Free Reverb For Mac, Windows Recreates Vintage Alesis MidiVerb II Sound

Temecula DSP has introduced MDV-II, a free virtual effects unit, for macOS & Windows, inspired by the Alesis MIDIVerb II.

The heart of the MidiVerb II is the custom DASP-16 (Digital Audio Signal Processor) chip designed by Keith Barr. The MDV-II faithfully recreates this chip, reproducing the signal flow of all 100 factory programs at the original 31,250 Hz internal sample rate. Every program produces the same output as the original hardware — including its characteristic warmth and bandwidth-limited charm.

The MDV-II goes beyond the original hardware, though, with two mathematically-modeled DASP-16 chips running in series. Unit A feeds into Unit B, so you can stack a reverse reverb into a chorus, run a gated verb into a delay, or chain any two of the 100 programs together. Each unit has independent program selection, mix, and bypass controls.

Here’s what they have to say about it:

“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 meticulously recreated this cult-classic unit because sometimes, perfection is boring. You use it when you want your synth to float in space, your guitars to smear into a lush nostalgic wash, and your mix to have a sound that’s unmistakably its own.”

Temecula DSP MDV-II is available now as a free download.

  1. Great plugin. It was one of my favourites as hardware based processor not because it soured so good but because it sounded so different 😉
    Insta download for me 🙂

  2. MidiVerbs and Boss pedals were my reverbs for a long time. They always delivered, so I’m happy to see the low sampling rate retained here. Using a low-res reverb on a synth to enhance a more capable, modern one is often a good textural option. Think of it as a specialty module.

    1. Without any mention of this open source project on the Temecula website or project documentation, how can you be sure that the MDV-II uses this specific code? The repository you linked to is only three months old, so I’m skeptical of your claim.

      There have been quite a few Midiverb emulations over the years and the underlying tech is like 30 or 40 years old now, there’s nothing really new here. The repository you linked even mentions that the code is based on someone else’s code, which itself is based on the Alesis product. This is emulation of emulation of emulation.

      Be happy for a free plugin and make some music.
