Warming up keys and adding weight to bass with opto compression

MusicTechHelpGuy applies quick bus treatments to keys and bass inside Logic Pro's Track Stacks workflow. On the keys bus, he reapplies ChromaGlow saturation for the same warmth and cohesion used earlier on vocals.

For bass, he reaches for the Vintage Opto compressor to fatten up the low end. It's a fast, minimal move rather than a detailed walkthrough, useful as a reminder that gentle opto-style compression can add weight to a bass group without heavy-handed processing.
