Page 4 NOTES FOR IRIS 1 USERS Iris 2 has been completely redesigned and contains numerous new features and improvements that were not available in Iris 1. For this reason, Iris 2 installs in its own separate location with a separate library of samples and patches. We recommend that you keep Iris 1 on your system to recall original sessions that used Iris 1, because it will always have its own unique sound and character that you may want to recall.

You will need access to a device with internet access, but it need not be the computer you are authorizing. After opening Iris 2 and launching the Authorization Wizard, the following steps will complete the authorization process offline: 1.
QUICKSTART The best way to learn Iris 2 is to start making music with it. You can instantiate Iris 2 as a plug-in in your favored audio editing software, or simply open the Iris 2 standalone application. Iris 2 works best when used in conjunction with a MIDI keyboard controller, but can also be used without one. Once you’ve installed and authorized Iris 2, an “Introduction to Iris” window will pop open when you open, offering you links to this user manual and videos online that can help you get started.
Presets are organized into useful folders like “Leads” and “Pads,” and can be previewed by clicking on a preset to load it, then simply playing notes on your MIDI controller or the keyboard displayed at the bottom of the Iris 2 window. As you explore all the patches included with Iris 2, you’ll notice there are eight Macro Controls located to the right side of this window.
Page 12 UI OVERVIEW Iris 2 has a dynamic new user interface (UI) designed to make every control easily accessible and easy to use. In addition to being resizable, you can customize the UI to work best for your computer and workflow by hiding, revealing, or undocking different panels. Along with MIDI Assignments, the UI layout you set up will save between sessions so Iris will look and feel the same each time you use it.
Global Panel: Located at the top of the Iris 2 UI, this panel contains basic controls for loading, saving, and displaying Patches, as well as voice modes and master controls for Glide (portamento), Intensity, and Output. From here, you can also navigate between Sample Pool views and access the most important mix controls for each sample, like Solo, Mute, and Gain. Sample Panel: This panel offers parameters for control over whatever sample you are viewing in the spectrogram area.
Page 14 INTRODUCTION Iris 2 | ADJUSTING PARAMETERS IN IRIS 2 Modulatable Knob Non-modulatable Text Control Non-Modulatable Knob To adjust one of these controls, you can: 1. Click and drag up or down on the knob or text value using your mouse or trackpad. 2. Click on the knob or text value and then use your mouse scroll wheel or trackpad. 3. Click on the knob or text value and then use your keyboard up/down arrows. 4.
Browser and Macro Panels To access the Simple or Full Browser, click on the Patch Display in the Global panel. SIMPLE BROWSER Iris’s Simple Patch Browser is designed to allow you to explore the extensive Iris 2 Sound Library in an easy and concise manner. Categories will be displayed on the left, the patches on the right. Select a patch and play it with your MIDI keyboard or the keyboard located at the bottom of the Iris 2 window to audition the sound.
Undocking the Patch Browser Iris’s Patch Browser can be undocked and resized to fit your screen by clicking on the icon to the left of the Close button. Click the same icon again to bring the Patch Browser back into the main interface. MACRO CONTROLS Iris 2 includes eight Macro Knobs to allow for easy manipulation of several parameters simultaneously.
When viewing samples in the Full Browser, the folders of your Sound Library will be shown in the left column and the individual sample files for the selected folder in the right column. Use the expand/collapse arrows or double-click on a folder to access any sub-folders in your sample library. To load a sample into one of the sample pools, click and drag any sample onto the areas along the right labeled “Sample 1,” “Sample 2,” “Sample 3,” and “Sample 4,” or drag the sample directly into a spectrogram.
Page 18 Export In order to easily share and spread patches between machines or users, click the Export button in order to save your currently loaded patch into a specified directory. As mentioned above, the exported .IRIS patches will be saved with their pertinent audio samples inside of the .IRIS patch file for easy loading onto other machines. Remove Click the Remove button in order to delete the currently selected patch from your Sound Library.
Samples and Oscillator Waveforms Your purchase of Iris 2 includes over 11 GB of samples as .WAV files that you can use both in Iris 2 and in other software. These collections include samples from classic synthesizers, acoustic instruments, and unique abstract sounds and environmental textures that lend themselves particularly well to musical sound design. The delineation between samples and oscillator waveforms (OSC WAVs) is purely organizational.
Samples and OSC WAVs can be loaded in a multitude of ways: 1. From the Full Browser, you can: ♦♦ Preview and select a sample or OSC WAV, then simply drag it to one of the areas labeled “Sample 1,” “Sample 2,” etc. ♦♦ Click one of the Load buttons below each Sample section to open an OS browser to use any .WAV or .AIF file on your computer. 2.
Global Panel At the very top of the Main Interface, we see a display of some of the most critical Iris 2 controls, called the Global Panel.
Four useful patch control buttons are located underneath the patch Display: Random will choose a random patch. This is intended to help you explore the vast library of Iris 2 patches and perhaps even be inspired by a patch you hadn’t discovered previously. New will create an empty “blank slate” for you to build a new patch on. All controls will revert to their default states, and all sample pools will be empty.
Page 23 VOICE MODES Next to the undo/redo controls are the Voice Mode controls, Global parameters knobs, and master output level meter: The Voice Mode controls allow you to choose between Mono, Legato, and Poly voice structures. Mono means only one pitch can be played at a time. Every note that is played will retrigger envelopes and LFO attack. Legato means only one pitch can be played at a time, but playing notes consecutively will not retrigger envelopes or LFO attack.
MIDI ASSIGN Pressing the MIDI Assign button gives you the ability to assign knobs and sliders on your external MIDI controller to many of the parameter controls in Iris 2. When you click “MIDI Assign,” you’ll notice the names of all the parameters eligible for MIDI control will light up yellow, but clicking on the parameter name will turn the name red. From here, you simply twist a knob or move a slider on your MIDI controller, and that controller will attach to that parameter.
Page 25 POOL SELECTION AND MIX CONTROLS All the way to the left of the Global Panel are the Sample Pool Selectors and Balance Controls: Each Sample Pool Selector is labeled “1-4,” and has controls for Solo, Mute, and Gain located right next to the selector. This allows you to quickly navigate between samples while still having access to important controls for every sample all the time.
Sample Panel The Sample Panel is one of four collapsible panels in the main Iris 2 UI. Four versions of the Sample Panel also appear as part of the Mix Window: one for each sample pool. SAMPLE LOADING The sample view contains important controls for loading and manipulating each sample. At the very top is the Sample File Display which displays the name of the loaded sample. If there is nothing listed in this area, it means there is no sample currently loaded.
SAMPLE PLAYBACK CONTROLS Once you have loaded a sample, now you can decide how it will play back. The Playback menu gives you four simple options. You can set your sample to play forwards, forwards then backwards, backwards, or backwards then forwards (the titles of these modes are abbreviated in the interface for brevity). You can also choose whether you want your sample to loop or play as a “one-shot” by pressing the Loop button located next to the Playback Menu.
To the right of the Pitch Mode selector is a button labeled “Retrigger,” which is engaged by default. With this engaged, every new “note on” MIDI message will start playback of the sample over again (notes that had been played previously may continue to sustain if their respective amplitude envelope is set with a long decay time). With this disengaged, you can play through multiple pitches and each one will pick up at the sample location where the last one left off.
Page 29 SAMPLE MIX CONTROLS Below the Tune controls are knobs for Pan and Gain. These are also both modulatable. Pan is a linear control that controls the left/right balance of the sample across the stereo spectrum. Like the tuning controls, its default position places the sound at the center of the stereo spectrum when the knob pointer is positioned straight up. Note: Because Iris 2 supports stereo samples, the Pan control will only affect the balance of that stereo sample.
An effect must be turned on before its respective knob will become operable. There is a power button at the top-left above each knob which can turn on the effect. The image below shows the Distortion effect is turned on, with the knob operable and ready to be turned up (or have modulators applied). We can see the Chorus effect is turned off, signified by the power button and knob being greyed out: These power buttons also give you a quick way to bypass the effects without changing your send values.
Master Panel The Master Panel is another of the four collapsible panels in the main Iris 2 UI. It also appears in the Mix Window to the right of the four Sample Controls for each sample pool. MASTER MIX CONTROLS Like the Sample Mix Controls, there are two modulatable knobs located in the Master Panel to control the pan and gain of the entire mix of samples.
Gain is a logarithmic control and adjusted in decibels. You will also notice that attached modulators will affect the gain control (and be represented on the outer rings) in a logarithmic way. There is a range of 105 dB in the Gain Control (-Inf to +6 dB). Velocity can easily be applied to master gain with its own dedicated knob located above the Master Gain control, and is applied at +60.00% by default when starting a new preset. The range of this velocity knob goes between -100.
Using the Spectrum Analyzer, you can easily see the precision of our Spectral Filters. For example, on the Spectrogram pictured below, we see a simple square wave sample with a selection made with the Frequency Selection tool between 1k and 5k, and its corresponding Spectral Analysis: The Spectrum Analyzer displays your entire mix, including any master filtering or effects you have applied, and reflecting any solos or mutes you have engaged.
The filter models are grouped into four types of modes (thus “Multi-mode”): Low Pass: Frequencies above the cutoff frequency are filtered out with a gentle slope. (The low frequencies pass through without being filtered.) High Pass: Frequencies below the cutoff frequency are filtered out with a gentle slope. (The high frequencies pass through without being filtered.) Band Pass: Frequencies above and below the cutoff frequency are filtered out over a gentle slope.
Page 35 Screaming Peak (Peak): Less of a filter and more of an analog resonant boost, Screaming Peak provides strong saturated-valve resonant peak at the cutoff frequency specified. Use the Resonance control to adjust the strength of the peak. Note: New York and Tokyo filter models use 3-4% more CPU power than the others. Master Filter Controls The Master Filter has two modulatable controls: Filter Cutoff and Filter Resonance. Filter Cutoff is the frequency at which the filter begins to take effect.
The four modulatable-effect dry/wet knobs located at the bottom panel will only be activated when Master Mode is enabled. Master Mode can be enabled by clicking on the Master button next the Master Effects label. When the Master button is lit up in a blue color, that indicates that Iris 2 effects are in Master Mode. The text in the Master Effects Controls will also become white. All text and knobs are greyed out when Master Mode is disabled.
Mix Window The Mix Window provides an overview of the primary controls for all four samples and the master section: To access this window, click on the small button to the far right of the Global Panel labeled “Mix.” The Mix Window opens as a completely separate window that allows you to close the Sample and Master panels in the main UI and view the spectrogram with more detail. The Modulation Panel can also be undocked so it can be set up near the Mix Window and open up even more space in the spectrogram.
Spectrogram Area and Tools Panel Some of the most unique features in Iris are the Spectral Filters and the visual way of interacting with them through a spectrogram. A spectrogram is a graph that displays frequency on the x-axis, and time on the y-axis, with the amplitude of each frequency represented by contrast.
Page 39 WAVEFORM OVERVIEW At the top of the spectrogram is the Waveform Overview. This displays the entirety of your sample for quick overview and navigation. If you are zoomed in to a part of the sample on the spectrogram itself, that area will appear as boxed in the Waveform Overview. You can use your mouse to move this boxed area across your sample to maintain zoom level while scrolling across.
clicks and pops at your loop points. You can override the Intelligent Zero Crossing feature by modifying Loop Start/End points at their respective numeric value controls located below the spectrogram. Crossfade: This allows you to apply crossfades to your loop, and is set by default to 176 samples to minimize any potential clicking. The crossfade will be indicated with diagonal lines over the spectrogram. Offset: This control changes where playback will begin in the sample.
Page 41 Selection Tools These tools allow you to make draw in selections on the spectrogram, and are the key to Spectral Filtering: Time Selection Tool: Allows you to make rectangular time selections in the horizontal plane across the entire spectrum. This is the default tool for making selections in Iris. Time and Frequency Selection Tool: Allows you to make rectangular selections across time and frequency.
Page 42 Selection Removal Tools Eraser Tool - Similar to the paintbrush tool, the Eraser Tool allows simple freehand erasing with a circular brush. An adjustment for brush size will appear next to the control once it has been selected. You can also adjust brush size with your mouse wheel by holding down Control + Command at the same time. Note: The Eraser tool only works after some initial selection has been made. Clear All Selections - Removes all filtering selections from the Spectrogram.
SPECTROGRAM MENU Right-clicking on the spectrogram (or any of the pool selectors) brings up a menu of additional options to help with your workflow: Copy/Paste Sample: Quickly copy and paste samples across the sample pools. Copy/Paste Sample and Selection: Copy and paste both the sample and any selections you have made on the spectrogram. Because spectrogram selections are made across time relative to the sample itself, selections cannot be copied without also copying the sample they refer to.
All View The All View gives you a quick and editable overview of all your currently loaded samples and their selections. Copyright © 2014 iZotope, Inc. All rights reserved.
SELECTING A POOL Single-click inside of any sample to view the corresponding Sample Panel and parameters for that sample. This includes all parameters within the Sample Panel, as well as the Loop Start/End, Crossfade, Offset, and Delay parameters represented in the Spectrogram Area. A thin white line will surround the sample whose parameters are currently being shown. In the image above, we can see that Sample One is currently selected.
Keyboard Panel The Keyboard Panel serves both as a real-time control for auditioning sounds in Iris 2, and also the area where you can set the mapping, split points, and root notes for each sample as well as the pitch-bend range. KEY MAPPING In the preceding image, we see the Key Mapping panel open. This is accessed by clicking on the small “up” arrow at the far left of the keyboard panel.
PITCH AND MOD WHEEL In the remainder of the keyboard panel, we see indicators for Pitch and Mod Wheel at the far right. These meter in real time any movements made by these MIDI controllers. You can also click and drag in these areas to apply or test these effects in real time. One unique and useful feature of Iris 2 is the ability to set Pitch Bend Range with different amounts in either direction (up to two octaves each way, measured in semitones).
Modulation System Modulation brings the sounds in Iris to life, giving them movement and expression that wasn’t available in Iris 1. With Iris 2 we created an extensive modulation system that is intended to give users the flexibility and connectivity of a modular synth. Iris 2 has four types of Modulation Sources: LFOs, Envelopes, MIDI Expression Controllers, and Macro Knobs. These Modulation Sources can be connected to over 100 modulatable parameters in Iris 2.
Page 49 APPLYING MODULATION TO PARAMETERS DRAG Drag & Drop DROP ADJUST Modulation can also be assigned by dragging the Modulation Source to the desired parameter. Simply click on the four-arrow icon located next to a Modulation Source button and a circle will appear that can be dragged and dropped onto a Modulation Input. You can click anywhere on the interface (that isn’t a Modulation Input) to get rid of the Modulation Assignment Circle.
Page 50 2. Right-click on the knob or slider, select the Assign sub-menu and then choose an LFO, Envelope, Macro Knob, or Controller source from the sub-menus. The modulation source will be applied to the first available Modulation Input slot. ADJUSTING MODULATION RANGE After applying a modulation source to a Modulation Input slot, two things will happen: 1. The slot turns into a Modulation Range knob to control the direction and amount of modulation applied to the knob. 2.
Page 51 MODULATION Iris 2 | REMOVING MODULATION REMOVING MODULATION Clear All Right-click on the Modulation Knob or Slider that has modulation applied to it. Choose Clear Modulation from the contextual menu. This will clear all applied modulation slots. Clear a Specific Modulation Range Knob Right-click on a specific Modulation Range knob and choose None from the contextual menu to remove the modulation applied to that modulation slot.
MODULATION COMBINE MODES Iris 2 modulation sources can be combined in one Modulation Knob or Slider by four means: Addition, Multiplication, Min, or Max. Modulation slots 1 and 2 can be combined in one mode while Modulation slots 2 and 3 can be combined in another mode. Add By default, when multiple modulation sources are applied to one Modulation Knob or Slider, the values of those modulation sources will add together.
Page 53 Max This mode will select whichever value is the greater between the two modulation sources at any given moment. LFOS When a Low Frequency Oscillator (LFO) is applied to a Modulation Knob or Slider, that LFO will cause the parameter value to oscillate in a bipolar fashion around the center point of the knob. This pattern is decided by the shape of the LFO wavetable chosen in the LFO Type menu. By default the LFOs will start with a table of sine waves.
Page 54 Restart (on by default): With Restart turned on the LFO will restart its cycle each time a new note is played. With restart turned off as long as a voice is playing in Iris that LFO will continue to oscillate. This allows for slow-moving modulation over time while playing shorter notes. Rate: This controls the speed at which the LFO will cycle through its waveform. The faster the rate, the faster your parameter will move between values.
Digital If you’re looking for a modern hard-edged modulation sound, the Digital category has a range of stairs, pyramids, ramps and pulses to add an angular grid-like sound to any parameter. Turn on LFO Sync to further lock these shapes to your DAW’s grid and tempo. Multiply To move beyond standard modulation and into the realm of Frequency Modulation (FM) and Amplitude Modulation (AM) synthesis, the Multiply shapes provide sped-up versions of the Analog Sine, Saw, Square, and Triangle shapes.
Attack controls the speed at which the gain is turned up from silence to full volume. The default setting is an instantaneous 0 milliseconds. Setting the attack to 500 ms would cause the gain to ramp up to full volume over half a second (500 ms). Decay controls the speed at which the gain falls back down to the Sustain level. This value is in milliseconds. Sustain controls the value that will continue for the remaining duration of the note that triggered this envelope.
MIDI EXPRESSION CONTROLLERS Drag and Drop one of these icons to assign a MIDI controller to a Modulation Knob or Slider You can assign MIDI CC to nearly all of the parameters in Iris 2 using MIDI Assign. However, expression controllers like Key Tracking, Velocity, and Aftertouch can’t easily be assigned using MIDI Assign, so they’re included in the modulation system for easy attachment and range setting.
Aftertouch is just what it sounds like. After a note has been articulated, you can apply more pressure to a key as you hold it and Aftertouch will output a higher value. In turn, less pressure outputs a lower value. Unlike Key Tracking and Velocity, Aftertouch isn’t attached to anything by default. However, some creative uses could include: A vibrato effect 1. Attach an LFO to Fine Tune on each active sample. 2.
MACRO CONTROLS Click on the symbol to reveal the Macro Controls Window Drag and Drop one of the icons above to assign a macro control to one or more parameters Macro controls give you the ability to adjust multiple parameters at once from one knob. They’re particularly useful when you use the MIDI Assign function to assign them to physical knobs on your MIDI controller.
Effects Iris 2 has four dedicated effects processors that provide users with a selection of iZotope’s award-winning effects chosen specifically for synthesis and sound design. While many users may choose to use additional effects plug-ins in their signal path after Iris 2, these effects and their settings save right along with patches to be easily shared, recalled, and used again in other projects. Also, nearly all of the parameters for each effect are fully modulatable. Copyright © 2014 iZotope, Inc.
SEND AND MASTER MODES These effects processors can be selected to operate in Send Mode (each sample can have a unique amount of each effect), or Master Mode (the entire mix of all samples is subject to the effect). Only one mode (send or master) can be used at a time. To select between Send and Master effects modes, simply use the buttons in Master Panel labeled “Send” and “Master.
DISTORTION Iris 2 includes six of the finest distortion algorithms from Trash 2, from classic amp modeling to radical digital numbercrunching. Distortion Types Tube is an emulation of tube saturation with a mix of even and odd harmonics. Saturate is a subtle crossover distortion inspired by push-pull style amplifiers. Clipping is a harsh, solid-state style distortion. Asymmetrical is a radical distortion that exhibits an extreme response to the incoming audio.
CHORUS The Chorus module in Iris 2 is modeled after a classic ’80s digitally controlled synthesizer with a famously rich chorus. It can be used to add subtle, unison-style effects or radical spreading and flanging effects. Chorus Parameters Depth - controls the depth of the pitch wavering applied in the Chorus effect and therefore the amount of Chorus that is applied. Rate controls how fast or slow the Chorus-affected signals will modulate in pitch.
STEREO DELAY Iris 2 actually contains two distinct delay models: the default ultra-clean digital delay, and a classic analog delay model which includes moderate tape-style saturation when used aggressively. Delay Parameters Sync locks delay times to the Host Tempo for distinct rhythmic delay effects. Delay Time (L/R) determines the amount of time that will pass before each successive repeat of your incoming audio.
REVERB This Reverb is a carefully selected model of a Plate Reverb, offering a rich warmth that complements the extensive acoustic and environmental samples of the Iris 2 library as well as the analog oscillator waveforms. Reverb Parameters Size controls the overall amount of reverb decay that will be used. Larger Size values result in much longer, larger reverb tails, while smaller Size values create very quickly decaying and tight room ambience.
Configuring Iris 2 Iris 2 can operate both as a plug-in within an audio editor like Ableton Live, Logic, ProTools, or FL Studio, or as a standalone application. This chapter outlines some of the options available to customize your Iris 2 workflow, and make some recommendations on how to optimize your Iris 2 patches for optimal CPU performance.
Check for Updates: This option selects the frequency with which Iris 2 looks for version updates. Choose between daily, weekly, monthly, and never. Click “Check Now” to instantly check if your version of Iris is currently up to date. This will open an accessory application called the iZotope Updater, which will also look for new versions of other iZotope products you have on your computer.
Show Frequency Ruler: Shows a frequency ruler along the left side of each sample in the main display. There are different options for the way in which frequencies are represented in the spectrogram: Linear: Linear scale means that Hertz are linearly spaced on a screen. Mel and Bark: Mel and Bark scale are frequency scales commonly found in psychoacoustics, i.e. they reflect how our ear detects pitch. They are approximately linear below 0.5 kHz and approximately logarithmic above that.
Clear selections on sample load: When checked, this removes any Spectral Filter selections made on the spectrogram when a new sample is loaded. For example, if you make a complex Spectral Filter selection and want to try a new sample with this selection, you would uncheck this box. Radius RT Options When Radius RT is used as a sample playback mode, CPU performance is influenced significantly by the range and limits within which Radius RT must function.
MIDI note input functions as a stream and therefore, even if only four voices are available, hitting 10 notes on your keyboard will still require that we instantaneously try to process those 10 notes. As such, while using Radius RT, you may find that hitting many keys at once will give you worse performance, even if your Radius RT options are set to be more conservative. Reset Radius RT Settings Restores your Radius RT settings to Iris 2’s factory defaults.
Freezing or Bouncing Tracks Freezing or bouncing your Iris 2 tracks offers you the most substantial gains in CPU performance. Check your audio editor’s user manual for instructions on how to do this. Hide the UI Iris 2 offers real-time metering for numerous parameters including modulation dots around modulatable knobs, morphing wavetable shapes, playheads moving across the spectrogram, and a spectrum analyzer. These can be resource-intensive.
Lower sample rate/bit depth With sessions at higher sample rates and bit depths, fewer instances of Iris 2 will be possible before encountering CPU issues. Store samples on a solid state drive As with all sample-based instruments, streaming media off a hard drive can only happen as quickly as the hard drive can access the files. Solid-state drives offer optimum performance.
