Do you guys use it on buses or single tracks too? When are you doing this? And how?
Whenever you consider adding an effect to a track, to a group, or to the mix bus, you should always ask: "What am I trying to accomplish, and will this plugin help with that?"
The effects you use in a mix and the moves you make, are entirely dependent on the musical arrangement, the sounds and instruments, the mood or intent of the track, and your overall goals for the mix. Whenever you use a plugin, you need to have a good reason for adding it to your mix.
There is no one-size-fits-all answer in mixing.
Let's say you have a synth bass track. Don't just automatically add compression, or a "recommended" EQ preset, or an automated plugin like Teote. Listen first to the bass part within the context of the mix, and ask yourself if it's missing something, does it sound uneven, does it have too much energy in a certain frequency range, is it competing with other instruments, etc...
If you detect problems with it, then take the necessary steps to correct them. EQ can be used to tame or boost selected frequencies, compression can be used to even out the sound, collisions with other instruments can be addressed by modifying the arrangement, etc. Most mixing problems can usually be solved just with EQ and/or compression. Nothing more is necessary.
Also, listen to each track in isolation to identify problem frequencies in the source. A lot of sample libraries, especially strings and brass, have built-in artifacts and anomalies that need to be addressed with surgical EQ cuts. Listen for harsh frequencies or heavy buildup in the low-mids and gently notch these. An automated plugin cannot do this for you adequately - not even Soothe or Gulfoss. You need to use your ears.
As I've mentioned in previous posts, I like to use Teote on the mix bus, but only to make very minor corrections. If I see it working hard to modify the EQ curve, I'll go back to the mix and make the necessary changes to individual tracks and groups. In this way, Teote acts more like a "mix checker" for me, rather than a "mix fixer".
Ultimately, you should try to use as few plugins as possible when mixing. Nearly everything you need to achieve a good mix can be acomplished with your DAW's stock EQ and compression plugins. People were creating stellar mixes long before plugins like Teote, Gullfoss, Soothe, God Particle, etc. were available.
Based on some of the questions you've been asking, I would recommend taking a mixing course on Groove3 or Udemy, or watch some
reputable mixing tutorials on YouTube. This will help you far more in the long run than throwing more plugins at your mixes. Trust me - I went down this path myself years ago - I used to think fancy plugins were the way to get great mixes. They're not. All I needed was to get some basic knowledge of mixing techniques and to develop and trust my ears.
Good luck and have fun!!
