Pulsar Modular builds analogue-modelled processors with an obsessive focus on sound over feature lists. The P22 Rail clipper, stocked at VST Vault, comes from the mastering side of the range, where the brand earned a following among engineers who compare its output stages favourably to hardware. Expect minimal interfaces, careful gain staging and processing designed to be pushed hard without falling apart — these are tools for people who listen more than they look. Plugins run on Mac and Windows in VST3, AU and AAX formats, loading in Pro Tools, Cubase, Studio One, Logic Pro and the other major DAWs, with both platforms delivered instantly in one purchase.
