What You'll Learn

Importing iZotope Iris 1 samples into Iris 2
IZotope's Iris 2 is a sample-based synthesizer that allows users to transform any sound into an instrument. It is a significant upgrade to its predecessor, Iris 1, with numerous new features and improvements. Due to these enhancements, Iris 2 installs in a separate location with its own library of samples and patches.
When upgrading from Iris 1 to Iris 2, it is recommended to retain Iris 1 on your system. This is because Iris 1 patches can be loaded into Iris 2, but some parameters, such as modulation and sample locations, may require reassignment due to the new features in Iris 2. Additionally, for sample content not included with the Iris 2 content packs, users will be directed to a missing samples dialogue, allowing them to relink their samples to the original .irss files. However, these files will not be converted to WAV files in the new Iris 2 library.
To ensure a smooth transition and maintain access to previous work, users are advised to keep both versions of the software on their system. This way, they can easily recall original sessions created with Iris 1 while exploring the new capabilities offered by Iris 2.
While Iris 2 offers significant advancements, it is no longer available for purchase from iZotope. The company has discontinued sales to focus on developing new products and features. However, users can still access resources, tutorials, and tips for Iris 2 on the iZotope website and other platforms, enabling them to maximize their use of the software even though it is no longer being updated or sold.

Using the modulation upgrade
IZotope's Iris 2 comes with a major upgrade to modulation, offering extensive inter-connectivity and a redesigned system. This upgrade provides near-modular flexibility, allowing users to explore inter-modulating LFO frequencies, adding delay and feedback with keyboard tracking, and more. The modulation system features simple drag-and-drop style mapping, enabling users to scale the level of modulation and further manipulate depth using a target circle and ring.
With over 100 modulatable parameters, the upgrade offers a wide range of creative possibilities. Users can modulate the shape of an LFO, and all parameters can be modulated and automated with minimal artifacts. iZotope has included four master effects and four insert effects per sample pool, with effects such as distortion, chorus, and stereo delay.
The modulation upgrade enhances the overall functionality of Iris 2, making it a desirable improvement for many users. However, it is important to note that some parameters, including modulation and sample locations, may require reassignment when importing Iris 1 patches into Iris 2.
Despite the improvements, some users have expressed concerns about the lack of time-stretching capabilities in Iris 2, which could have been a significant addition to the modulation upgrade.

Creating a luscious vocal pad
IZotope's Iris 2 is a powerful tool for creating and manipulating vocal pads. With its redesigned interface and new features, it offers a wide range of possibilities for sound designers and musicians alike. Here is a step-by-step guide to creating a luscious vocal pad using Iris 2:
Step 1: Load Iris 2 and Choose Your Vocal Sample
Load Iris 2 in your DAW (Digital Audio Workstation) and click on Layer 1 in the top right corner. Browse and select your desired vocal sample. Iris 2 will automatically detect the root note of the sample, eliminating the need to manually set the pitch.
Step 2: Find the Perfect Loop
Under the Spectrogram display, there is a slider that blends the waveform view with the spectrogram. Adjust it to make the waveform visible. Now, find a loop within the sample that sustains a single note and sounds appealing. Add a MIDI clip on Iris's channel, draw a C3 note, and loop it.
Step 3: Fine-tune the Start Position
Listen to the vocal sample and identify the section where the singer drops down a few notes. Drag the start position locator to the beginning of this phrase. Leaving a bit of pitch transition at the start will create a smooth slide into the note.
Step 4: Create Another Layer with Spectral Filtering
Right-click on Layer 1 and select "Copy Sample". Then, paste it into Layer 2. In the Layer 2 edit window, select the brush tool and draw a line around the loop section from Layer 1. This adds shimmering tops and enhances the sound.
Step 5: Enhance with Harmonic Blobs
Experiment with adding blobs in the frequency spectrum, such as from 700Hz to 7kHz, to create harmonic enhancement. Adjust the settings to find the perfect sound. Add reverb to this layer by changing the master FX mode to "Send" and turning on the Reverb effect.
Step 6: Finalize with a Unique Top-End Texture
For the last layer, select a unique sound, such as the sound of a tap running, to add a distinct top-end texture. Adjust the Coarse pitch knob to make the sound brighter. Change the Playback mode to "Backwards" for an otherworldly feel. Use the brush tool to draw a wavy line at the top of the frequency band, focusing on the upper part of the spectrum.
Step 7: Dial in the Effects
Add more Reverb and Chorus to the final layer, and adjust the Gain to ensure it blends well with the other layers. Give this layer a pitch envelope for a "wash-over" effect. Adjust Envelope 1's settings, including the Attack value, to create a smooth pitch transition.
With these steps, you have crafted a luscious vocal pad using Iris 2. Feel free to experiment with different vocal samples, effects, and settings to create your own unique soundscapes.

Layering and mixing samples
IZotope's Iris 2 is a sample-based synthesizer that allows users to transform any sound into an instrument. It is an upgrade from its predecessor, Iris 1, with numerous new features and improvements. One of the key features of Iris 2 is its ability to layer and mix samples simultaneously.
Iris 2 allows for four simultaneous layers of samples, which can be populated with various sounds such as synth waveforms, cellos, circuit-bent toys, or even everyday sounds like onions being peeled. This provides users with a vast array of options for layering and mixing samples to create unique and complex sounds.
While the manual element of populating layers in Iris 1 has been eliminated in Iris 2, each layer can still be individually customized. Users can confine specific layers to certain key ranges, ensuring that the samples mix harmoniously without clashing. Additionally, the improved modulation capabilities in Iris 2 enhance the overall mixing process, allowing for a more dynamic and nuanced sound.
To facilitate the layering and mixing process, Iris 2 provides a brand-new spectrum analyser in the master section. This tool not only looks visually appealing but also serves as an invaluable aid for understanding and manipulating the spectral selections. With this analyser, users can visualise the frequency spectrum of their layered samples, make more informed decisions, and fine-tune their sound design.
It is worth noting that utilising all four layers simultaneously can be demanding on the CPU. However, with careful management of system resources and the high-quality 'Radius RT' playback mode, users can still achieve impressive results without overburdening their computers.

Identifying missing samples
IZotope's Iris 2 is a significant upgrade to its predecessor, with a host of new features and improvements. However, one issue that some users have encountered is the challenge of identifying and relinking missing samples. When a sample is missing, Iris 2 does not provide information such as the sample name or its original path, making it difficult for users to locate and relink the missing content.
To address this issue, users can follow these steps to identify and relink missing samples:
- Locate the missing sample: Without the sample name or original path, users must manually search for the missing sample on their system. This can be time-consuming and challenging, especially if the sample has been moved or renamed.
- Rebuild the absolute path: Once the missing sample is found, users must rebuild the exact absolute path as it was when the project was created. This ensures that Iris 2 can locate the sample in the correct location.
- Re-open the project: After rebuilding the absolute path, the project must be re-opened. If the absolute path is not accurately rebuilt, the sample window with user selections may reset, requiring adjustments to be made again.
- Relink the sample: With the correct absolute path in place, users can relink the missing sample to the project. This ensures that the sample is accessible and playable within Iris 2.
To prevent future issues with missing samples, it is recommended to keep the projects well-organized and maintain a consistent folder structure. Additionally, backing up projects and samples regularly can help mitigate the risk of losing content.
While Iris 2 does not have a built-in feature to identify missing samples, users can employ these manual methods to locate and relink the necessary content. Effective project management and backup strategies can also reduce the likelihood of encountering missing sample issues in the future.
