I've recently gotten to know the Puff a bit better on a project that was live recorded ~ok~. Afro funk/punk is how I'll classify it. Drums, Bass, 2 guitars, 2 sax, 1 trumpet, one vocal. An all at once recording in a good space with minimal separation. The drums overhead felt quite distant, and the trumpet mic seemed to have picked up the player's lack of confidence; no matter how quiet or loud he was, he always sounded buried.
BUT! Put a Puff on the trumpet, and another on the horns bus, brought him and the other horns up to a presence that was more consistent without getting smashed with compression.
Same with the overheads. Depending on the song I put a puff on it, or the drum bus. It acted similar (but better! in this case) to DynOne adding parallel MB compression.
Still need to get to know it better, I was tempted to sprinkle some puff around on the other sources but played it conservative.
Adding a DoublePuff (or two on the mix bus) feature would be highly interesting to me. This project is out for approval so I'm hesitant to try it out right now.
