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
: 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. Reason RE Ladder Multimode Filter [WiN]
: 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. The Rack Extension (RE) for Reason, developed by
: It can be used for subtle harmonic thickening or driven into heavy analog distortion and "mayhem". Performance & Sound Analysis : Unlike the original hardware, which was primarily
: Users describe the sound as "utterly fantastic" and very faithful to the iconic "Moog sound". The resonance adds a distinctive overdriven warmth that is a hallmark of the 24dB/octave ladder architecture.
: Uses advanced DSP based on industrial circuit simulators to replicate the specific non-linearities and saturation of the original Moog hardware.
