Musiqual Blue MKII is a Class A-style channel strip plugin with a 16-band EQ, harmonic distortion, and compression, designed to add warm, analog character to audio.

Purpose and Character
Musiqual Blue MKII is designed to emulate the warm, fat, and smooth sound of Class A audio gear. It combines three core components—a 16-band EQ, harmonic distortion, and a compressor—into a single plugin. The EQ provides 16 carefully selected frequency bands, each with a dedicated “Color” algorithm, allowing for musical equalization that imparts a Class A flavor.
The harmonic distortion section recreates asymmetrical clipping typical of Class A circuits, giving users control over the amount of overdrive. Additionally, the unit tends to bring sounds forward in the mix, enhancing perceived depth of field. This makes it suitable for adding analog-style coloration and presence to individual tracks or buses.
Key Capabilities
The EQ’s 16 bands cover key frequencies associated with Class A gear, offering flexibility for tone shaping. Each band’s Color algorithm enhances the unit’s character, going beyond a standard EQ to provide a more musical response. The distortion component is designed to mimic the sound of an overdriven Class A circuit, with user-adjustable intensity.
The compressor is specifically tuned to complement the Class A character, with fixed attack and release settings. This simplifies operation—users only control the amount of compression applied. Together, these components allow for precise control over coloration, harmonic distortion, and compression, making it a versatile tool for adding analog warmth.
Workflow and Integration
Musiqual Blue MKII is part of the Musiqual Series, which also includes Red (Tube) and Green (Transistor) versions. Each plugin combines a single-band EQ, harmonic distortion, and compressor in a straightforward layout. The fixed attack and release on the compressor streamline mixing, letting users focus on the amount of compression rather than complex timing settings.
The plugin supports Mac OS X 10.7 Lion and above (64-bit) and Windows 7/8/10 (64-bit). It requires a free iLok account and iLok License Manager, with licensing via USB or iLok Cloud. Plug-in formats include AAX Native (64-bit), Audio Units, and VST3, making it compatible with most major DAWs.
Practical Applications
In practice, Musiqual Blue MKII can be used on individual tracks to add warmth and presence, such as vocals or guitars, where its forward-sounding EQ helps instruments sit better in a mix. The distortion is ideal for adding subtle grit to bass lines or drums, while the compressor can glue elements together without complex sidechain routing.
For bus processing, the plugin can impart a cohesive analog character across a stereo group. Its design suits genres like rock, pop, or any style where classic analog warmth is desired. Users can blend the three components to taste, from gentle coloration to more aggressive overdrive, making it a flexible mixing tool.
