Dexed, Operator and Wavetable for digital synths. Also have an old Massive license that’s fun to use on occasion, and I recently got Largo on sale for when I miss my Blofeld.
Synapse Audio The Legend, U-he Repro, and TAL u-no-lx cover the analog stuff
I use Ableton’s stock samplers the most but bought TAL Sampler earlier this year and need to dig into it more.
For effects… lots of Ableton stuff, most notably Echo used in any way other than as a delay.
I got Soundtoys Little Plate when it was free, and the only others I’ve felt the need to spring for were Decapitator and Little Alter Boy. Decapitator is great but I still use Ableton effects for saturation/distortion most of the time.
Valhalla Delay and VintageVerb are amazing and are primarily what I use for delay and reverb. I stopped using my OTO Bim and Bam after getting them.
I use Melda MAutoPitch for a free autotune plug and it does the trick.
Goodhertz CanOpener gets used at the end of my master track when I use headphones. I use their TiltShift plugin a lot, and Lossy is fun for mangling audio.
I think that’s pretty much it. I try to keep my collection small and focused, and feel happy with what I have now. Fabfilter Pro-Q 3 is the only other plugin I’ve thought about getting but EQ8 has been fine for me thus far.
