Audio developers Temecula DSP have officially launched MDV-II, a free virtual effects processor for macOS and Windows. The plugin is a meticulous recreation of the Alesis MidiVerb II, the 1987 rack-mount unit that defined the sound of shoegaze, dream pop, and 80s electronic music.
Recreating a Cult Classic: The DASP-16 Engine
At the core of the original hardware was the custom DASP-16 (Digital Audio Signal Processor) chip, designed by the legendary Keith Barr. Unlike modern “clean” reverbs, the MDV-II focuses on character and grit.
Temecula DSP has successfully modeled this chip to reproduce the signal flow of all 100 factory programs. To ensure total authenticity, the plugin operates at the original 31,250 Hz internal sample rate, capturing the “bandwidth-limited charm” and warmth that made the hardware a studio staple.
Double the Power: The Dual-Unit Advantage
While the original hardware allowed for only one preset at a time, the MDV-II introduces a modern workflow enhancement:
-
Serialized Dual-Engine: The plugin features two mathematically modeled DASP-16 chips (Unit A and Unit B) running in series.
-
Creative Stacking: Producers can now chain iconic effects, such as feeding a reverse reverb into a chorus or a gated reverb into a delay.
-
Independent Control: Each unit features its own program selection, mix, and bypass controls for precise sound shaping.
The “Secret Weapon” of Shoegaze
The MidiVerb II has long been associated with high-profile artists seeking “lush nostalgic washes.” Kevin Shields of My Bloody Valentine famously cited the unit’s reverse reverb program as a “secret weapon” for his signature guitar sound.
“There are two types of producers: those who think this reverb sounds ‘too colored,’ and those who refuse to mix a track without it… We recreated this cult-classic unit because sometimes, perfection is boring.”
