Ableton/Live/UG/29 Audio Effect Reference/13 Dynamic Tube

- Dynamic Tube adds tube saturation, with an envelope follower that varies the tone with input level.
- Tube models:
- A — clean at low Bias, adding bright harmonics once the input passes a threshold
- B — between A and C
- C — a poor tube that always distorts
- Tone — moves the distortion toward the highs or down through the mids and lows
- Drive — how much signal reaches the tube; more is dirtier
- Bias — tube intensity; very high values make the signal break up
- Envelope — lets input level move the Bias. Positive values make loud parts dirtier; negative values clean them up, an expansion effect.
- Attack and Release — envelope response; no effect when Envelope is 0
- Output — final level
- Hi-Quality in the title bar's context menu reduces aliasing, especially on high frequencies, for slightly more CPU.
