The Rackmode Signal Processors Black Friday deal takes 50% off Cherry Audio's effects bundle, bringing it to $49 until Nov 27, 2026.
Rackmode is a collection of seven virtual effects plus an instrument plugin, built to replicate the rack-mounted Moog Signal Processors of the 1970s and '80s. Cherry Audio says this is the first time the whole line has been recreated as plugins.
Synth designer and DSP developer Mark Barton (MRB) modelled the circuits, working from the original rack hardware.
The vocoder comes in two forms. The instrument version has a built-in dual oscillator, and the FX version processes other inputs and DAW tracks. Both need a DAW that can sidechain.
The Phaser is based on the 12 stage original. The Ring Modulator follows Harald Bode's design and adds a Squelch control.
The String Filter comes from a rare unit built by Moog's Custom Engineering Group. It uses filter arrays that mimic acoustic string instruments.
The Frequency Shifter either mixes two external inputs or sidechains a single input against its own oscillator. It works by changing the ratio of the incoming frequency components, which the maker says gives colourful, often metallic results.
The Graphic EQ has ten selectable bands with Drive and Gain controls. The Parametric EQ has three bands covering low, mid and high ranges.
The maker has extended the hardware's feature set for current workflows:
Cherry Audio also says the code is highly optimised for ultra-low CPU load. The plugins mirror the look of the original rack enclosures too.
On Mac, you get AU, VST, VST3, AAX and Standalone. Mac OS 10.13 or above is required, 64-bit only, and macOS 13 Ventura is supported. Native Apple Silicon M1 support is included, M1 Ultra among them. The maker recommends a 3.4 GHz quad-core or M1 CPU with 8GB of RAM.
On Windows, you get VST, VST3, AAX and Standalone. Windows 7 or above is supported, including Windows 11, 64-bit only. A quad-core machine with 8GB of RAM is recommended.
An internet connection is needed for product activation.
Moog Music, then owned by Norlin Music, launched the Signal Processor family to reach further into the production studio. It included the 16 Channel Vocoder, the 12 Stage Phaser, and the Ten Band Graphic and Three Band Parametric Equalizers.
The Frequency Shifter and Ring Modulator were related rack units, both designed by Harald Bode. The maker lists Wendy Carlos, Tangerine Dream, John Carpenter, Genesis and Coldplay among the artists who used the hardware.
Moog is a registered trademark of Moog Music, Inc. Cherry Audio and its products have no association with Moog Music.
