Rather than drip-feed its new range of effects, famed freeware plugin developer B. Serrano has chosen to make the whole lot available in one go.
IO is a bundle that features five effects: Paraphonic multifilter; Stereo phaser; Multi level adjuster; Multi level auto-pan; and Ring Modulator.
The common thread running through all the processors is what B. Serrano describes as a "sophisticated GUI envelope". This can run from a single nanosecond to several minutes - or even hours if you want it to.
IO is available for Windows systems now from the B. Serrano website.
