Undertone Audio have just launched a new plug-in that brings one of their most popular hardware designs into software for the first time. MPEQ-1 is said to capture the sound and flexibility of the physical MPEQ-1, while adding some creative tools that extend its capabilities beyond what was possible in the hardware version.
Designed for mixing and mastering applications, the new MPEQ-1 plug-in introduces independent saturation controls on every EQ band, allowing users to shape both the frequency balance and harmonic character of their source material. The EQ bands can be controlled directly using familiar digital parameter controls, or via a graphic recreation of the hardware.
As the plug-in has been created by the same team that were behind the original unit, MPEQ-1 meticulously recreates the iconic hardware’s curves, versatile filters, wide-range Q control and unique Vari-Phase mode across its four super-parametric bands. It also introduces the obvious benefits of a plug-in, including full setting recall and automation, as well as offering instant built-in A/B comparisons and onboard spectrum analysis.
“Engineers have been asking us when we would release a plug-in version of the MPEQ-1 and our answer was always: only when we could do something genuinely new. The MPEQ-1 has always been about expanding what an equaliser can do. By combining the EQ’s flexible architecture with independent saturation, the plug-in gives engineers and producers a level of tonal control that simply wasn't possible before.” - Eric Valentine, Founder, Undertone Audio

MPEQ-1 is supported on PCs running Windows 7 or above, and Macs running macOS 10.13 and higher. VST3, AU and AAX plug-in versions are available.
