Reason Re Ladder Multimode Filter [win] -
: Includes a unique stereo-spacing effect, allowing users to spread the filter across the stereo field, which is not possible on the original mono hardware.
: It is frequently cited as a "CPU hog" compared to other filters. Users on ReasonTalk note that while it sounds excellent, it consumes significantly more DSP power than standard filter REs due to its complex component-level modeling. Reason RE Ladder Multimode Filter [WiN]
: Uses advanced DSP based on industrial circuit simulators to replicate the specific non-linearities and saturation of the original Moog hardware. : Includes a unique stereo-spacing effect, allowing users
: Unlike the original hardware, which was primarily low-pass, this RE features a mixer that allows for simultaneous low-pass (LP), band-pass (BP), and high-pass (HP) filtering. : Uses advanced DSP based on industrial circuit
The Rack Extension (RE) for Reason, developed by Primal Audio , is a high-fidelity analog-modeled filter based on the legendary transistor ladder design of the Minimoog . It is widely regarded for its "warm" and "organic" character but is also known for being resource-intensive. Core Features
