B.Serrano has released IO, a free collection of VST effects for Windows.
- A paraphonic multi-mode Filter.
- A Phaser.
- A Volume modifier.
- An Auto-Pan.
- A Ring-Modulator.
These effects are driven by a sophisticated GUI envelope. Default time value is in seconds. Duration is theoretically infinite so this envelope can run from 1 nanosecond to several minutes or hours.
