Waves releases Kramer MPX Master Tape Plugin

Developed in association with Eddie Kramer, the MPX Master Tape plugin is modeled on a rare machine consisting of an Ampex 350 transport and 351 electronics. With adjustable tape speed, bias, flux, wow & flutter, and noise parameters, the MPX provides comprehensive control over the contours of your sound. And to top it off, we’ve added a flexible slap & feedback delay, ideal for rock, dance, dub, you name it. For recording, mixing, mastering, and more, bring the richness and warmth of real tape saturation to your DAW with the MPX Master Tape. It’s the reel deal.

The MPX Dream Team
Special thanks go out to Eric Schilling (Shakira, Gloria Estefan, Natalie Cole, Elton John) who provided us with the machine, Bob Olhsson (Stevie Wonder, Marvin Gaye, Diana Ross) and especially John Haeny (Bonnie Raitt, Weather Report, Jackson Browne, Linda Ronstadt, Jim Morrison, Tom Jones), who provided invaluable assistance in the development of the MPX plugin.
