A Natural Analog Workflow
LUNA is based on a powerful hardware-software integration, giving Apollo interface owners the fastest, most natural recording system for music creation, editing, and mixing on your Mac. No more toggling between Apollo's Console app and your DAW to track through UAD plug-ins in real time, or messing with buffer settings.
Instead, LUNA's Accelerated Realtime Monitoring™ lets you record through UAD plug-ins with no discernible latency, and eliminates hassles in creating monitor mixes, cue mixes, setting up Unison plug-ins, and so much more.
LUNA is integrated directly with Universal Audio interface hardware. You must have a Thunderbolt-equipped Apollo connected and powered on to start LUNA. Tight integration with UA hardware means that much of the complexity of audio interface configuration is removed with LUNA. All of your available hardware inputs and outputs are automatically configured and available in LUNA. In addition, all preamp channel features and Unison inserts are automatically available in LUNA, and most routing features of the hardware, including Cues and routing matrix features, are available.
Accelerated Realtime Monitoring
Accelerated Realtime Monitoring™ (ARM) is a deep hardware, DSP, and software integration feature inside LUNA that allows you to achieve the lowest possible latency while recording with UAD plug-ins in real time.
For those familiar with UA’s Console software, ARM eliminates the need to use the Apollo Console app altogether, while providing all of the same features and benefits (low latency plug-ins, input routing, cue mixing, and others). Unlike Console, LUNA and ARM automatically take care of the muting and unmuting of input channels, based on the transport state of the software: Apollo channels that are record-enabled or input-enabled are unmuted, and all other Apollo channels are muted.
For a detailed description of Accelerated Realtime Monitoring, see Accelerated Realtime Monitoring.
Accelerated Realtime Monitoring™ (ARM) eliminates the need to use the Apollo Console app to track and input monitor through UAD plug-ins at the lowest possible latency. Accelerated Realtime Monitoring offers you the ability to effortlessly achieve the lowest possible latency while recording with Apollo. Accelerated Realtime Monitoring seamlessly handles channel input states, allowing for the use of UAD plug-ins on channel inserts for Realtime UAD Processing, without having to leave the LUNA workspace. ARM offers UAD plug-in processing at undetectable latencies while monitoring and/or recording multiple inputs and tracks.
LUNA takes care of the muting of input channels, based on what is in use in the session. Apollo channels that are record-enabled have their inputs unmuted, and all other channels have their inputs muted. Apollo integration automatically controls the muting of inputs and recorded material on disk according to the record enable or input enable and transport state.
You can turn Accelerated Realtime Monitoring on or off globally. Use this setting to achieve the lowest possible input monitoring latency when monitoring input signals through monitor, headphone, and cue outputs.
LUNA’s recording engine is fast and highly capable. LUNA records 24-bit audio at the current hardware sample rate, on as many tracks as your computer can support. With LUNA, you can switch the transport in and out of Record while playing audio. You can also enable and disable recording on tracks while the transport is running, so you can punch in manually on one or more tracks while playing back a session. All audio and MIDI recordings are delay-compensated on playback, so everything stays tightly synced.
Previously, with the Console App, you had to choose whether or not to record insert effects on input channels. In LUNA, as with the Console App, Unison insert processing is always recorded to disk. However, unlike the Console App, each input channel has four available Record FX slots in addition to eight standard inserts (used for any combination of Audio Units or UAD plug-ins). These inserts allow you to record through up to four UAD plug-ins on any available input channel (depending on available UAD DSP resources). In addition, UAD and non-UAD plug-ins can be assigned to standard Inserts (not recorded to disk) for monitoring while you record, without being recorded to disk.
Notes on plug-in processing:
- Only UAD plug-ins can be assigned to a record-enabled track when Accelerated Realtime Monitoring is enabled. When you enable ARM, any AU plug-ins on a record or input-enabled track are disabled.
- When a track is record or input-enabled in ARM mode, the last four standard inserts are disabled.
LUNA and Console
You never need to use Apollo’s Console app when you are using LUNA. LUNA replaces almost all functions for which you previously used Console. LUNA also includes a number of features that Console does not.
For example, a LUNA session includes persistent Inputs. When you configure a LUNA track with an input, all settings, including Unison plug-ins, Record FX plug-ins, and Insert effect plug-ins, are retained on that track. You can reuse the same input on your Apollo on multiple tracks, and each track in the session will continue to retain the settings that were last used for it, even after you close and reopen the session.
If you prefer to use Console, the settings you configure in Console are removed when LUNA starts, and restored after you quit LUNA. Note that the Isolate and Flex Routing features are configured in Console.
Console Isolate feature
Isolate retains current channel settings when different Console and LUNA sessions are loaded. Isolated channels are also not controlled by LUNA. Isolate allows you to seamlessly monitor live hardware inputs with Realtime UAD Processing, even when changing Console and LUNA sessions. You can use this to prevent a Console channel’s state from changing across LUNA sessions. When a channel or channel pair is Isolated the plug-ins on that channel cannot be changed in LUNA, and the channel input pair is not automatically muted and unmuted by the LUNA mixer—the channel or channel pair is always live.
The only exception to this is that an Isolated input or input pair is muted when a track that uses that input is Record-enabled and LUNA is playing back audio from that track.
Console Tracking Mode
Console Tracking mode allows you to use Console for live channel inputs, and prevents LUNA from automatically muting and unmuting Console channels when recording. Essentially, all inputs remain live, and Console works as it previously did, while LUNA is running.
In Console Tracking Mode, UAD plug‑ins do not persist in LUNA inputs as they normally do. Instead, when you record-enable a track in Console Tracking mode, the plug-ins assigned to the track in Console are loaded into the LUNA channel. However, unlike with Isolated Console channels, in Console Tracking Mode, you can change the plug-ins assigned to the track in LUNA, and those changes will carry over to Console. Console channels then return to their previous states after you quit LUNA.
Note: A Console input is muted when ARM is enabled, a track that uses that input is Record-enabled, and LUNA is playing back audio from that track.

When you record audio in LUNA, that audio is stored in the session file. You can edit the audio by copying, cutting, trimming, and deleting sections, while not actually deleting the underlying audio file. Similarly, when you record multiple takes of audio with loop recording, or you record audio over an existing audio file or file section, the previous audio files are retained. You can access all whole audio files recorded with loop recording from the Track Versions feature.
How do I Save?
With LUNA, all changes are saved automatically. LUNA writes changes to a database file that is embedded within the LUNA session file. This database is updated with every change and keeps a constant record of your LUNA session. There is no traditional Save function in LUNA, as all edits and modifications are automatically saved, and all audio is embedded in the LUNA session file. You can undo and redo changes (except when recording) even after closing and reopening a session. You can also save a copy of a session.
LUNA automatically autosaves versions to which you can revert, based on the Autosave Interval in LUNA settings.
Undo and Redo
You can undo and redo changes in an open session at any time, except during recording. You can even undo and redo changes after a session has been closed and reopened.
Supported Plug-In Formats
LUNA supports UAD Powered Plug-Ins, LUNA Extensions, LUNA Instruments, and Audio Units (AU) plug-ins. LUNA Extensions include Tape Machines and Neve Summing. Extensions are incorporated into the LUNA workflow. Instruments appear in a separate plug-ins list from insert effect plug-ins.
Track Follows Modes: Time and Tempo
Audio tracks can be in one of two Track Follows Modes: Time or Tempo.
A track in Track Follows Time mode maintains its original playback time, regardless of changes in the tempo of the session. All audio clips on the track, and elements associated with those clips, maintain their original time duration, including start and end points, edits, fades, and automation.
A track in Track Follows Tempo mode adjusts to the tempo of the session and any session tempo changes. An audio clip that is configured in Track Follows Tempo mode will automatically become shorter or longer if the session tempo is adjusted. All audio clips on the track, and elements associated with those clips, scale to the new tempo. Clip start and end points, duration, edits, fades, and automation all scale to the new tempo.
Sample Rates, Imported Audio, and Imported Sessions
LUNA sessions are not locked to a specific sample rate. You can change the sample rate of a LUNA session after you create or import it, without changing the sound or playback speed of the session.
LUNA always records audio as 24-bit files at the current hardware sample rate. All internal files, exports, and mix operations employ a 32-bit floating point architecture. You can import audio of any sample rate, or play back an audio session at any supported hardware sample rate, and LUNA intelligently renders and manages the audio to play it back correctly. Audio that you import into LUNA is saved in the session file with the same bit depth and sample rate at which it was imported.
Focus Browsers Overview
In LUNA, many operations open a Focus Browser at the left of the screen. For example, when you click the Preset button on a plug-in, a list of available presets appears at the left side of the screen. This methodology is much more conducive to fast workflows instead of burying functions within menus and submenus.
With a Focus Browser, you typically make a choice. For example, you choose an input to use for a track, or a preset to use with a plug-in.
Track Focus Browser
Workflows provide common editing, arranging, and navigation commands on a toolbar that you can open under the main LUNA control bar.
