Desktop 12 x 18 Thunderbolt 3 Audio Interface with Realtime UAD-2 QUAD Core.
Apollo x4 allows musicians and producers to easily track, overdub, and mix larger projects with elite-class A/D and D/A conversion, four Unison-enabled preamps, and QUAD Core realtime UAD plug-in processing — all in a desktop Thunderbolt 3 audio interface for Mac or PC. Built upon UA’s 60-year heritage of audio craftsmanship, Apollo x4 confidently outperforms everything in its class, with 127 dB D/A dynamic range and an included bundle of UAD analog emulation plug-ins, giving you a fully-stocked analog studio, right on your desktop.
LUNA Recording System for Mac
Included as a free download with all UA Thunderbolt audio interfaces, the LUNA Recording System is designed to give Apollo owners the most natural, inspiring and analog-sounding music production environment available for Mac. This digital system integrates directly with the hardware to deliver analog sound and creative immediacy. It uses real-time processes more commonly associated with analog recording, versus typical digital audio workstation (DAW) workflows.
Deep Integration With the Apollo Interface
In addition to its seamless hardware-software integration with Apollo and Arrow, the LUNA Recording System allows capturing audio through DSP-powered UAD plug-ins with no discernible latency. The system also includes Accelerated Realtime Monitoring, which provides fast analog-style tracking and overdubbing workflows using Apollo’s onboard DSP acceleration. LUNA's deep Apollo integration will be a revelation for anyone who has not recorded music on a highly expensive, DSP-assisted recording system. LUNA makes music production feel more robust, dependable and intuitive, without latency and monitoring hassles.
Extensions Built Directly Into the Software
The LUNA system works with a variety of exclusive LUNA extensions, including two that come free with download. These are not plug-ins that require multiple instances and windows—they are controlled from within the app. The Oxide LUNA extension comes free with download and features multitrack tape emulation, bringing the warmth and punch of tape to any audio or instrument track. For those who want to delve deeper into magnetic tape sounds, there is the Studer A800 multichannel tape recorder extension (sold separately). Other available options include the Neve Summing extension, which recreates the audio summing circuitry of the Neve 80-Series audio mixing consoles designed by Neve Electronics in the 1960s and early 70s.
LUNA Virtual Instruments
LUNA also features the first-ever virtual instruments from Universal Audio. Using their expertise in electrical and acoustic modeling, sampling, synthesis
and signal processing, UA was able to make their LUNA instruments realistic, responsive and "alive." Free with download, LUNA includes the Shape creative toolkit with modern and vintage keys, drums/percussion, guitar/bass, orchestral content and real-time synthesis, courtesy of Universal Audio, Spitfire Audio, Orange Tree Samples, Loops de la Creme and more. Sold separately are premium instruments including the Moog Minimoog synthesizer and the Ravel grand piano, which is based on UA-exclusive samples of a Steinway Model B.
Other features include auto-saving, UAD and AU compatibility, auto-saving and AAF session imports from other DAWs. The LUNA system is free to all owners of Thunderbolt-equipped Universal Audio interfaces including Apollo and Arrow. It requires a modern Mac running macOS Mojave or later.
