues in FL Studio 2025, but those can be fixed by bridging the plugin.

This is a plugin that I believe is well worth the money you spend, and it scratches my itch for granular effects. It includes many features you would expect to see, all wrapped in a very easy to use interface with good visual feedback. If you are looking for a granular effect that is cheap, easy to use, and doesn't have an invasive DRM or authorization process, this one is perfect for you.

This plugin is, in my honest opinion, one of the best free stereo imager you can get. It creates no phase issues, is simple, fast, and versatile, and also has an incredibly good looking UI, like all plugins by this developer.

Quite possibly one of my most used effect plugins. It is extremely simple and because of that, it makes creating modulation effects really easy. It features a very simple set of controls for panning and volume modulation, and can be right clicked to create automation clips directly in FL Studio, which I very much so appreciate.

Really neat synth, however this synth does feature some quirks that make it less reliable then I think it could be. First, the synth seems to be out of tune by default by about one and a half semitones, requiring the user to manually tune the oscillators individually. The next is the ADSR's release times in my opinion should be able to go much longer then they can. They are too short for creating certain sounds. The last quirk has to do with the filter ADSRs. The ADSR will retrigger for all of the notes when a new note is pressed, as opposed to only retriggering for the note that is pressed, and the release seems to only happen when the next note is pressed. (Let me know if any of this is user error).

I do really like this synths rather intuitive workflow and clean UI. While it does have some strange quirks I still think that this synth is fun and powerful.

This is probably one of the coolest plugins I have discovered recently, and one of the best plugins I've seen created in flowstone. It is very versatile in the sounds it can create, and it features a playful and great looking UI.

The issue I had with it below has been fixed. Thank you dev, this synth is incredible :).

Great sounding synth/organ thingy. It is simple yet very effective, and I love the UI. It also comes with some pretty good organ presets if you are looking for some new sounds to add to your collection.

Sadly the main website is down, but luckily I did upload this to the web archive in case you would like to try it! :3

Much like the previous synth this one is a bit heavy on resources, however this one is better optimized, making it much more usable. It comes with a ton of options including the ability to stack filters and waveshapers which makes this an interesting tool. It also features AM, FM, additive, and physical modelling all in one.

The only thing I like about InfernalSynth more then this one is the orange and teal UI, which I really liked, however I still very much so like the one firefly features, as it is weirdly nostalgic.

While this synth is a bit tough to learn, and the envelopes are the janky synthedit envelopes, this synth is very powerful, and it looks great despite being as old as it is.

Tip: If the plugin does not register using the code, or for whatever reason it unregisters on it's own, open the registry editor, go to "Computer - HKEY_LOCAL_MACHINE - SOFTWARE - WOW6432Node - CK_VST," and delete the "CK-X-Jupitae_Flexoid V1.xx" folder. Finally, relaunch the plugin and register using the code. Be sure you don't edit anything else, as you can cause problems on your computer if you do.

K-Whooms is a simple subtractive synth with an easy UI. It will do exactly what you expect it to, and it will not fail to do those things at any point.
