My favorite for a while was Crystallizer by Soundtoys which I used heavily on my first album, but I'm more of a fan now of Glitch2/Effectrix2 (basically the same thing)

In terms of instrument VSTs I've been enjoying Diva recently

Zenology. It may be a bit shitty but it has a ton of anything, a lot of variations of different instruments and also customization. It also has a lot of 90's synths

VST-wise my heart goes out to RX950 by Inphonik , the purpose of it is to emulate the sound of an Akai S950 sampler . Its absolutely perfect for shit like boom-bap , old school contemporary R&B as well as New Jack Swing (NEW JACK FOR THE WINNNNN) , jungle , early DnB nd jus other shit frm them old eras that utilized old school Akai samplers . Great for lo-fi shit too . The brightness , the crunch , and the punch this thing can give puts the biggest smile on my face , i esp LOVE it on drums

VSTi-wise , my number 1 favorite is Atmosphere by Spectrasonics . Yes im aware that all Atmosphere patches are in Omnisphere but ITS NOT THE SAMEEEEE bro them shits for Omnisphere is jus rebuilt frm the ground up nd me personally it jus sounds either hella sterilized to the point where it loses its glam or its jus too off bro its so weak . Nothing beats the real Atmosphere

A runner-up for VSTis that i jus couldnt resist to mention would be Alchemy by Camel Audio (now ig the VSTi is Apple's property but wtv lol ion got a Mac nd i couldnt care less abt Logic). Purely godlike but if i wasnt so giddy on the charm Atmosphere brings me then id def wouldve put Alchemy on top without further debate . Im hellbent over the Roland V-Synth nd when it comes to something like Alchemy , which is a spiritual successor to the V-Synth , im immediately sold on it . Theres so much sounds n options already there for u nd it has an almost infinite room for creativity , and the best part is that its easy to get into
