It was the last instrument that Robert Moog participated in the design of and was released by the company shortly after Robert's death in 2005. With the release of the Sub Phatty in 2013, Moog Music introduced the first synthesizer with an entirely new circuitry schematic since Robert Moog's death in 2005. This new synthesizer featured a new oscillator design with an updated analog sound an increased panel dive edit-ability. This popularity of this instrument inspired multiple subsequent versions from the company with the release of the Sub 37 and Subsequent 37. These synthesizers introduced additional features such as a sequencer and brought edit-ability up from the dive format to the immediate accessibility of the front panel. Embracing renewed interest in modular synthesis and the ever growing Eurorack synthesizer standard's popularity, Moog Music introduced the Mother-32 as a Eurorack compatible synthesizer featuring Moog circuitry and sound. They have since released a number of modules as well as modular and semi-modular synthesizers. Following in the footsteps of the early modular synthesizer reissues the company introduced in the 2010s and the Mother-32 and other Eurorack friendly options of the same decade, Moog Music introduced the semi-modular Moog Grandmother synthesizer, offering buyers of Moog instruments the freedom of modular patchability combined with the immediate accessibility of a fixed path synthesizer. The synthesizer again yielded an expanded version released by the company named the Moog Matriarch in 2019. Moogfest is the name of a festival started in 2004 in New York City that was founded to honor the work of Robert Moog, better known to the electronic music community as Bob Moog, as well as electronic music and, eventually, technology and development. It eventually moved to Asheville, NC in 2010 and ended its affiliation with AC Entertainment in 2012. The festival, which, after its first relocation, brought a boom to Moog Music Inc.'s corporate home in downtown Asheville in part thanks to the festival's sizable attendance, eventually relocated to Durham, NC due to an increased desire to bolster the tech and development arms of the festival, taking into consideration Durham's status as an up and coming tech center. The festival has attracted high profile acts such as Keith Emerson, Laurie Anderson, Brian Eno, and Jónsi of Sigur Rós as well as numerous emerging and experimental groups and artists. Additionally, the festival features workshops and presentations that focus on instrument development and building (for instance the Moog Werkstatt-Ø1 was initially offered as a festival-build activity), music tech, and research.
