Designed by Experts, Built on Legacy
Softube has a lengthy history of emulating professional audio gear. After close to two decades working in collaboration with premium brands like Weiss Engineering, Tube-Tech, Solid State Logic, Chandler Limited®, and Trident, we have a reliable track record of recreating classics in software form that sound exactly like their hardware counterparts.

Weiss MM-1 Mastering Maximizer is built on this legacy. We took the same meticulous approach we always do, and then we took it further. The DS1-MK3 algorithms that grace MM-1 are not merely stunning recreations. They are the algorithms themselves. We undertook the daunting, yet rewarding, task of code porting each line of the original DS1-MK3 code used in MM-1. The result is the stunningly transparent sound quality of Weiss Engineering. Nothing less.

Styles to spare
Reach max mastering sound with minimal tweaking. Select any one of MM-1’s five limiting styles from Transparent to Deess and then use the amount knob to dial in the proportion of processing defined by that style. With Transparent, you can retain as much of the original transients and dynamics as possible while focusing on adding subtle compression that leaves room to bring up RMS. The Loud setting lets you focus on maintaining headroom for the limiter to reach for a higher RMS. Punch adds weight and brings out transient material for an energetic-feeling mix. Wide allows you to create a three-dimensional sound by widening the drums, backing instruments, or the entire mix. And, to smooth out frequencies that could otherwise be harsh, simply deploy Deess.

The Weiss amount
The name Weiss resounds in the pro audio mastering sphere. And, since its launch in the 1990s, Weiss DS1-MK3 has become the exemplary mastering unit. Despite its premium price tag, it is indispensable to professional mastering studios around the world. Its unrivaled transparency, unparalleled versatility, and exceptional sound quality have gained it a place on almost every major album of the last twenty-five years. Softube + Weiss MM-1 Mastering Maximizer features the exact compression, limiting, and deessing algorithms of DS1-MK3. With the Parallel Mix knob, you can apply the perfect amount of the coveted Weiss sound to your original mix. And our line-by-line code porting process means that what you hear is always authentically Weiss.

Side effects
Secure your mix's spot on any and every stage with MM-1 Mastering Maximizer. With MM-1's side menu you can instantly and effortlessly select common dBFS standards ensuring that your mix is presented with the proper headroom for a variety of formats. Use the side menu to make rapid adjustments to the output dBFS from zero to -1.0 and guarantee that your limiting delivers a finished product that's compatible with YouTube, Spotify, physical spaces, and every platform in between.

Console 1 Ready

Clear-cut quality
Since its release in 1996, Weiss DS1-MK3 has garnered the affection of professional mastering engineers the world over. The TEC Award-winning mastering processor is the white box seen in every top studio and the coveted crystal-clear sound heard on every major album of the past twenty-five years. With stunning transparency, unmatched flexibility, and outstanding sound quality, DS1-MK3 is the mastering unit that all others are measured against. Softube's DS1-MK3 and MM-1 Mastering Maximizer are the only plug-ins created in collaboration with and officially endorsed by Grammy-winner Daniel Weiss and Weiss Engineering. It’s a difference you can hear with Weiss-clarity.

Sonic odyssey
Weiss Engineering has been a pioneer in digital audio equipment design since 1979. It was then that founder Daniel Weiss joined Willi Studer AG in Switzerland. In 1985, when Weiss struck out on his own and founded Weiss Engineering, he focused on developing digital audio equipment for mastering studios. The result of that endeavor is now legend.

The tale of Softube and Weiss Engineering dates to 2008 but, if the subsequent suite of products is any indication, it’s already an epic. Despite having so many guiding principles in common with Weiss, we didn’t get serious about working together until 2015. After three years—and a whole lot of blood, sweat, and tears—the Softube + Weiss DS1-MK3 plug-in was released to great acclaim. Now, the saga continues with Weiss MM-1 Mastering Maximizer.
