Plugin Alliance has big sales once again, I subscribed to Mix & Master bundle a while back and there is a ton of stuff I haven’t even tried yet, but the overall quality seems excellent throughout. The bundles are pretty good value, and you get kind of cash-back voucher per year, so combined with the big yearly sales it can get you quite far even if you don’t want to subscribe for years. Excellent payment model in my opinion. Some of my favourites so far are:
Opticom XLA-3: Such a great deep sound, even on pretty tame settings adds a lot of character to the low end. Really suits darker and noisier sounds.
Black Box HG-2: Really versatile and good sounding saturation/distortion. I’ve been a fan of Klanghelm SDRR for years, but this has pretty much replaced it for me. I really dig the high end especially. Great from individual tracks to master bus and everything in between.
bx_opto: Another optocompressor. Cleaner sound compared to the opticom. Super quick and easy to set up, pleasant transient response, such a useful simple compressor.
bx_townhouse buss compressor: Amazing on drums, even on master bus. Tight and deep but still natural. Just slap it in there and it makes stuff sound better.
SPL Passeq: I’ve been using this on kind of arranging tool, making drones and arps and other noises fit together on the frequency spectrum. Big tone shaping potential and even drastic changes sound natural.
