Introduction

Put the Sound of a Symphony on Your Desktop

Symphony Desktop for Mac, iPad Pro and Windows offers the legendary sound quality of Apogee’s flagship Symphony I/O Mk II into an elegant 10x10 audio interface that sits on your desk and fits in your bag. With Symphony Desktop, musicians and producers are empowered to record, overdub and mix with the music industry’s most respected AD/DA converters and mic preamps.

By combining superior performance with new features like mic preamp emulation, the Symphony ECS Channel Strip and Clearmountain’s Spaces reverb plugins, and ultra low latency recording with hardware DSP and Apogee native FX plugins, Symphony Desktop will amplify your creativity in the studio or on the go, giving your recordings the Apogee quality advantage.

Features

With everything at your fingertips, your music creation and production flows freely, whether you’re on a Mac, Windows or iOS platform.

Apogee Symphony Desktop User’s Guide

Apogee Alloy Mic Preamp Emulation

Apogee Alloy mic preamp emulation offers analog circuitry plus DSP processing to create the richest, most authentic audio modeling available in an audio interface. Critical aspects of the model such as input impedance, transient profile and distortion characteristics are first implemented in the analog domain, followed by precise and accurate refinement in DSP, for a hybrid result that’s greater than the sum of its parts.

The AP-66 emulation is based on the Class A solid-state Neve 1066 mic preamp, with a characteristic low-mid color and slightly compressed transients.

The AP-57 emulation offers the lush, larger-than-life tube saturation of a carefully restored 50s era Ampex 601 preamp.

Innovative Workflows with Hardware DSP

Symphony Desktop includes flexible and powerful onboard hardware DSP processing that supports a wide range of innovative workflows, using the Apogee Channel FX plugin. Whether you’re printing your tracks with Apogee Alloy mic preamp emulation or enjoying the benefits of DualPath monitoring, there’s a DSP-powered workflow that fits you like a glove.

Apogee Plugins Included

Included with Symphony Desktop is the Symphony ECS Channel Strip plugin. Tuned by Bob Clearmountain, Symphony ECS includes EQ, Compression and Saturation for quick and effective processing when tracking vocals or acoustic instruments.

Also included is the Apogee Clearmountain’s Spaces plugin, which reproduces legendary mixer Bob Clearmountain’s personalized workflow for creating the distinctive, rich spaces where his mixes live. With the very same echo chamber profiles and processing he’s used on countless hit records, Clearmountain’s Spaces lets you envelope your tracks in unique and cohesive atmospheres that set your mixes apart.

Zero-Ohm Headphone Outputs

Symphony Desktop has two completely independent ultra low impedance headphone outputs that are individually routable, equipped with dual-sum ESS DACs. Output power range is tailored to the expected type of headphones: the front panel output can drive virtually any headphones, while the rear panel output is specifically designed for high-efficiency headphones.

Advanced Stepped Gain Mic Preamps

At the core of the input stage, Symphony Desktop’s mic preamps offer up to 75dB of gain. The preamp design features Apogee’s unique Advanced Stepped Gain Architecture to ensure ultra-low noise and distortion regardless of the source, from pounding kick drum to delicate fingerpicking on an acoustic guitar. With variable impedance settings on both mic and instrument inputs, Symphony Desktop optimizes the input stage to better match your specific devices, for deep lows and clear highs. Selectable mic preamp emulation adds character, attitude and a bit of grit to your recordings.

8. Channel Link Recall Preference - When a DAW Channel FX plugin is linked to hardware Channel

FX using the Channel Link setting, this preference determines which Monitor FX Settings are kept after linking. This includes the case when a DAW session with a previously linked Channel FX plugin is recalled.

● Always Ask - Display a dialog each time a Channel Link is established to determine which

Channel FX settings to keep - Monitor FX settings from the DAW or Monitor FX setting from the Apogee hardware.

● Keep DAW FX Settings - when a Channel Link is established, always keep DAW Monitor FX

settings. This is the default setting. In most cases, you’ll want to keep the Monitor FX setting saved in your DAW session.

● Keep Hardware FX Settings - when a Channel Link is established, always keep Apogee

hardware Monitor FX settings.

● Don’t ask again - when checked, this dialog is no longer displayed. It’s always possible to set

the preference back to Always Ask. If Symphony Desktop is reset, this preference is reset to Always Ask.

Note that the Print FX tab is never saved in the DAW session - it always displays the current

state of the hardware Print FX.

9. Recall 48v - This setting determines whether 48 volt phantom power is recalled with other Input settings like Input source and gain. Set to Off to avoid unintentionally applying 48 volt phantom power to Desktop’s XLR inputs. Set to On if you’re confident that no device connected to the XLR connectors will be harmed by 48 volt phantom power.

6. Load Print FX - Load and modify Apogee Channel FX plugins on the Print signal path. See

Apogee Channel FX Rack for more information about Print and Monitor FX.

Apogee Symphony Desktop User’s Guide

7. Analog Level - choose the analog reference level for Analog inputs 1-2.

● Choose Mic when connecting microphones or direct boxes to the XLR input.

● Choose Inst when connecting a guitar or keyboard, or any high impedance (Hi-Z) instrument

to the 1/4” input (balanced TRS or unbalanced TS).

● Choose +4dBu when connecting “pro” gear with a nominal +4 dBu output level (such as an

external mic pre, compressor, or EQ) to the XLR input.

● Choose -10dBV when connecting “semi-pro”, hi-fi, or musical instrument gear with a nominal

-10dBV dBu output level to the XLR input.

8. Preamp - Choose a Mic preamp

● SD-MP - Symphony mic pre with no emulation processing and a gain range of 0-75 dB.

● AP-66 - based on a vintage Neve 1066 mic preamp section with a gain range of 20-80 dB.

● AP-57 - based on a highly modified Ampex tube mic preamp with a gain range of 0-10.

9. Gain Control - Adjust the gain of the preamp. Gain Control is hidden when Analog Level is set to +4dBu or -10 dBV line input.

10. Input Settings - Provides options for the various inputs:

● 48V - Enable 48 volt phantom power on the corresponding Analog In channel. Visible only

when Analog Level is set to Mic. Most condenser mics require 48 volt phantom power to operate.

● Group - Link the Gain Controls (plus Output Level and Gain Link button when present) for

each Analog In channel. Visible only when Analog Level is set to Mic or Instrument. Gain offsets that exist before grouping channels are preserved.

● Soft Limit - engage Soft Limit on each analog input. Soft Limit is an analog circuit that begins

to attenuate transient peaks at a threshold of -4dBfs, replicating the transient softening of analog tape.

● Polarity Invert - Invert the polarity of the analog input signal. When a single sound source is

picked up with 2 transducers, inverting the polarity of one transducer results in a fuller sound. For example, if a drum is captured with a mic on each drumhead, inverting the polarity of one mic results in a fuller sound with more low end. The same principle applies when capturing an electric instrument with a miked amp and a direct injection feed.

Optical IN Channels

11. Optical IN channels represent digital inputs from external digital audio devices like standalone mic preamp expanders, digitally connected synths, and others.

● Optical inputs are routed to software (DAW) inputs 3-10, depending on the Optical Format

setting;

● Optical inputs are routed to direct monitoring Mixers 1 & 2;

● Optical inputs may be routed to Optical and Monitor outputs for Standalone operation.

Apogee Alloy Mic Preamp Emulation

Getting Started with the AP-66

The AP-66 is modeled after a vintage Neve 1066 with the “round-can” Marinair input transformer. Does this version of the input transformer sound “better” than the later rectangular version in the 1073? We’re not making any claims here, but we tried a few different modules (1066s, 1073s) and we chose this one to model.

When you first open the AP-66, the Input Gain and Output level are set so you’ll experience some saturation with many typical input sources. Raise the Input gain for more saturation, then adjust the Output level for a proper recording level.

Here’s a way to easily experience the entire range of our Neve emulation from subtle warming to full-on distortion while maintaining a relatively consistent output level:

1. Choose the AP-66 mic preamp emulation on the touch screen by tapping the IN1 button until the Settings view is displayed.

2. Tap Preamp, then choose AP-66, then tap the “X”.

3. Tap the IN1 button to display the Overview view.

4. Set Output Level to 0.

5. Input the signal to be recorded, and set Input Gain for a proper recording level. The meter should display an average level around -16 to -12 dBFs, with -6 dbFs peaks.

6. Tap GL (Gain Link) - now, as the Input Gain is raised, the Output Level lowers to compensate.

7. As you increase the Input Gain, you’ll hear more and more saturation, then an overdriven sound, and finally very audible distortion. Experience to discover the effect that best suits your creation!

Apogee Symphony Desktop User’s Guide

Getting Started with the AP-57

The AP-57 is modeled after a highly modified Ampex 601 tube preamp, part of a suitcase recording system from the late 1950s. The specific hardware unit used for modeling included the optional input transformer, a custom input attenuator and other custom tweaks.

Our AP-57 mic preamp emulation reproduces the complete experience using a 50s tube mic preamp the larger-than-life sound, the rich harmonics, and the rapid onset of distortion, especially when using high-output large diaphragm condenser microphones!

If you have a 50s tube mic pre, you probably have an in-line attenuator or two just to be able to record with a condenser mic without overloading the mic pre input. Then again, if you’re looking for a warm but present distortion, the 601 preamp gets you there quickly.

With our AP-57 emulation, you’ve got this choice as well - start with no pad, turn up the gain, and bask in the thick harmonics! If you’re barely cracking the Input gain but getting too much, engage the

-20 dB pad - you’ll be able to increase the gain with less distortion.

Once you’ve determined the pad setting, tap GL (Gain Link) to couple the Input Gain and Output Level controls to work together. The AP-57 emulation offers more extreme sounds than the other mic preamp emulations, so approach it with a creative mindset!

Apogee Channel FX Rack

The Apogee Channel FX Rack is at the heart of what makes Symphony Desktop unlike any other audio interface available. Thanks to the Channel FX Rack’s flexibility, Symphony Desktop can offer the wide array of innovative workflows described in Choose Your Symphony Desktop Workflows.

Specifically, the Channel FX Rack offers these unique features:

● The Channel FX Rack offers Apogee DSP processing, running on Apogee hardware DSP and natively on your computer’s CPU, at several points in the typical overdubbing signal path.

Processing is organized in the Channel FX rack by the following tabs:

1. Preamp tab - Apogee Alloy mic preamp emulation running on Apogee hardware DSP.

2. PrintFX tab - Apogee FX plugins running on Apogee hardware DSP.

3. MonitorFX tab - Linked Apogee FX plugins running both on Apogee hardware DSP and natively on your computer’s CPU.

Apogee Symphony Desktop User’s Guide

● The Channel FX Rack may be opened in your DAW, in Apogee Control software, or on the

Symphony Desktop touch screen - you choose the workflow that’s most convenient for you.

DAW Channel FX Apogee Control Channel FX Touch screen Channel FX

With the exclusive Channel Link functionality, all three locations may be synchronized to operate in parallel. Open the Channel FX rack in your DAW, link to a hardware input, and control everything from a single app window. You’ll no longer need to toggle between multiple apps during your session.

Channel Link

To get started with Channel FX, the first step is to set Channel Link from a Channel FX plugin opened in your DAW:

1. Open your DAW and create a mono track.

2. Set the DAW track Input selection to the Symphony Desktop hardware input your mic or instrument is connected to.

3. Open a mono Channel FX plugin, and set Channel Link to the same Desktop hardware input as the DAW track Input. This links the DAW track to the hardware input.

4. If you’re recording a stereo source like a keyboard, create a stereo DAW track, set the DAW track Input to the pair of Desktop inputs you’ve connected the keyboard to, open a stereo Channel FX plugin, and set Channel Link to the pair of hardware inputs used.

Apogee Symphony Desktop User’s Guide

Now that Channel Link is set, all remaining settings (with a few exceptions noted below) are

simultaneously available in the DAW plugin, in Apogee Control, and on Symphony Desktop’s touch screen.

Rack Controls

1. Direct Mixer Channel Strip (DAW Channel FX only) - When Channel Link is set to a hardware input, the corresponding Direct Mixer channel strip is displayed. This allows you to make hardware Input and Direct Mixer settings from your DAW window without toggling back to Apogee Control.

2. Preamp, Print FX, Monitor FX tabs - display the Preamp, Print FX and Monitor FX tabs: a. Preamp tab - Select Apogee Alloy mic preamp emulation and make settings. DSP processing

is applied destructively (i.e. permanently) in the analog input circuitry and immediately after A/D conversion. All downstream signal path stages, such as the Direct Mixer channel and the recorded DAW audio, are permanently affected by mic preamp emulation.

b. Print FX tab - Open up to 4 Apogee FX plugins to process hardware inputs before routing to

your DAW for recording. Like mic preamp emulation, all downstream signal path stages are permanently affected by Print FX processing.

c. Monitor FX tab - Open up to 4 Apogee FX plugins to process DAW playback (DAW Channel

FX) or Apogee Control Mixer throughput (Apogee Control Channel FX). If you’ve set Channel Link in the DAW Channel FX, the Apogee Control Mixer Channel FX is automatically and transparently instantiated for DualPath monitoring.

Apogee Symphony Desktop User’s Guide

3. Channel Link Dropdown (DAW Channel FX only) - Set the Symphony Desktop hardware input to

be linked to the DAW Channel FX plugin. See Channel Link for more details.

a. On the Apogee Control and Touch screen Channel FX Rack, a Channel Link indicator displays the

state of the Channel Link: blue indicates connected, while grey indicates disconnected.

4. DSP Load Meter - displays the current percentage of hardware DSP in use over all Channel FX racks and channels. For more information about Symphony Desktop’s DSP capabilities, see the DSP Plugin Instance Count chart.

5. Rack IN & Rack OUT Trims & Meters - Trim the input and output levels of the Monitor FX rack as displayed by the In and Out meters.

The functionality of these settings varies based on the currently selected tab:

Using the Channel FX Plugin

The Channel FX plugin is conceived so you can run every aspect of your session from the DAW window. Once you’ve configured Apogee Control for software or Direct monitoring, you can minimize the window or close the app.

To get a better understanding of how to use the Channel FX plugin, let’s step through a common recording situation - tracking lead, double, and background vocals.

In this example, you’d like to record the vocal with our AP-66 mic preamp emulation and a high pass filter that’s printed on the recorded file, all while monitoring with a bit of high end boost and a touch of compression. With the Channel FX plugin, that’s easy to set up and operate!

We’ll assume that you’ve configured your DAW for use with Symphony Desktop, and you’ve configured Apogee Control for Direct monitoring through Analog In 1. See Configuring Your DAW for specific instructions. Also, you’ve connected your mic to Analog In 1 and headphones to Desktop’s front headphone output.

In your DAW, open the Channel FX plugin and set Channel Link to Analog In 1. Now, Input 1 controls are displayed in the plugin, so you can turn on 48 volt phantom power, Soft Limit and other settings.

Click the Channel FX Preamp tab, then click the AP-66 icon. Now, set the Input gain and preamp output level - if you’re using a condenser mic, start with an input gain of 30 dB and an output of

-5 dB. Keep in mind that controls on the Preamp

tab are in effect remote controls for the mic preamp emulation that run on Symphony Desktop hardware DSP. This processing is applied before the signal is sent to your DAW, so it’s permanently recorded in your audio file.

Apogee Symphony Desktop User’s Guide

Next, click the Channel FX Print FX tab, then click

the “+” to add one instance of the Symphony ECS Channel Strip. Set the Hi Pass filter to 80 Hz - this setting removes any low end rumble that may be present in your recording space without removing any vocal frequencies. Like the Preamp tab, the Print FX tab is a remote control for plugins that run on Symphony Desktop hardware DSP. This processing is also applied before the signal is sent to your DAW, so it’s also permanently recorded in your audio file.

Finally, let’s set up the Monitor FX tab with a bit of high end boost and some compression. Click the Monitor FX tab, then click the “+” to add an instance of ECS Channel Strip. Set the High Shelf for +4 dB of boost at 10kHz, then the Compressor Threshold to -10 and the Ratio to 3:1. Plugins on the DAW Channel FX’s Monitor FX tab are running on your computer’s CPU.

Apogee Symphony Desktop User’s Guide

Once you’ve recorded your first track, you’ll

probably want to double it or record other vocal parts using the same settings you’ve carefully configured. The easiest way to do this is to duplicate the track in the DAW. When you open Channel FX on the new track, you’ll see a dialog to transfer the Channel Link from the previous track to the current one - click Proceed.

After recording all your vocal tracks, save the session - you can pick right back up later with the exact same Monitor FX settings, and you can even open the session using Built-in audio hardware and listen to the tracks - all Monitor FX plugins remain active.

Apogee Symphony Desktop User’s Guide

DAW Automation and Channel FX

Plugins running in the DAW Channel FX Monitor FX tab may be automated in your DAW. Automation parameters are dynamically added and removed to your DAW’s automation parameters list as FX plugins are opened and closed.

For example, when one ECS plug is opened in the DAW Channel FX Monitor FX tab, ECS parameters with the prefix Monitor FX 0 appear in Pro Tools’ Plugin Automation list.

Add a second ECS, and parameters with the prefix Monitor FX 1 are added to the list. Likewise, when a third and forth plugin is opened, automation parameters with a prefix Monitor FX 2 and Monitor FX 3 are added to the list.

Plugins running in the PrintFX tab cannot be automated.

Apogee Symphony Desktop User’s Guide

Channel FX On/Off Controls

Each On/Off control on the Channel FX plugin, including the DAW Bypass button, offers a specific function as described below.

1. DAW On/Off - the On/Off (or Bypass) button in your DAW plugin window affects plugins in the

DAW Monitor FX tab only. Print FX plugins and linked Apogee Control (hardware DSP) plugins are not affected.

2. Print FX Tab On/Off - This button toggles all the plugins in the Print FX tab on/off.

3. Monitor FX Tab On/Off - This button toggles all the plugins in the Monitor FX tab on/off. If the

Channel Link is set, then both DAW and Apogee Control (hardware DSP) Monitor FX plugins are affected.

4. Individual plugin On/Off - This button toggles each individual plugin in the Print FX and Monitor

FX tabs on/off.

5. ECS On/Off - In the Symphony ECS Channel strip, the EQ and Compressor sections each

have an On/Off toggle switch.

Apogee Symphony Desktop User’s Guide

Channel FX Mono/Stereo Configuration

When linking Channel FX plugins in your DAW and in Apogee Control (hardware DSP), it’s important to match the mono/stereo configuration of your DAW track and the Channel Link setting.

● If your DAW track is mono, the Channel FX plugin is mono as well - set Channel Link to one

hardware input - Analog In 1 or Analog In 2.

● If your DAW track is stereo, the Channel FX plugin may be stereo or dual mono.

○ If you select stereo, set Channel Link to a pair of hardware inputs; ○ if you select dual mono, set the left settings window to one hardware input of a pair

and the right settings to the other input.

○ The Left-Right settings selection found in Logic Pro X is shown below; consult your

DAW’s documentation for more information.

Apogee Symphony Desktop User’s Guide

Channel FX DSP Instance Count

The following chart indicates the number of Apogee FX plugins that may be opened simultaneously in the Print FX and Monitor FX tabs when the plugin is using hardware DSP.

● Print FX plugins always use hardware DSP

● Monitor FX plugins use hardware DSP when the Channel Link is set to a hardware input as

described in the Monitor FX and Dualpath Monitoring section of this guide.

Native instance count varies widely by computer make and models, but exceeds several hundred in most cases.

Choose Your Symphony Desktop Workflows

In the previous sections of this User’s Guide, the individual components of Symphony Desktop have been described in detail. This section describes how these components work together to form a sophisticated and efficient audio production environment.

All of us - producers, engineers and artists - have their preferences when recording and mixing, so Symphony Desktop offers a wide variety of compelling workflow options.

When setting up your Desktop-based system, you have two workflow decisions to consider:

1. Monitoring - how performers hear themselves while recording;

2. DSP Signal Processing - how and where audio processing like mic preamp emulation, EQ and

compression is applied. With a better understanding of some important workflow concepts, you’ll get the most from your Symphony Desktop.

To help you better understand the options available, the following glossary provides definitions of commonly used terms used in audio recording and processing:

A Glossary of Important Workflow Concepts

DAW (Audio Software) - The digital audio workstation, or DAW, is a specific type of audio software that offers sophisticated functionality, including the ability to choose an audio interface independently of the OS (operating system), manage multiple channels of input/output, support software or direct monitoring, support software plugins, and offers adjustable throughput latency.

Many software applications (Spotify, Youtube, for example) include audio input/output but don’t offer the critical functionality for completely supporting Symphony Desktop workflows. Nevertheless, these apps can work with Symphony Desktop when the OS is configured to use Symphony Desktop for audio input/output, as described here.

Latency - If you’ve done any recording at all with your computer or iPad, you’ve probably encountered that annoying delay that makes recording your performance difficult - it’s like you’re trying to record over a transatlantic phone call - that’s latency!

What is latency and why do you have to deal with it? Well, it starts with the fundamental process of digital audio - to convert audio waveforms to numbers for editing, processing, mixing and more, then convert numbers back into audio waveforms for listening. At each stage of your digital audio system analog to digital conversion, recording & playback in your audio software, plugin processing computations are performed on the digital audio that require time. Add up the total time from microphone input to headphone output, and the delay can significantly distract a performer as they record.

Buffer, aka IO Buffer, H/W Buffer - Most Digital Audio Workstation (DAW) software applications

have a buffer setting, which is potentially the largest source of latency in your system. The buffer setting offers a range from 32 to 2048 samples* to specify the amount of time the app spends to pass audio from the hardware interface, record it, process it through plugins and mixing, and finally pass it back to the interface for listening. Why wouldn’t you set the buffer to the lowest time, 32 samples? Then you’d get the lowest latency!

At the lowest setting, you’re giving the DAW the least amount of processing time. As your session grows and you add tracks, plugins and virtual instruments, the DAW won’t have enough time to complete the processing before the allotted time, and you’ll get clicks, pops and other symptoms of a DAW application under stress.

* Buffer settings may vary by DAW and sample rate.Thus, the Buffer setting is always a compromise between

lower latency and more processing power.

Monitoring - One of the fundamental workflow choices you’ll make is input monitoring - that is, how performers hear themselves while recording. Symphony Desktop offers two monitoring workflows, Software monitoring and Direct monitoring, which are described below in greater detail.

Native DSP Processing - When you open and run plugins in your DAW software, they use your computer’s native CPU processing power to perform the required DSP, and are said to be native plugins. If you’ve set the DAW Buffer to it’s maximum setting, you can run virtually thousands of Apogee plugins from a reasonably recent computer - there’s really a lot of native DSP processing power available from your computer!

Hardware DSP Processing - Even though you can open thousands of plugins running natively on your computer, there are a few instances where you need hardware DSP processing on board your audio interface.

● To fulfill the requirements of Direct monitoring, your audio interface needs hardware DSP for the Direct monitoring mixer and plugins;

● Hardware DSP can process an interface input before it’s sent to your DAW, so you can sculpt your sound and record the results.

Apogee Symphony Desktop User’s Guide

Apogee Ensemble Thunderbolt, Element Series and Symphony Desktop all offer onboard hardware

DSP.

Ideally, your plugins can run both as a native plugin in your DAW and as a hardware plugin in your audio interface’s Direct monitoring mixer. The Apogee Channel FX plugin is one of the very few that can!

Apogee Channel FX Plugin - Apogee Channel FX is the collection of hardware and native DSP processing available in your Symphony Desktop-based audio production environment. The following unique capabilities of the Channel FX plugin unlock Desktop’s innovative workflows:

1. Runs both on Symphony Desktop hardware DSP and natively in your DAW

2. Link Channel FX running natively in your DAW and on hardware DSP.

Apogee FX Plugins - the collection of Apogee plugins that can be opened in the Channel FX plugin:

1. Pultec EQP-1A Program Equalizer

2. Pultec MEQ-5 Midband Equalizer

3. ModComp Visual Compressor/Limiter

4. ModEQ 6 Parametric EQ

5. Symphony ECS Channel Strip

6. Opto-3A Compressor

Print FX - the term “Print FX” or “printing” is used in this guide to specify DSP processing that is “destructive”, or permanently applied to the audio file being processed. For example, when EQ processing is “printed”, it becomes a permanent and irreversible characteristic of the audio file.

Monitor FX - in contrast to Print FX, Monitor FX are on channel playback, and are thus “non-destructive” - you can always change your mind. As you become more confident with plugin processing, you may choose to print some effects while monitoring through others.

DualPath Monitoring - All of Symphony Desktop’s innovative features work together to bring you the DualPath monitoring workflow, the easiest way to achieve direct monitoring with plugins all from your DAW window.

Apogee Symphony Desktop User’s Guide

Monitoring Workflows

The first workflow choice you’ll make concerns monitoring - software monitoring or direct monitoring.

Software Monitoring

When your system is set up for Software monitoring, the audio that the performer hears is routed through the DAW, including plugins and mixers, and thus incurs the maximum latency of the system, as shown below.

● Pros - This is the simplest monitoring workflow, where most settings are made in the DAW window.

● Cons - It’s necessary to set the DAW IO Buffer setting to a compromise between lower latency and maximum CPU plugin processing - the lower the latency, the fewer native plugins may be run.

If you have a powerful computer and your sessions use a moderate amount of plugin processing, you may be able to find a Buffer setting that’s low enough that latency isn’t a problem but high enough that processing is completed without issues.

Direct Monitoring

Direct Monitoring, aka Low Latency Mixing - When the processing demands of your session require a higher Buffer setting that causes disruptive latency, Direct monitoring lets performers hear themselves through a separate mixer running on hardware DSP and controlled in Desktop Control software. The Direct mixer avoids the latency-inducing round trip through the DAW. To avoid double monitoring, the DAW must be configured so incoming audio to be recorded is NOT monitored through the DAW.

● Pros - Low latency and maximum plugin power - the DAW IO Buffer may be set to its maximum value for the greatest number of native plugins without an effect on latency. Latency remains virtually non-existent through the direct monitoring mixer.

● Cons - With many audio interface systems, it’s necessary to toggle between your DAW window and a separate direct monitoring mixer app. Adding non-destructive plugins while Direct monitoring can become unwieldy. Apogee’s proprietary DualPath monitoring workflow, described here, addresses these disadvantages, so you benefit from the advantages without suffering the disadvantages.

Apogee Symphony Desktop User’s Guide

DSP Processing Workflows

Symphony Desktop also includes flexible and powerful hardware and native DSP processing that supports a wide range of innovative workflows - 1) Apogee Alloy mic preamp emulation; 2) Print FX;

3) Monitor FX (DualPath Monitoring); and 4) Native operation.

DSP Processing workflows are independent of your monitoring workflow, with the exception of DualPath monitoring - Apogee’s revolutionary approach to Direct monitoring with plugins.

Apogee Alloy Mic Preamp Emulation

Apogee Alloy mic preamp emulation employs circuitry found in Symphony Desktop’s Analog inputs plus onboard hardware DSP to bring the warmth and character of classic mic preamps to your recordings.

The analog circuitry is a key component of the emulation processing, so mic pre emulation is available only on Analog In 1 & 2 mic, line and instrument inputs.

Mic preamp emulation is inserted into the signal path before the direct monitoring mixer and the “send” to your DAW, as shown below. Emulation processing is printed, i.e. it permanently modifies the audio signal, regardless of your monitoring workflow (Software or Direct monitoring). Of course, a hardware mic preamp would permanently change the audio as well!

To apply Alloy mic preamp emulation, open the Channel FX on the DAW channel(s) you’re recording on. Set the Channel Link setting to match the DAW channel input setting as described here - now the Preamp, Print FX and Monitor FX tabs appear at the top of the plugin. Click Preamp and choose your preferred emulation.

Apogee Symphony Desktop User’s Guide

Print FX

With Print FX, you can shape your sound as you record it using up to 4 Apogee FX EQ, compression and saturation plugins running on Symphony Desktop hardware DSP.

Print FX processing may be applied to Analog Inputs 1&2.

Print FX plugins are inserted in the signal path before the direct monitoring mixer and the “send” to your DAW, as shown below. Like mic preamp emulation, Print FX processing permanently modifies the audio signal regardless of your monitoring workflow (Software or Direct monitoring).

To apply Print FX processing, open the Channel FX on the DAW channel(s) you’re recording on. Set the Channel Link setting to match the DAW channel input setting as described here - now the Preamp, Print FX and Monitor FX tabs appear at the top of the plugin. Click the Print FX tab, then load up to 4 Apogee FX plugins.

Monitor FX & DualPath Monitoring

With Monitor FX and DualPath monitoring, users experience workflow benefits that have previously only been available with Avid Pro Tools HD - 1) very low latency, even when the DAW IO Buffer size is high 2) simple, non-destructive plugin workflow - open a single plugin in your DAW that processes monitoring and playback 3) control from a single app window - your DAW.

When you open Monitor FX plugins in a DAW Channel FX plugin and set Channel Link, the plugins are actually inserted in two different signal paths - 1) in the DAW Playback signal path and 2) before the direct monitoring mixer but after the “send” to your DAW, as shown below.

When recording, the performer hears himself through Monitor FX running on hardware DSP; playback, on the other hand, is heard through Monitor FX running natively in your DAW. Most importantly, the two plugins are control-linked, so settings made in one Channel FX plugin are mirrored to the other Channel FX plugin.

All this happens automatically and transparently when you open the Channel FX plugin in your DAW and link it to a hardware input. We call this revolutionary workflow DualPath Monitoring.

Apogee Symphony Desktop User’s Guide

Monitor FX & Software Monitoring

If you’ve configured your system for Software monitoring, you can still benefit from Monitor FX, even when Symphony Desktop isn’t connected to your computer. Plugins opened in the Monitor FX tab in your DAW are powered natively by your computer’s CPU, so they work even when you’re using Built-In headphone outputs or other audio hardware.

Of course, all Apogee FX plugins may be run directly in your DAW, without opening them in the Channel FX plugin. These plugins are powered natively by your computer’s CPU, so they work even when you’re using Built-In headphone outputs or other audio hardware.

Additional Workflows

Mix Inputs Before Recording

You can use the Symphony Desktop Mixer to mix hardware inputs and record the mixed output, using the Assign to SW (software) Inputs dropdown in the Apogee Control mixers. The possibilities include:

1. Use two mics to capture an instrument and record a blend to one DAW track;

2. Pan a single input to the center of a stereo output for audio apps without panning functionality.

In the workflow depicted above, set Direct Mixer 1 Assign to SW Inputs dropdown to Software Inputs 1-2. Now, the output of Mixer 1 is routed in place of Analog In 1-2 to your DAW’s input.

Direct Mixer 2 is used for Direct monitoring, to mix hardware inputs with Playback outputs from the DAW. It looks complicated, but once configured it’s pretty straightforward.

CAUTION - If Mixer 1 Playback inputs are active, you may create a feedback loop that results in a loud and potentially damaging oscillation. MUTE the Mixer’s Playback inputs.
